So i'm out of ideas and completely lost on whats wrong with my FD now and I have about a week to get it running due to my wife recently starting school and my work i need a running car BAD.

So first with my mods:
power fc and commander
downpipe, hi flow cat, apexi catback
intercooler
intakes
radiator

So ive never had problems with the car starting or running, I changed the radiator about 3 weeks ago and after that the car would start for 4-5 seconds then stall. So last night i changed the fuel pump and fuel filter thinking it was a fuel cut making the car stall and that night the car started for about a minute then stalled a total of 3 times. My map sensor is not messed up so i know its not that. So today i dropped my power fc in for the first time and reset it to the base map and when i tried to start it the car would only crank and crank but not fire up. Any suggestions on how to fix it would be helpful, just need to get my car running so i can take it down to Neptune Speed on the 28th for a tune. Running out of time and options someone PLEASE HELP!

Try putting back the stock computer back in and go through the deflooding procedures. if you were starting for 4-5 seconds and then stalling, it could be easily flooding. Make sure to check all your relays and fuses too.

you could also try some hotter heat range plugs to get you going if you are indeed flooding.
try the stock bur7eqp and bur9eqp plugs if your not using them already.

oh, forgot to ask if you had charged up your battery. never hurts to have it fully charged before you start cranking it over.

did you do anything to your clutch by any chance?
maby check your clutch switch - your clutch may be applying pressure to the flywheel and stalling you.

Try resetting the idle on your pfc to a much higher idle speed. Maybe 1500 ish. If that will keep the engine from dying, at least you can get it to the tuner.

Well the car won't even start with the PFC. Will changing the idle get it to start and how do I do that from the commander?

You said this all started after installing a new radiator... Have you rechecked your work do see if you did something (on accident) like damage the CAS lines, knock a ground wire off, etc?

FFWD_FD

did you remove the bumper to work on your radiator? did you remove the grounded wires mounted on the front support beam? check to see if the ground wires there are securely connected.

I didn't remove the front bumper but ill double check ground wires. Does anyone have pictures if what wore I should exactly be looking for?

With the stock ECU in place, have you looked at stored fault codes?

USMChris93FD

I'm nor throwing fault codes. Update: after trying to start with PFC there's a sound from under my uim that's sounds like light buzzing or electricity?
