Fuel Pump / Multifunction Relay Clicking

Wed, 25 Nov 2015 11:15:39 +0000

Hi I'm new here although I have owned my ZX for 15 years. It's a 1996 1.4i 2 door and has been a great car until this recent problem. When I key on, the fuel pump relay is constantly clicking or chattering as someone called it. The fuel pump does not prime and the starter will not engage. Also the keypad immobiliser usually has either red or green lights depending on status, now it has both illuminated. I changed the fuel pump relay for a different one, said to be tested and fully working but it does the same. The battery is fully charged if that makes any difference.

Has anyone got any ideas ?

1.9Td - Engine Stalling Problem

Sun, 03 Aug 2014 08:04:38 +0000

Hi I have a zx 1.9td sx. This car has never missed a beat but yesterday developed a very strange fault. The car always starts first time and runs as sweet as a nut. But since yesterday, once warm stops randomly, with no warning, no splutter just as if the key has been turned to the stop position. No warning lights illuminate, it just stops. When trying to restart it restarts, runs for approx 1 second and then stops again. It will do this for 2 - 10 times and then maybe run for 15 - 30 seconds and then stop again and repeat the start / stop process again. I have changed the fuel filter, replaced all the leak off pipes on the injectors as a pre caution. The immobiliser has been disconnected for years as it drove me round the bend entering a code every time to start the car! If you leav.e the car to go cold it will run perfectly until it gets up to temp and then keeps stopping. It never seems to cut out when you accelerate hard but as soon as you lift off the throttle it will die. Has anyone experienced this before or have any ideas what may be causing the problem??? I'm thinking it may be the solenoid on the fuel pump but am open to suggestions.

Many thanks. :-/

Car Brake Failure

Wed, 09 Jul 2014 15:25:29 +0000

I have a old 1994 Citroen ZX avantage.

When I was driving the car felt like it was stuttering and pulling to the drivers side (I thought I had a puncture) and smelt like it was overheating, although it didnâ€™t. Then when I put my foot on the brakes the pedal went straight down and the brakes failed without any warning apart from what I mentioned.

Just had a mobile mechanic come out and he reckond the drivers side disc is warped and reckons that was the fault. he has quoted me Â£70 to change and new pads as well (I think this is reasonable?)

However I am not to sure this is the problem as I have never heard of brakes failing because of this... I haven't driven the car on the road since they failed (luckily failed right outside my home) But drove it 6 foot in my drive the day after and the brakes worked well... but do not want to take it out and run the risk of killing myself or someone else should they fail again!

1994 Heater Matrix Replacement

Mon, 13 May 2013 23:02:17 +0000

Hey guys.

I've just brought a 1994 zx

It's the older model without a air bag.

The heater matrix needs changing and me and my dad are going to do it ourselfs.

I'm here for any advice you can give.

Any links to some tutorials.

I have the Haynes manuel.

And if I can't find it will buy another ASAP.

I know everything has to come out and that's not a problem.

But it's getting it back in properly that's on my mind.

Can any of you guys who have done this befor give me some

That would be great

Cheers

Fast Idle On Zx Diesel

Fri, 15 Feb 2013 18:13:12 +0000

Hi All, Posted on the other ZX section, so apologies for duplication. The idle rate on my 97 ZX SX TD has moved from about 1000rpm to about 1150rpm. Happened about the same time as I hit a nasty pot hole. The engine might be running a little rougher but if it is, it's subtle. The same with fuel sonsumption - seems to be relatively unchanged but still checking it out. Any suggestions much appreciated.

Citroen Zx 1.4i Sunroof Not Working

Fri, 24 Feb 2012 14:19:23 +0000

Hi all,

Just now happened, opened the sunroof, and did not realised that it opened just a bit, only when i tried to close it.

I checked all the fuses, are ok.

I do not know where the relay located is! On the right side of fuse box inside I can see 7 relays, but I do not know which one it is.

Does anyone know what could be the cause? Or, I would like to check the relay but I do not know which one is!

Thanks!

Rear Brake Pipe

Sun, 01 May 2011 15:16:05 +0000

Really hope someone can help me as I'm going insane.

I'm having to remove and replace the rear brake pipe from the cylinder to the flexable hose because the nut at the cylinder has been rounded off.

I can't undo the fly nut where the pipe meets the flexable hose. I have a size 11 fly not spanner and am bracing the nut on the other size with a suitable spanner. Its all been WD40'd up and left to soak but the nut will not undo, infact Ive started to bend the metal support its held to.

Any hints or tips and or advice solutions are greatly appreciated.

Help Changing The Front Bendix Callipers?

Wed, 20 Apr 2011 08:53:07 +0000

Hello all, I'm a newbie to both motoring and car maintenace and in need of some assistance with regards to my ZX 1.9 D (Non Turbo) 1997. I have been faithfuly getting help from the web and a Haynes manual, but have recently come acropper! I have had very spongy brakes on the old ZX with a juddering motion comming form the front nearside, which after some reading leads me to believe that this caliper is sticking and causing the brake fluid to travel back up the pipe, hence the juddering? Does this sound like a reasonalbe diagnosis? Any way I tried to initially bleed the brakeds to get rid of some of this spongy brake pedal and you've guessed it, even after soaking the nipples with WD, I have managed to snap both of them off!

So I have decided to replace both the font calipers in the hope that I will be able to eradicate this judder and firm up the brakes on this great car! But alas I cannot find a 'how to guide' anywhere, not in the Haynes manual (which seems to refer only to Girling brakes) or via a site on the web!

Also I am wondering weather I need to renew any other parts aside from the callipers. I have already renewed the front discs (non vented type) and the all of the shoes/pads both front and back when I got the car on to the road!

All help would be greatly appreciated! And many thanks in advance! D

1.4i Idle Control Valve

Tue, 19 Apr 2011 17:45:30 +0000

Does anybody know if any of the idle control valves from other models with the 1.4 TU engine with multipoint injection will be suitable for my ZX. There is a wealth of valves new and second hand but the correct one for my car seems to be quite rare. I can only find one on Ebay for £75.00, while most of the other valves are around £30 new. I dont really want to spend that much on a part, because it's over half the value of the car. The valve fitted to my ZX is a Magneti Marelli M3616 B16/00 and I think the injection is Siemens VDO. The car is a 1997 grey import. I beleive, acording to data I found online that it is the same as the B24/00 type.

Any help very much appreciated.

Intermittant Non Starting And Over Reving

Tue, 22 Mar 2011 21:41:35 +0000

I'd love some advice as i'm really not sure whats wrong with my car. As the description says its a 1996 1.4 petrol ZX with 90k miles. I bought it about 2 months ago from a guy who had only done 8k miles on it since 2003.

Since i've had the car it has sounded great when ticking over and been a nice responcive drive. however from the start it would occasinally over rev while idleing. It would go from normal reving up to '20' on the rev counter. It does this repetitivly and shounds like i'm tapping my foot on the gas pedal but i'm not. Its always done it when the car is stationary and usually when its in gear but with the clutch down aulthough it does do it in neutral to. I has now recently started suddenly drastically dropping in revs to the point where the dash lights flick on as though it was about to stall but then last second it brings it back to more normal revs.

Its also now become an unreliable starter. It starts first time every time in the mornings. however with a new job i have recently gotten i come home in my 3 hour break. This means the car runs for 20-30 mins, then is left for 2 hours before i try to start it again. It is at this time when its often not starting. It is like the engine is flooded, but having been left for 2 hours with no running it shouldnt be flooded.

If anyone has any idea i'm going to be having a more car savvy person have a go at doing the basic things (spark plugs ect) on friday. and we can also have a go at anything that anyone might suggest.

Any help greatly appreciated. :)

Zx Volcane Rear Suspension

Sat, 05 Mar 2011 13:34:22 +0000

I have a 1994 zx volcane TD and ive noticed my offside rear tyre is hitting the inside of the bodywork (when it goes over bumps etc), though there is no noise from the N/S wheel.

ive done a rough measure:

distance from the outer wheel arch to the tyre:

Offiside Rear: about 40mm

Nearside Rear: about 34 mm

so the offside wheel is leaning in more.

any suggestions to what the problem might be?

Clutch Zx 1.9td

Thu, 17 Feb 2011 21:20:58 +0000

The clutch on my ZX is gone. The cable had broken and after installing a new one I found that the clutch didn't work and makes a horrible grating noise when I press the pedal, accompanied by smoke coming out of the bellhousing.

Been trying to dismantle the clutch, taken off the front suspension on the gearbox side, driveshaft out, all wires and tubes out of the way etc.

On trying to take the bellhousing off I find it will only move about 20mm, then it won't go further. My suspicion is that the thrust bearing is somehow mangled into the pressure plate, when I move the clutch lever the whole bellhousing moves back onto the engine. If I try to pull the clutchlever further forward there is a springy resistance, an indication that it's attached to the pressureplate. I've been told by a friend who has a garage that the thrustbearing should just come out with the bellhousing but I can't get it to move.

Should I take the gearbox off, will that allow me access to the trouble area?

Or just force the bellhousing off, regardless of what it may do to the clutch, which is gone anyway. My worry here is that I might damage the lever mechanism or something else.

Also, my local parts supplier told me the ZX has a 'pullclutch'. I don't know what this means, mine looks like the normal push setup although there is an unused cable bracket on the forward side of the lever.

Anyone have experience with this type of problem? I'd sure appreciate some advice as I'd like to get the car back on the road asap.

Misleading Fuel Gauge On My Zx Diesel!

Tue, 15 Feb 2011 18:44:59 +0000

Hi my fuel gauge is very difficult to work out. I filled up the tank the other day with 54 litres of diesel, have covered 180 miles and the tank has suddenly droped to below half way and I have been doing motorway only at a steady 70. Sometime when I stop it shows 3 quarters full and then drops again!

I tried to replace the fuel sender unit today but couldnt find it under the rear seat????

What should I get out of a full tank and is this normal behaviour for the guage on these? Also does the warning light come on regardless of where the needle is or does it use a different detection?

Thanks

Clutch And Manual Transmission

Thu, 28 Oct 2010 20:12:24 +0000

Hello there!

I have ZX 1.8i -95 manual and I have a little problem with it:

The motor has begun shaking a little bit when driving normally. It doesn't do it always, but usually when driving with too high gear on and trying to throttle. Today I made some tests, when I was parked. No gear selected and motor on idle speed, I pushed clutch forward and released it fast. I felt that car tried to go little bit forward. It was like a tiny poke. I made it couple times and then it just didn't do it again, but when I release the clutch too fast, car begins to shake, but when I push the clutch again, it stops. When I release the clutch slowly, it doesn't shake. =D My tests were on idle speed.

Tomorrow I will check transmission oil level and so on, but if somebody have had these problems before, would be nice to know before I blow up the clutch and transmission.

Sorry about my bad english. :rolleyes:

1993 Zx Turbo Diesel 1.9

Sat, 23 Oct 2010 12:04:42 +0000

Just got home with new Glow Plugs and the probes on these are 29mm long and ones coming out are 24mm long. Can i fit these or will they hit the pistons? I have put some masking tape around an old one to make it longer and just turned the engine over and it does not appear that anything hits it. Don't want to do any damage but wanted to do today.

Any thoughts?

Zx Paint Code Location

Fri, 15 Oct 2010 12:41:12 +0000

Hi all, this is my first post so its probably in the wrong location so apologies if it is. I have a '92 J plate zx 1.9D avantage and I need to buy some paint for it. I have no idea what the colour code is or where to find it. I have found the VIN plate and chassis number but have no idea where the colour code is. Any clues would be greatly appreciated, many thanks, Nige.
