P0200 Injector Circuit Malfunction

i just changed the whole top of the motor: heads, F90/90, injectors from 28 to 42, fuel rails.

then it my ses light came on and showed P0200 Injector Circuit Malfunction.

what caused this? is it b/c i went from 28 to 42 lb injectors and can it be tuned out. or is there electrical problems

What was it? It really bugs me when a problem is solved, but no details are given. Why? Because using the search feature then have to make a new thread, and that puts everybody else's panties in a bunch.

When I got that error on my Vette is was because one of the injector wires and rubbed and somewhat exposed the wire. Wrapped it up and it was good to go.

my guess would be a short in the circuit. Make sure you didn't pinch a wire or anything and that you got all of the injectors plugged in properly.

everything seems t be working but code is still there. it won't clear. number 4 spark plug looked as if it wasn't getting fuel. we messed with wireing, its good. we pluged it back in and the injector started working. spark was the same on all cylinders (used a spark tester). with this code the truck won't set fuel trims either.
