Is it a solid light when you have the jumper in to test the code?

fuse 14 (alt sig) under the dash its a 10a fuse take it out dont test it or even look at it. Put a brand new one in it.

This same thing happened to me on my ef a couple of years back i tore my hair out trying to fix it.

turns out the fuse had a small hairline crack in it so minute it would even test good. but once you went to start it then it would expand and break the connection.

Took it out replaced it and started right up.

A tell tell sign is if when you turn on your car then these lights would be on

Oil light, Batt light, check engine light.


Try this out

it should be the alt signal fuse AKA fuse 14 it tells the ecu that a alternator is present and it is ok to start the car basicly. Its just one of many in the PMFI fuel system. Thats about all i know.
