Guest gaztank Posted January 9, 2011 Posted January 9, 2011 hi guys, i have had a problem with my car not starting. i turn the key and the dash lights come on but the engine will not turn over, it's dead.I cannot take it out of park either. i called out green flag and after a while of going through the normal battery and starter check he checked the fuses to find the 10 amp f18 fuse blown which protects the flywheel angle sensor, automatic gearbox lever switch, and the diagnostic socket. why would this blow now. it blew again a few days ago in the pooring rain and it was dark, they are not easy to remove. so is there any body out there who can help me. It was only serviced about 3 weeks ago, that was only a oil change service that would not have any effect. i also have a passenger door lock problem, i discovered its not the solinoid but the lock sticking. wd40, again i just wondered whether this fault was causing my f18 fault. I look forward to any help. Gary. Quote
coastline taxis Posted January 9, 2011 Posted January 9, 2011 A quick guess by reading your post would be to check for a short or faulty component or even water causing a short Quote

I had only left the car for 5 minutes it was still warm it just didn't start. there is no water coming into the car. is it normal for the footbrake switch to draw a large current when faulty??? gary.

coastline taxis Posted January 9, 2011 Posted January 9, 2011 Im glad you no why fuses blow. Had you said in your original posting that youd checked your wiring then it wouldnt of been mentioned. Anyway had something very similar on a 55 plate c5 kept blowing the fuse and leaving the starter dead. It turned out to be the solenoid on the starter shorting out and poping the fuse Quote

It turned out to be the solenoid on the starter shorting out and poping the fusei dont think it is the starter motor as f18 fuse protects the auto box switch, fly wheel angle sensor and diagnostic socket.so which fuse was blowing with your starter motor fault, was it in the engine fuse box or in the glove box.any way the car would not attempt to start if it did not know where the fly wheel was. when the fuse is blown the ignition will come on as normal but you cannot move the gear shift out of park as there is no power to the solinoid. i think i will check the switch/loom at the brake peddle and the looms under the carpet near the transmission. and then it will have to go to the dealers to get the diagnostics and electrics tested. once the fuse is popped in it starts fine and works ok for a week and then suddenly pop. another fuse blown, if the fault was always there then i might find it quicker, that is the problem with intermitant faults it could work ok for weeks for all i know. i have scanned the forum for similar fault with no luck yet.gary Quote

Over the door lock fault i spread loads of petrolium jelly over the electrical plugs in the door frame to keep the water out its been ok for the last few days. i went to adjusted the door locks,to ease the pressure on the lock when the door closes but they are not adjustable which is a shame. i look forward to any replies, regards gary.

coastline taxis Posted January 15, 2011 Posted January 15, 2011 It was a 30amp in the engine bay fuse box cant remember the f number. things id be checking would be wiring not just for breaks but continuity and resistence.ignition barrel. And a daft one would be the imobiliser as when it kicks in youl get every sympton that you describe and your having trouble with door locks wich is linked to the imobiliser. Having said that ive not had much to do with automatics so dont no if the imobiliser would disable the shift lock or not.Have you got acsess to diagnostic equipment Quote
Guest gaztank Posted January 16, 2011 Posted January 16, 2011 I was thinking about the first time the fuse went, It was misty, I think I had the fog lights on. Well the fuse has been ok over the last week and I haven't used the fog lights. I checked the rear light clusters to find the off side rear cluster cracked and leaking in water to the fog lght. I emptied out the water and checked the plugs and bulbs, the plugs were letting in water. So I cleaned up the contacts on the bulbs and plugs and pasted petrolium jelly inside and out of the plugs and cleaned the bulbs and jellied the cables too. I will order a new light cluster monday. lets hope this was the problem with the short. gary. ps thank you for your info mr coastline taxi man. Quote
