Well heres the problem. I get into my car this morning and well it just doesn't start. My AFC doesn't cut on either. Well I got it to start one time but the big injectors made it lobby and then it cut off like 10 seceonds later. I checked the AFC and apperently the wires had been tugged and they werent connected inside. So I took the back cover off and sure enough the little plug that plugs into the board was off. So I plugged it back in thinking everything would be ok. NOT!! It still didnt cut on!! The car still turns over and everything it just wont cut on. Then after messing around a little and trying to start the car the battery goes dead on me. WTF!! The AFC guy said to check all the wires at the ECU but I really dont see how they could have come loose. Could my AFC be fucked up I also blew my ecu fuse twice (I guess because the plug in the afc was only half connected because it hasnt happened since I replugged it) WTF is going on

The battery going dead on me was wierd because I'm working an Optima red top that hasn't even been in the car for a year. "sigh" What could be causing the AFC not to cut on and make my battery die?

i don't know what's the problem, are you getting any fuel alt all?? I have a red top optima and it flipped over in my trunk yesterday and welded it's own terminals upsidown in my trunk while driving. It started right back up.. If yours died, it should be under warranty for like 5 years. those batteries are sweet.

I think the car is getting fuel but I think it cant start because its getting too much. I have 450s in and I'm pretty sure the stock ecu without the AFC working cant run the injectors without it flooding the engine.

try after cranking pull out a a spark plug then see if it is wet. If you aren't getting any fuel at all I would switch back to stock injectors untill you figure out what is going on with the afc. or get as close to 300cc. I have heard a stock ecu can handle up to 300cc without running to rich.

JD

well I would just move back to stock injectors but that isnt an option right now. My turbo is on and I'm running 9-10 pounds of boost. If I used stock injectors with no fuel management I would for sure blow my motor.

then get a new afc

Well of course that is an easy answer!!!! I'm like an hour away from home and kinda need to get my car home. Can the AFC really break just like that? I've never heard of one just breaking like this though. DAAMMMMIT this sucks!!! Somebody must have somthing to help me!!

check your AFC wire connections at the ECU, especially if you didn't solder them, they might just have came loose with the "tug".

When you say "the little plug that plugs into the board was off", do you mean inside the AFC? and not the outer wiring? If it's internal of the AFC unit, it sounds like when the wire was tugged, it might have damaged the circuit board. I would disconnect the AFC and examine to make sure all the contacts are still soldered on before reinstalling it.. you don't want to fry your AFC by fussing with it. Just pray your ECU or AFC isn't fried. Sorry to hear man.

Yeah I mean the plug actually INSIDE the afc. I unscrewed the back and it was right there. Everything inside appears to be ok although I'm no computer wiz or anything. It's pretty smart how they made the wires that go into the afc have a plug rather than being soldered on. Well I had to come home to get some tools. Off to see if I can fix this or not!! Anyone else have a problem with this??
