EFI Injector help
When I picked up my 1991 EFI Sammy, the injector was not putting out fuel. I did all the normal checks, Fuel pump, lines, etc...
Turns out there was no power at anu time to the injector.
I cut the wire that goes from the ECM to the injector , and ran a wire from the injector to a fuse that is controlled by the ignition switch.
This machine runs like a raped ape. I really don't know what this has done to fuel mileage because I only run it off-road, although I have road-tested it.
My question is,--- Am I harming anything, This is bypassing the ECM.
Yes, the check engine light is on. Since this bypasses the ECM, why does the injector still know how much fuel to put out? The engine runs well at all rpm's.
