It is definately getting spark so I know the CAS should be good and my coilpacks and ignitor are good. And yes my power fc is turning on.

Here is an update: Tonight I swapped ecu with a friend. The only difference is the his is a completely stock sr20 and mine has 550cc injectors, 300zx maf, and 2871r.

1) Here is what is confusing me. I checked to see if he has power to the injector plug with my power fc and there is 12v power. But then I unplug the ecu and check the 12v power at the injector and there is still power. So where does the injector get its 12v source from. Obviously not the ecu. Ecu probably just controls it.

2) Also my second questions is that if a power fc tuned for a bigger setup than stock, will it still somewhat run on a stock setup. I couldnt get my friends car started with my tuned power fc. I dont think this is really relevent. I really just need to figure out where the injector gets its 12v source from.

Anyone know? My car is a 1995 s14.
