missing on cylinders 5 and 6

1990 5.0 misses on cylinders 5 and 6, spark appears ok, spark plug wires on distributor correctly. Could it be a fuel injector or injector wiring problem? New 42 lb injectors.

Yup...check the connectors for a pulse with a noid lite or a regular 12vdc test light between the pins. Engine running, you should see the light blinking. If it doesn't blink, suggest you check the salt & pepper connectors first and re-check....if it does blink....bad injectors are a possibility, provided there is not a cylinders compression problem.
