There are a multitude of reasons which might allow your engine to crank without actually starting. Without a great deal more information, any suggestions are really only guesses as to the cause of your problem. That having been said, here is another possibility you might consider: The 1996 Cavalier uses a form of GM's original theft deterrent system, a system which, when activated, will cause the fuel pump to cycle off after initially "charging" the fuel line. If your engine is cranking, but not starting, you are certain you have a spark at each of the plugs and you have good quality fuel and plenty of it (at least one quarter of a tank full), the theft deterrent system may be activated and causing your problem. The system is designed to "look" for the proper key to be inserted in the ignition switch before allowing a "starting condition" to exist. An attempt to bypass the ignition switch will activate the system. However, the system gets its power through the same circuit which provides power to all the guages on the instrument cluster. A blown instrument cluster fuse (labeled "GAU" or "GAUGES", located in the fuse panel) will cause activation of the system, allowing the engine to crank, but preventing the engine from starting. Check that fuse and replace, if necessary. Good luck.

You must make sure the engine is creating the appropriate compression remove a spark plug and install a compression tester disconnect all other spark plug wires so the motor does'nt start during testing and check to make sure the motor is creating at least 100 - 150 psi on all cylinders if so the mechanical health of the motor is in tact. if not you may have to replace a timing belt. If it is an interference type motor and the timing belt is indeed broken or jumped a tooth the valves may be bent and extensive engine repair will be needed

Where is the emergence shut off switch to reset fuel pump on 1996 chev cavalier 2.2


Hello,
To answer your question there is no inertia switch. So your only options are the fuel pump relay, the fuel pump itself or bad wiring. I would start by turning the key to on and see if the relay clicks. If it does then more than likely you have a bad fuel pump

I have a no start with a 1996 Ford Probe GT 2.5. She turns over, has fuel and spark


If you are sure you have fuel and spark the only other posibilty is engine damage. The most likely is a broken timing belt and the cams are not turning.. Go back and check that fuel and spark again.. Don't look for major problems until you have really checked.. Squirt a little fuel into the intake manifold ahead of the throttle body.. If it fires you have spark and no fuel.. The computer may not be telling the injectors to open.. I had this problem once on a chevrolet and it turned out to be a clooged fuel filter.. buying gas in Mexico.

Was running fine on interstate, started losing power on hills, cut off would not restart


When it fails to start-- do you have spark or injector pulse or
fuel pressure-- while cranking--?

Could be a crank sensor --but replacing parts with no testing,
is not the way to go --learn how to test components

Could be a crank sensor failed, fuel pump or timing issue,
chain or belt whatever it has

Look at Professional Scan Tool Data--codes or not, that is
always where you start & check the battery out is always a first
step as well

I have a 94 chevy cavalier. and it wont start. the coil is fine and so is the spark plugs. and it does turn over when i crank it... i would pump the gas a couple of times and it would seem to try and start...


you need to check see if it is getting fuel sounds like a clogged fuel filter and when you pump the fuel peddle you are puttting it clear flood mood which may also be leaking fuel injectors and flooding the cylinders with fuel but most likely is a clogged fuel filter try spraying starter fluid in throttle body and if starts its clogged fuel filter

96 Cavalier. "sometimes" wont start


The fact that you get enhanced ignition by physically enriching the fuel air mix indicates that the normal mix is too lean, either too little fuel or too much air. 1) Check for leaks of un-metered air in to the air ducting and inlet manifold. Look for cracks and poor joints to all vacuum lines including the evaporative emission recovery lines. 2) Check that the EGR valve is closed off at start up: this should stay closed until engine has warmed up. 3) Finally check that the coolant temperature sensor is working OK; the sensor should be informing the ECU that the engine is cold and the ECU responds by ensuring an enriched fuel mix (by prolonging the injection cycle) during engine warm up.
