MPFI help
I just wrapped up my dpfi to mpfi swap on my 89 EE wagon. Everything was going great until I tried to start it
. I checked and re-checked my wiring and it all checks out. The car cranks and tries to start then sputters, backfires and dies quickly.
What I have questions about:
I used obd1 injector clips and I had to modify the injectors a little bit. Is the wiring reversed or anything like that? I know the colors are different compared to the obd0 ones.
The distributor is in unknown condition but there was very little shaft play
I am getting a CEL for a code #10 which is for the IAT (Intake Air Temp). I wouldn't think it would cause this but crazier things happened.
HELP ME FIX MY WAGON!!!!!!!!...please
:UPDATE:
I have fuel and spark, although the spark seems kind of weak. I checked my wiring again for posterity but if I'm getting fuel and spark the wiring should be correct right?...Right!?! I guess i'll try a different dizzy and see how that goes. Unless anyone has any suggestions.

Did you wire in the resistor box? Or get saturated injectors? A bad Iat can make the car act an ass.

I have the resistor box wired and it is the one that came with the injectors so i'm assuming peak and hold. I need to just get off my ass and pull the rail, the fuel pump primes though.

Hard to diagnose wiring without a car, you can bring it by the shop next week if you like.
