1st take out the spark plugs, clean them and gap them to .035, starting your car is the goal right now and that gap puts the least amount of strain on the coil packs,better yet get a set of new plugs.

We use that plug gap on our turbo neons with 18 psi boost and COMPLETELY stock ignition system, very reliable.

If that doesn't get you started, check resistance at the coil pack between electrodes and compare to stock values, don't have my book in front of me right now, but I am sure someone can chime in.

Msd ignition and tach adapters have been known to fry coils, especially if you gapped over .040 on the plug.

If the coil packs check out, check for power at the coil pack, both sides at the connector harness while cranking, are both sides of the coil getting juice?

If spark is ok then your next place to look at is the injectors, get a mechanics sthesoscope (real cheap $14 at autozone or Pep boys)place the probe on the injector body itself, it should sound like a loud metalic tapping when the injector opens up during cranking.

If the injector checks out , see if you have enough fuel pressure or even if the fuel pump is working at all.

If the fuel pump is not working , check the fuses for the fuel pump, if they keep blowing it might be a bad 02 sensor since it blows fuses when they go bad and are tied to the fuel pump fuse.

Have to wait and see the results to go to the next set of troubleshooting steps if the car still doesn't start.
