Problem for Volkswagen Cars
Generic problem for all Volkswagen Passat Cars
Car will not start, had
Car will not start, had been idle for some time as owner had removed battery and would not start once replaced. When ignition turned on fuel pumps would not run - have now over-riden the relay with a switch- however ir does seem NO power to activate the relay. Once pumps running still will not start, now no spark, wathing the spark plugs or coil output it will fire ONCE and then stop. Turn ignition off then on and will spark once and then nothing. Called in a mobile auot electrician - he basically could not find problem (his answer like numerous others - gasoline and matches)Did actually start while auto electrician was there - he had opened the air/fuel system and was wiggling something? somehow it must have been firing at that stage. Did find a vacuum leak or holes in air pipe and thought that was reason so have repaired it - will not start - very frustrating
Auto electrician had also put some form of over-ride power on a terminal in the ECU to power fuel pumps - this may have allowed the ignition at the time also. I have a manual But Stumped. Think maybe is the airflow sensor? It is a 1990 Passat 1500cc Gt I think
Thank you for your time, much appreciated

- previous answer gave another website link? and then asked for the results and then would help? samarins.com/diagnose? seems stupid to me as tried the website and could fined nothing of any significance other than more time.Have now started the vehicle, with the previous auto electrician and it was eventually as I suspected, the fuel pumps had to be powered or relay over-ridden, using the same wire he had previously used from the ECU as somhow this sent signal to igniter also(has ignitor/ignition together) Auto electrician and myself still unable to source 'actual' problem, only remedy or bypass the effect. Car started very roughly and idled too high, now it seems the idle controller- which manages some form of airflow pipe- is not opersating.
It was the opinion of VW dealer that the ECU would be a last resort also the opinion of the Auto electrician that merely disconnecting battery removed or wiped any recorded 'fault' in the ECU.
Would appear unless 'cause' is found and repaired the car will just be a constant problem if just continually attempting to overide the faults.
Look forward to response from someone who may possible have VW experience(and managed to survive and stay sane)
Thanks

- interesting response, considering the auto electrician is in a blxxdy garage, DarlingJun 24, 2009
- i think checking ve and -ve? if not done by an auto electrician - is saying very little of his competence. Such was checked prior to calling in an auto electrician as was all the fuses checked.The engine is running and has considerable spark - if bypassed -

When you read the issue at first I thought it is an anti-theft device in the car that would have stopped you from starting this vehicles as I have heard similar cases. But it would not hurt if you checked out the electrician may have missed it.
Check also the fuel pump relay under the dash near the steering column if it is working. Also an oil pressure switch which serves as back up to this relay is also associated. Check both if they are in good condition and their wirings. If you can get another ECU to test to your car you can eliminate the ECU as the source if you still see the symptoms.
