2001 2.2 Hdi Auto, Two Or Three Attempts To Get It To Start!

[Old Mosher]

Hi. My trusty steed is sudenly getting lazy in the morning and takes a good amount of cranking to start.

I am a little nervous that this will get out of control in a few weeks/days when our glorious british summer abruptly ends and the frost starts.

 

So far I've looked for/at

 

Air leaks into the fuel lines.

The lift pump is working ok.

The fuel filter was new 4kmiles ago.

 

The glow plugs....where are the glow plugs?? I can't find them!

 

 

My Autel FR704 has found

 

P0402 F32. EGR control-EGR solenoid circuit in short-circuit to +, or - ( I havent a diagram of this so could be fun)

P1421 F2. Upstream cat. converter temperter signal (cat1)fault-short circuit to earth or open circuit or short circuit to + or starting coherance. (always had this, never a problem)

 

 

It went all the way to southern Spain and back for our holiday and didn't miss a beat. To days back in old blithgy and this pops up. What do you guys think it is???

[Old Mosher]

Update...at the bosch 9635704380 EGR control valve Im geting 15 ohms. The EGR valve holds vacuum ok and slams open and closed ok. Having said that it is blanked off at the manifold and has been for months.

Glow plugs are on the back of the engine but I shouldn't worry too much about them. HDIs start without them and are only needed at well below freezing.

could be one of many things from a dodgy cam or crank sensor or low fuel pressure from either of the diesel pumps or a starter or battery or imobiliser. youl be running around in circles and it will send you mental in the end. i think youve got autotel diagnostic if it has live data then go tp that and crank engine so you can see whats happening. If you havnt then bite the bullet and pay to have it plugged in. if your near newcastle then il plug you in for a bacon sandwich and a cuppa

Is your starter turning over fast enough? If it's sluggish it won't built sufficient fuel pressure to fire.

Yep thats the one, but it won't talk in live data with my C5, dont know why. So the bacon sarny and cupper sound like a cunning plan. With the price dealers charge for diagnostics the fuel cost from Nothants to Newcastle would be less anyway.

I can't even test it till later today as I managed to snap a plastic reducer on the bypass hose doh.

New one in today so ill get back to you.

Hi. Yep know what you mean but yes its spinning the same as always.

[coastline taxis]

just a quick simple one. Put the ignition on and leave for 10 seconds do this 2 or 3 times them try to start it

[Old Mosher]

Ran ok last night but this morning it was an epic fail. No time to play with it at 5am, just jumped in the Estima and of to work. but ill give it a swift kicking tonight.

No joy with that one. I can crank it all I like now, it's not starting.

 

I put the Autel on it and it now has the code P1135 f8 3rd Piston deactivator-shrtcircuit to positive or short circuit to earth or open circuit.

 

What is the "3rd Piston deactivator" ?

where is it ?

and what do I hit it with to make it work ?

[coastline taxis]

it sits on top of your diesel pump. youl see two wires going to it. In the old days (ha ha) before diagnostics it was called a stop solenoid. and by your none starting you will now know what it does. looks Simple enough to replace but having said that ive never replaced one so cant really be much help to you. but check wiring 1st for power or breaks

[Old Mosher]

found it, un pluged it, pluged it back in and the fault code cleared. Not the problem though. thats still not starting.

Just to p on my chips, the cars gon into power saving mode and now I cant close the drivers window. Ok all I have to do is start the engine and. . . . .twats his head on the garage wall in frustration and sings "There's a hole in my bucket, dear Liza, dear Liza There's a hole in my bucket, dear Liza, a hole"

Its been a long day!

[coastline taxis]

oh dear oh dear oh dear

fully charge the battery then plug the diagnostic back in and cranki it over and see what code comes up

[Old Mosher]

Borrowed a snapon solus pro kit of a good frind of mine.

this is what its reading.

 

Fuel press at cranking=87---109bar

at 800rpm=251bar and press regulator open cycle ratio 16% ( got it to run with a small spray of easystart, Hate the stuf but needs be and all that )

injector 1 flow correction = - 1.52 mm3/stroke

injector 2 flow correction = - 0.51 mm3/stroke

injector 3 flow correction = - 2.78 mm3/stroke

injector 4 flow correction = + 5.06 mm3/stroke !!!!

 

Could that be a clue ?

 

Also I poped down the scrap yard and got a fuel press transduce, a filter housing lid (fuel pressure relief valve) and an EGR valve acctuator. Ive fitted them all to no effect.

whoa slow down a bit.

Bits from the scrappy could be gossed .

 

lets start again

car runs fine when started with no engine miss and plenty of power.

car has trouble starting, once its started does it start ok for the rest of the day or is it every time you start it

is it a bosch fuel system

[Old Mosher]

"car runs fine when started with no engine miss and plenty of power" Yes, Its no hot rod, but its the same as its always been.

 

"car has trouble starting, once its started does it start ok for the rest of the day or is it every time you start it" The first time I start it its a total git and needs a small wiff of easystart. after that its just a reguler git and will go if you give it a good long crank or two.

 

"is it a bosch fuel system" Yes it is...Is that a good thing?

Bosch fuel filter - reminds me of some work by coastline taxis which found the early ones have a bi metal strip in them to direct cold fuel to a heater and which if faulty/worn away will give fault code P1138 and stop the car running. The fix will be a new filter body if this is the fault. This may be one of the things coastline taxis will suggest. Edited September 2, 2012 by paul.h

[paul.h]

May be a test on the filter body would be to warm it with a hairdryer and see if it starts.

[Old Mosher]

Hi Paul. Ive not found an f 1138 so far.But I gave it a warm up last night, no joy. On my filter there is no connector on the body but it has one on the lid. I have three lids to hand, one was ok apart from a small crack in a hose connector that had been repaired. I only switched from that lid because I was driving all the way to Spain. Even that one makes no improvement.

I also did a leak down test on it. No 3 was the leakyest with 2&4 a close second. Over all I would say within 10%

[Old Mosher]

Dropped it in to a Bosh injection specialist this morning. Bracing my self to the bad news.

[Old Mosher]

Pump pressure regulator (DRV valve) £275 fitted inc Vat. Should be fitted by tomorrow so I'll let you know how it goes'

[Old Mosher]

Conclushion.

It should have seen generating 260bar to get it started but couldn't manage to get past around 210, in my case it turned out not to be a case of where is it going but why was it not there in the first place.lol

The technician fitted a new pressure regulator and all is now as it should be.

Thank you John, Costline and Paul for all your help.

Till next time. :-)
