Well first of all I found out why it would not even crank. I got a starter for a 92 stang and in the years around this time there was a lead wire that went from the relay to the solenoid. Well nead less to say I did not do this not knowing what it was, which in turn it would not recieve the signal to trip the solenoid and turn the starter. My fix was I got one for an 89 which only need the ignition wire.
Since I got that fixed I tried it out. It was cranking, and I could smell fuel but nothin. I pulled a plug and no spark (at least so far I have 2 out of 3). I checked the cap and the contact points were rather rusted to I sanded some of the rust off each one and nothing. Also the gaps on the new plugs are within the toloerences. And I checked to make sure that all the wires were snapped in. So what are some posibillities. And if something isn't right, what does the ecm shutdown, the fuel injectors or the spark?
No spark

take the wire off the plug, put a screw in place of the plug, hold the screw about a quarter inch from a ground source, have someone crank the motor, then see if theres spark, also the plug wont spark if its out of the engine and not grounded

Pull coil wire at distributor and see if it has spark first. If it does but not getting to plug it's easy fix. If no spark at coil then you know you need to dig deeper.

hey cee, a little off topic but do you think you could call me soon about those headers? I really want the full lengths now that I bought that other pair and saw how cool they look. But anyways this is all im waiting for to complete the swap, so I would appreciate a call soon....... and I can do $300 shipped

Ok yesterday I checked for spark again (this time to a ground) and nothing. Couldn't find my cousin's 12v test light to see if anything is getting to the coil. And I have it wired according to the 89 schematics (that is the harness I have) and I know the ecm is getting power. The way it is wired is that it gets power from the wire that feeds the coil which trips the ecm relay and the fuel pump relay will not trip till the ecm is tripped. Can a coil go bad just sitting there? And what can you all speculate can be the cause if the coil isn't getting power? I have not checked to see if the injectors are getting the signal, so how would I go about that, test light, etc? Like I asked earlier, what does the ecm shutdown, the fuel injectors or the spark?

umm this may help you or not but when I first wired my truck up I had power and everything from the wire I used as my source, and I hadf no spark. a buddy came over and I got him to turn it over and I discovered the source had no power during crank, so I'd turn key on everything would work then click no power.
