AUDI 90cs year 94
OK SO THIS IS MY PROBLEM, THE CAR WAS FINE ONE DAY HOURS LATER IT DIDN'T START AGAIN.
HERE ARE THE SIMPTOMS.
CHECK THE FUEL PUMP RELAY AND IT WASN'T CLICKING. IT WILL OF I DO IT MANUALY(open relayand moved the switch by hand). I TRY A NEW ONE AND IT WASN'T IT. I DONT KNOW WHAT THA F!@### ITS WRONG WITH IT. ITS THERE ANOTHER RELAY FOR THIS OR ANYONE HAD THIS PROBLEM BEFORE?

 

CHeck the fuel pump... I had this problem on my 5000,CS turbo, I found that initially it wouldstart and run then If I were to shut the car off there would be no relay action , only that it would be getting hot, (Cause it was trying to actuate the fuel pump and it was seized....a while later (4 to 5 hours the pump would un-seize and start again...
I was told that it might be a pump from someone on this site and so I replaced the pump and had no further problems....)

 

I install a new pump, and the car was running fine, just that one day it never turn back on.
do u know what can cause the relay not to click. I bought a new relay from the dealer(not chee)
and I still get the same problem?

 

Mostly when the fuel pump siezes up it causes the relay to over heat and stay opened or closed..
