Make sure your wiring for everything is nice & connected in the right direction. Then start running pressure tests on the fuel rail, each cylinder bank, vacuum.

Sounds like you may have a huge vacuum leak somewhere. Is the brake booster line hooked up correctly?

Since you have screwed with the wiring I'll mention one more thing. There may be two white wires going to the ignition module. If you got those two wires backwards it might do this. One is probably the tach wire and one is probably the ECM ignition timing signal. If the ignition module does not sense the ECM it should keep running, but if the ECM send a signal on one wire for the IM to listen for the timing signal on another wire and it isn't there, it might die. I'd have to have an 89 book to verify these wires.

I would also strongly consider getting the ignition module checked at a parts store.

ok i checked the white wires and they are in their right spots so i boarrowed a scanner from a friend and hooked it up to my ecu did ascan on it and it said that i have 1 or more worn injectors ok now i was thinking instead of replacing one why not all 6 so i got on line and started my search i found 6 accel fuel injectors for $195.69 now i know this isnt bad seeing how they want $55.00 each at a auto parts store but my question now is what is the lbs./hr. on stock these are rated at 15lbs./hr.

They are probably close to that. At one time I used to know, but I'm getting old and forgetful.

I think they are 19lbs/hr, the last I recall .

the 3100 is 17 and the 3.1 is 16 so I would say 15 is probably right.

Depends on what PSI they are rated...... Don't compare Ford to GM, etc...
