2002 Pontiac Grand Am Question: Cranks but wont start



jimmycouz, 2.2L 4 Cylinder, Adrian, MI, June 27, 2010, 08:23

The engine will crank but will not start. I have replaced the spark plugs. While doing so I sprayed starter fluid which allowed the engine to run approx. 5secs. I have replaced the fuel filter, checked the fuel pressure which is at 60lbs. Check all fuses. I have 12.2 ohms at fuel inj. and voltage at the wire harness. I also tried a new ignition module and no change. What would be my next step before taking it to the dealer?

    You have engine developing compression and cranking over and have verified fuel pressure. DO you have spark at the spark plug and fuel injector pulse. If you have lost spark and fuel a sensor like cam or crank angle sensor could have failed but you need a wiring diagram and test procedures are just replacing parts isn't a cost effective way of getting your car going. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online
