the car is an 84 gsl-se

only the rear rotor is firing

at first I could switch the injectors front to back and then only the front rotor would fire.

then I got rebuild injectors and now only the rear one fires even if I swap injectors around.

Spark is good all around

does anyone know how to troubleshoot something like this i.e fuel injection problems

I'm fairly new to rotories although I know the basics

If someone could just list things i should check that would be super helpfull

thanks guys

switch back to the old injectors and see if they work again if so then you probably got a short or something.

Check wiring..... check the fusible links cause there is one for the injection. Next check wire continuaty between the injector and ECU. The haynes manual has all the pins labelled. So it actually doesn't take very long....

Sounds like a bad injector clip. You might as well replace both of them while you have the uim off. They are a Bosch style clip that is found on many late model Fords. Some parts stores carry new ones.
