Resistors maybe?

Alright I took the resistor pack from the 4g63 to make them low impendence. Before i installed it my car ran fine and the reason i decided to switch to that is because i had a bad bearing. So i threw 450 and the resistors in there and SFMU and SAFC and went to turn it over and it didnt crank. Turns over and over. Could this be a faulty resistor pack, Bad injectors? We checked the CAS and CPS all good. My friend who works on 4g63 wants to say that its the ECU. I might have wired the SAFC wrong. I need some suggestions? Car has been off road for awhile and is just sittin there rottin away
thanks

Ick... unfortunately you did the one thing that makes troubleshooting ten times harder: install too many new modifications at once!

I would suggest very carefully double checking your S-AFC wiring and the wiring to/from the resistor pack. If the car was working before, I doubt one of the sensors suddenly died. Improper S-AFC or resistor pack wiring is far more likely.

Barring that, double check that you have the S-FMU installed the right way. You did remove the stock FPR, didn't you?

Sorry it took so long to respond. Yeah i took the SAFC off and tried it and still nothing. The stock FPR is off. If it was the resistor pack would it turn over and not run?

Yes it could still turn over but not fire the injectors.
