like the topic says, FI/ m/ underhood fuse keeps blowing when trying to start. bad ecu? short? or a loose wire grounding out somewhere in the wiring (checked many times over, will continue to check)?

jdm h22 w/ jdm p13 in ek, btw
Any insight is much appreciated

a friend of mine had a similar prob, the guy that owned it before had a VAFC in it and when he took it out he didn't tape the wired properely.
just a suggestion.

what was the fuse on there, a 7.5amp? 10? could you try a 15 or 20? maybe 20 is too high, but just a suggestion.

Don't put a fuse higher than what the factory suggest for the ECU. If it keeps blowing, then there must be a short somewhere. Popping in a bigger fuse, you're risking in shorting out the ECU itself.

yea, i thought about doing that, but that 15 amp fuse is there to protect that ecu...so i guess it looks like time to hunt for a short i used these as my o2 sensor plugs, would they have caused the short?

anybody know why else this fuse would blow? searched far and wide for that shorted wire and couldn't find it...

Well if you didn't find a short then its PROBABLY in the ecu...if you know someone with the same ecu change them out just to see or you can open yours and make sure something (like a screw) hasn't rolled on or under the circuit board causing it to short out.

i bet the injector wire is shorting somewhere. happend to mine once, was shorting on the intake manifold.

ok, i figured out the problem...i sanded down the areas where my ecu ground was grounded to and changed a couple grounding points in the engine as well as sanding the paint off the surface to where they grounded to and she started right up...
