Car won't start..EVO7
Hi guys, I'm new to this place, been reading for a while but never posted
anyways, My dumbass friend had my evo for a month or so, long story short, the battery died after a month's time, he bought a new one, and reverses the battery terminals and short circuited somewhere,
Now the ecu doesn't get power, so no spark, no fuel, no life !
The main + terminal's fuse burnt, I replaced it, then checked every single fuse in the engine bay and driver's side fuse box, all are fine !
the car has a power fc, I put the stock ecu back, same shiit .. what next ? help plz
thanx

is there electricity getting to the rest of the car? there must be a fuse that took a dump somewhere. Check the under the hood fuses and near the door fuses. I dont think there was a short circuit as much as reversing polarity off power on electrical equipment.
If you have the mitsu working manual of the car, it may help you in diagnosing the problems...check in the eletrical section. do a search for it.

Its not a fuse because the cars' electrical circuits are load to ground. You shot voltage the opposite way (electron theory LOL!). The ring antenna is on the steering column, and on US model evos (LHD) the immobilizer ecu is located to the right of the steering wheel behind the center console of the dash ( Near DLC), but I'm not going to tell you how to surpass it.
If power is present at pin 7( L/Y evo 8) and pin 9 (L/W) the ecu may be toast. If no power present futhur diag required. Good luck
Does the engine crank when the key is turned?
