I have a 2006 GRAND PRIX the problem with it is that it has trouble starting. At first I thought it was the fuel pump and crank sensor but a mechanic told me it couldnt be the fuel pump cause the car runs fine ones it starts and that it couldn't be the crank sensor?
have the same problem?

Going to need more info, Is it a crank no start when failing, if so you are going to have to see what is missing, (spark, fuel, injector pulse), that will give you a direction to start diagnosing.

Same problem. Changed the crank sensor, harmonic balance, ignition modual, and a new fuel pump still no spark.
