Alright my car has been down for about 2 weeks now because it keeps blowing a fuse. I would love to learn how to track down and fix this issue so any advice on diagnosing this and fixing it would be helpful.
- the car -
1995 sc400
mileage 300k+
- mods to the car -
hid low beams,
coilovers
wheels,
led taillight bulbs
- the issue -
keeps blowing the efi (electric fuel injection) fuse as soon as i turn my key on
the fuse is a 30amp fuse so i can't just put a bigger one
starter is clicking,
there is still spark,
no fuel is getting to the engine because this fuse is blowing
- tried failed fixes -
clean the battery terminals
Regrounded the ground wire that was connected to the battery terminal that i forgot to connect
checked and reouted the wiring harness that was under my driver wheel well
bypassed the fuel pump ecu incase my fuel pump ecu was going out
swapped out my fuel pump with the fuel pump from my parts car
quick timieline of car issues and fixes since i had it said:About 4 months ago I had hopped a curb and broken all kinds of things on the bottom of my sc link to the thread
I ended up buying a parts car and replacing the parts myself using jacks, an engine brace, and hand tools. Got the up and running successfully for a couple of weeks. Then I had an ignition interlock installed on it
Then a week after the ignition interlock was installed, the damn thing stopped working on me and I couldnt start my car for two days. Got another one and a day later I blew an efi fuse link to url
that problem was temporarily fixed by removing my foglights
Now the problem came back link to thread
This time the engine cut off when I floored it. The problem of the efi fuse still remains.
