First determine what ignition sys yu have, is it a DIS, (direct ignition system) which does not have a distributor,
if you have a distributor first i will check the ignition rotor, make sure it is not brned through and if you find that the ign rotor is burned replace the rotor and also the spark plug wires which caused the rotor damage.
secondly if you have a distributor check that the pick up coil is in good condition check for continuity using an omh meter, disconect the wire coming out of the pick up coil (the one in the distributor, not the coil inside the distributor cap!!) and connect an omh meter to it if you have ressistance the the cois contunity is good however make sure that the pick up is not grounded if the pick up is ok the you have either a ignition module in the distributor is bad or the ecm is no good. Hope thsi solves the problem, Good luck ( Roby).
If it is a DIS the the first thing to check is the crank sensor, suing an omh meter and if the sensor is ok most of the time the vehicle's computer (ECM) has to be changed.

Usually answered in minutes!
we are working on a 1991 Chevey Cavaleir. There is NO spark. We replaced the Spark plugs/wires,ECM,Coil Pack, crank sensor, and shecked the fueses and replaced what need replaced.
What happend was this I want to the store shut the car off came back out and it would not start back up. I wait two weeks before trying to start it again. A friend checked it for spark there was none. so he call a guy he knew that worked on cars and that is how we started replace everything above.
When the Crank Sensor was removed it fell apart in there so thing had to be taken apart to get the rest of it.
Can anyone help ??? We are all at a lost....
my 2001 cavalier wont start have no fire at plugs and no fuel pump
Have you checked for a cranshaft signal, if there is not one the coil will not fire.
