For some reason my car keeps blowin ecu fuses. My grounds all look good and my stereo stuff isn't shorting out. My fuel pump doesn't turn on either and as soon as the car is in the on position it blows. The car still cranks when it blows though. Any suggestions??

Also the check engine light is constant and won't show a code when I jump it.

it has to be a bad ground or something is touching that shouldnt be im not for sure tho.. my old integra was super slammed and it kept blowing ecu fuses when i put in reverse and we could never figure it out. i parked it for a while and one i day raised it up a couple inches and it never blew another one lol.. but good luck man wiring problems like that sucks!

Check the main relay for a short. Also plug the main relay back in and unplug the IACV, fuel injectors, O2 sensor, or EVAP purge valve to see whether the fuse stops blowing.

thanks for the help. i tried to start my car today with a new fuse and i toasted my underdash harness. i think its about time for a new one.
