94 Oldsmobile Cuttlass Supreme (3.1) won't start. When I go to turn on my car, it sounds like it is going to start-- but doesn't ever actually turn over and start.I have tried jumping my car and also putting it in N and tried starting it.

Recently after putting gas in my car it had trouble starting, but then it did start and was fine up until the next day when I drove it to my destination and turned it off. After waiting a few minutes I attempted to turn my car back on, it turned on but it didn't actually drive almost as if it started, but didn't work. After that my car wouldn't even "pretend" to start, but instead made the usual noise all cars make before they start but doesn't turn over.

Please help it is an emergency

Love this site :-)

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-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,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems

with compression and valves opening and closing at the wrong time/broken or jumped timing

belt/chain
