93 90cs starting problems
I have a 2.8L 93 90cs quattro thats been giving me starting problems. Only starts about 30% of the time and once started it runs fine(maybe a little rich). I found out if it does'nt start it's not getting any spark. Just woundering if anyone can tell me which sensers would prevent it from getting any spark? is there a way to flash the codes without a reader?
thanks for your help

RE: 93 90cs starting problems
I think I'm getting closer. I did find a vac. leakthe green hose coming from the fuel pressure reg.was disconnected at the end by themass flow senser I reconnected it and still nothing. Got spark now (don't know why I didn't have it before) I took off the fuel line before the regulator, cranked the motor and no fuel. So I figure it's the fuel pump. Or is it the relay? Is there a way to narrow it down? I can't find the fuel filter does anyone know where this is located on this car. I do see a canister on the bottom of the tank and I figured this is the pump. Or maybe its the filter? Do I have to pull the tank out to replace the pump? thanks for your help

RE: 93 90cs starting problems
the fuel filter might be in the engine compartment ... you might have a faulty fuel pump .... the pump can be replaced without removing the tank ... check the fuel pressure to narrow down fuel delivery problems
