    the 03 cavalier with the 2.2l eccotec engine doesn't have a distributor cap or wires the plugs sit down int the head and the coil packs connect with boots to the plugs. the ignition module takes the place of the distributor controling the spark on cylinders 1 and 4 and cylinder 2 and 3.

I need help locating a module ignition modulator in a 2003 Chevy Tahoe

Who told you that one ? Module ignition modulator 2003 Chevy Tahoe ! No such thing! Your best bet would be to take your vehicle to a qualified repair shop .
The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions. This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.

I have a 2003 chevy cavalier with a 2.2 4cyl engine. I replaced the fuel filter and it is still not getting any gas up to the front. I think it is the fuel pump, because the fuses and relays are good,...

no but the ignition module control the primary circuit of coil but at the same time tell PCM the engine rpm and then give signal to injector to spray
do you hear the pump working while key on engine off for 2 sec then while cranking have someone listen at tank fuel cap off

Chevy Cavalier Random Misfires - Rough Idle

Try this:
-Check fuel pressure. (read in its repair manual to see how much it suppose to be.) If it's low then the fuel pressure regulator or fuel pump is defect.
-Is it fuel injector...? Then check its resistance of each injector when it's cold. If it's not within its specification then replace new one

Good luck

89 Chevy 2.8L #3 & #6 misfire.

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.

No spark cylider #2 & #3

First things first, is your check engine light on and have you had the codes read off of it? The problem most likely is the module but it could be other things too. It is always better to do all the diagnosis you can before just throwing parts at it. At least pick up a manual for the car that should tell you how to diagnose different parts.
