I have a 1992 pontiac sunbird with a 3.1 v6 engine.My car would crank over but no spark at the plugs.The problem was the crankshaft sensor was bad.The crankshaft sensor is located on the firewall side of the engine just above the oil pan cover.Mine was hard to get out, the plastic on it was brittle and you only had enough room to get one hand in the hole to work on it.

Ford is the only one I know of that uses a cutoff switch. GM use a relay usually in the under hood fuse box. Try opening gas cap & have someone put their ear to it, turn key on without starting, they should hear fuel pump hum for a few seconds, meaning it's working. If not check for blown fuse or bad relay, if you find something wrong with fuse or relay, replace it, & do the test again, if still no hum at the pump, it's likely pump is bad or you have a bad connection or bad ground.

you have to remove the intake tube and then it should expose the ignition system on the drives side of the cylinder head... or... follow the spark plug wires...

fuel pump?

it could be your throttle postion sensor

here you go

Smoke from tail pipe or smoke from under hood? A general rule of thumb if it is coming from tail pipe the color of smoke will tell you a lot.White and thick means head gasket failure, Blue means oil is being burned. I would recommend you check the seal of everything and make sure it is cleaned that had to do with vacuum or fuel distribution. EGR valve (gasket fails sometimes) IAC valve, MAP and MAF sensors, Fuel injectors, FPR (this will need replaced if leaking), Also check you coolant and oil look for signs of either one mixing with one another, smell you coolant and make sure it don't smell like gas either, look around where the head meets the block and make sure you don't have any coolant leaking there. The smoke if from the tail pipe makes me think head gasket and these are simple checks. They are not 100% diagnosis but can lead you to the problem. Also one obvious thing would be make sure no one put anything in your gas tank. I would most likely look at the injectors first then the head gasket next.

Check for loose connections on your ignition system, mainly around the coil.

idle air control valve

charge the battery then remove the negative battery cable and place a test light between the cable and the battery remove fuses until the light goes dim also unplug and unbolt the alternator as bad diodes can draw on the system it can charge and still drain the battery down
