1998 Grand Prix SE 3.1L

[mine2a]

Car won't start. Problem began as intermittantly dying when pulling up to stop light. Progressed to final breath and towed home. Have tried replacing fuel filter, plugs, plug wires, computer, ingnition control module, EGR valve, Starter moter, because dealer suggested. Car has been on engine diagnostic computer twice, once at dealer and once in an idependent garage. Neither showed a problem.

Need help!!!

Is it not cranking over or just not getting ignition?

Good idea to check basics such as fuel and spark. For fuel check fuel pressure at the injector rail. For spark it could be the 24X crankshaft position sensor (CKPS) since just about everything else was changed.

Don't have car in my possession yet expect to have in about a week. I've been told that it cranks but won't fire. All I really know is what I'v told you so far. I would have expected the dealer to look at the fuel and sensor. Are they not smart or what? I'll check the two items you suggested as soon as I have the car.

Thanks
