I'd check for spark first. If your getting spark, your ASD relay is working.
Get a multimeter.
Pull the ASD relay. If you have questions on what terminal is which, it should be printed on the bottom of the relay itself.
With the ignition off, you should have voltage at terminal 30 (of the power distribution center for the ASD relay). This is your "hot" wire. Wiggle the wiring harness and make sure it keeps getting voltage.
With the ignition switch ON, battery voltage should be present at terminal 86. Again, wiggle the wiring harness and make sure it keeps getting voltage.
Now, you will need a helper. Have your helper hold the key in "START" and check for a good around on terminal 85. Again, wiggle the wiring harness and make sure it keeps getting a ground. (Note: I've never personally checked for this, but it *should* work)
If that checks out, theres really only one thing left. Check continuity between terminal 87 and either the distributor coil electrical connector or one of the fuel injector electrical connectors (try both of the wires on each connector just to be sure). Again, wiggle the wiring harness and make sure it keeps continuity.
If there are any problems with the steps above, either a fuse is bad some where, or there is some wiring problem.
If that checks out, it's onto different gremlins.
