Hey guys. I've been having some major issues lately with my car and I haven't been able to drive it for almost two months now and it's possibly the worst feeling ever but enough of that. :frown:

I recently rebuilt my single jingle and painted my engine bay at the same time. Leading me to unplug mostly everything in the bay to be able to sand and paint. Once I rebuilt the motor, I installed everything back together and started it. Everything seemed to fire up correctly after some tweaking but when I tried to drive it, it won't accelerate at all. I slam the pedal to the floor and nothing. Cable is connected and tight but nothing (throttle door opens). There's fuel to rail and injectors, with a brand new fuel pump. ECU throwing no codes. Compression down the block is fantastic, all in the 180s with significant difference between cylinders. :wtf2:

After getting very frustrated I bought another KA24e(has emission delete) to see if maybe I rebuilt it wrong and the exact same issue still pertains which leads me to wonder if it could be the drivetrain? electrical? :gotme

I've switched ignition coils out, dizzy, maf, tps, 02 sensor. MAF and Throttle body have been cleaned so I highly doubt 2 different MAF that have been cleaned can cause a problem. I'm leaning towards the ECU being the issue in which I'm guna try out another once I can get my hands on one. Do you guys think I may have plugged something in wrong or left out? I have checked over my work several times and everything seems to be just dandy. :ohno:
