2004 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic 141000 miles
i HAVE REPLACED THE FUEL RELAY, STARTER RELAY, BATTERY AND KEY SWITCH MODULE. THE CAR RAN FINE BUT NOW IT TURNS OVER BUT WON'T START. I HAVE ALSO REPLACED THE FUEL PUMP ABOUT A YEAR AND 6 MONTHS AGO. DO YOU HAVE ANY SUGGESTIONS.
To determine if its fuel or spark problem do below
Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
