Definitely sounds like a fueling problem. You've checked the fuel pump relay?

Are the TPS and MAF correctly connected to the proper devices? Is the DME working?

how can i check if the dme is working ?If there's an aftermarket chip inside, there's a good chance it's popped out of the socket. you can just open the DME and look inside.

Other than that, the car would need a "brain transplant." Swap in a used DME from a working car and see what happens.

Just a last ditch effort, verify that the cam sensor is working ,I had a problem with corrosion on the connectior. Car wouldn't start, just turned over & over until I cleaned the contacts.

yeah i'll give it a check, but i still think its the dme

checked the dme connections, tested them out with some bridge-ing and everything works fine, so i'm 95% sure that its the problem

does anyone have a dme for an 87 325i laying around i can borrow for some tests??


lemme know
thanks!!
