Weird ground problem
Help, please,
I am working on an 87 Formula Firebird with a stock TPI. Problem is, someone put the engine and TPI in the car that has no idea what he was doing. I got the engine to start and it had misses on three cylinders. Replaced those injectors and picked up the three, but now I lost all cylinders on the even bank.
I tried a noid light and it flashes but it isn't very bright a I would expect it to be. If I disconnect any injector on the odd side, it picks up the 4 even injectors. If I reconnect the one injector, it drops the 4 even cylinders again.
I tried all the ground connections I know of, voltage to the injectors, another ECU, etc. but no help.
WHAT NOW???????
