1998 Dies When Running

I am at the point of no return. I have spent thousands on this problem. Had it with GM, left the car with various independants, had fuel pressure checks etc.

The car runs great and then dies for no reason, no fault code shows up. After it dies it re-starts no problem.

Has anyone experienced this?

Based on all he postings I have been readings for this thread, there seems to be a problem with a good ground. Has the ground been check ? do a scan on this thread looking for ground wire problrem

Sounds like a relay problem.

I have five words for you! Change the Crank Position Sensor! Acts just like you describe. Will not throw a code. If you have changed it already check the wiring and the cam position sensor. But the CPS should do the trick.

I replaced the Crank Position sensor. I will try the Cam sensor, wiring and also Grounds, and Ingnition module connecitons.

Thanks

I had this impossible to find problem on a 95 Bonny ran a new wire from the Engine block to the H frame and problem went away. Not Engine to negative of battery or other battery ground connection. Before adding wire you could check block to H frame resistance if only 1 - 15 Ohms the engine ground is fine. Mine was 30 Mega Ohms of resistance before replacing wire, and solving the dying problem.

Mine CV does EXACTLY that, and i know for a fact its the fuel pump. In your case i still believe its a relay or a faulty connection coming from the cars computer.

I know its my fuel pump because right before it dies, i hear a strange "farting" noise out of the tank (the pump) then it dies as soon as i come up to the next light. But it starts right back up.
