visually check crank sensor(common problem)
check for fuel pressure on fuel rail there is a shrader valve for that. pull a spark plug wire and confirm spark.
make sure air box isnt plugged.
if all that is good change the control module. good luck hunting

Most probable cause is a bad BLOWER MOTOR RESISTOR (BMR). This part is located underneath the right side of the dash mounted into the blower motor housing. The BMR has a circuit board that is suseptible to corrosion and moisture damage because it is in an enclosed area with much condensation. After replacing it a couple of times, the 3rd time I dipped the circuit board in TOOL DIP - the stuff you rubber coat screw drivers with - have not had a problem since (3 years).

Sounds like it's you spark plug leads. Depending which engine you have in there, if you have the 2.4L then it is a module.

The ignition modulator may have to be replaced, you can pick one up at Auto Zone and it's still pretty expensive so you may want to try the Salvage yards. The ignition modulator's are common interchangeable part for the GM line so you can get one from a newer car then your 89 cavalier. Good luck and hope this helps. I believe Auto Zone can also test the ignition modulator too, the modulator is what the coils sit on.
