ecu fuse keeps blowing, please help

[nothingFancy]

i got a 91 240 hatch with redtop sr and 62 ecu

im stuck in this biggest jam ever and i ran out of ideas, car was running great, i shut it off to talk to some 1 and i go to start it back on it fired up then it shut off. then it never wanted to fire again. it keeps crankin and cranking, it keeps blowing the fuse underthe dash to the ecu as soon as i put the ignition on the on position. i have no idea y.

thanx.

Sounds like you have a short in the ignition ciruit. probably the splices over by the battery tray. You are sending too much voltage to the ecu and tripping the circuit. Check the splices for continuity and look for a bad ground on the ecu
