Hello. Begin by testing your battery by seeing if the headlights come on. If they do, check all of the connections from the battery to ground and battery to the charging system. You most likely have a bad battery or a bad charging system or a bad connection. Physically move the wires near each connection to make sure everything is very tight. Also check to see if there is a corroded connection which could be impeding things. Joe

Do u have fuel pressure? sounds like the electric fuel pump has failed, this pump is located inside the fuel tank, the fuel tank must be pulled to replace it, an easy way to see if the pump is working is to buy a can of spray starting fluid from any auto parts store like Kragen, Napa and Autozone, also hardware stores carry starting fluid spray cans, remove the air intake hose tot he engine and while the engine is being cranked over spray the starting fluid in, if the engine starts u have a defective electric fuel pump.

    when u turn the key on the pump will only run for 1 second, then the computer turns it off if the engine is not started, so by jumping it u are just overriding the computer shutting the pump off, check the fuses to see if they are blown, the computer and fuel pump fuses are in the underhood fuse box, they are marked ecm, think there are two of them, suspect u have a blown engine wiring harness fuse which means the wioring harness has rubbed through somewhere on the engine and shorted out the system, this causes the no fuel and no spark condition, does the check engine light come on when the key is turned to run?

I have a 2004 cavalier that has a new coil new starter new module and new crank sensor in it but want start it gets gas and oil


if fuel is getting to injectors, are the injectors plugged ! if you are getting fuel to engine plus a good spark it should start. check the plugs for fouling out. maybe there not firing right. if a plug or plugs are not firing. then they will be wet on the tips of the plug. crank engine a few times, then pull the plugs to see if they are firing.if not firing, check for bad plug wires. theres so many things that can cause this. its hard to say without being there!

Had no spark. Replaced ignition mod, 2 coil packs, and computer. I now have fire; problem is engine will not run, the fuel injector sprays fuel (too much i think). When i unplug the injector the engine...


Check for any wiring pinch which might have occurred when the injector was replaced. The injector is driven directly by the computer, so it seems to point at the new computer as being faulty. (pulse signal is always 'on')

Tuned up a 1993 chevy cavalier has spark won't start


Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

My 95 cavailer just starting having a problem. motor jolts, has loss of power climbling a hill misfires , engine doesnt die it will start right up but runs poorly also can smell a odor not sure if its gas...


I would check to make sure your spark plug wires are not coming loose from the coil packs on the back of the engine, i had the same problem with a '97 cavalier and then the check engine light started to flash meaning it had a catalyst threatening mis-fire.

also check to make sure you have the correct order, these things will run with the wires mixed up but they are gutless.

a new fuel filter might not hurt either, they are easy to change located near the back axle, one nut and a quick connect fitting.

92' Cavalier 2.2L 4 cyl. runs but has a miss coming from #4 cyl.


Matter not whether plug fires out of engine. Put it back in and clamp a timing ligh to it. If the light won't fire, you don't have enough spark to fire cylinder, hense miss.

92 cavalier 4cyc. with coil pack cranks but won,t start checked fire has none


if the car crankes and wont start there are a few things you need to have for it to run. spark fuel and timing. check for spark at plugs. check for fuel preasure and injector pulse. if these are o/k then check engine timing. if everything is o/k then you probably have a major vacume leak.
