fuel issue?? maybe?
A co worker has a 93 f150 with a 302. He said it has good fuel pressure from the pump. He has good fire but is not getting fuel from the injectors. What will cause him to have no fuel?

I would ask him if he has actually checked to see if he has fuel pressure with a guage. You can hear a fuel pump run, but doesn't mean it's actually delivering pressure. If you can post back with his fuel pressure numbers maybe that can help us.
Has he checked for codes or has the CEL come on with a DTC?
Could also be a short in the injector wiring harness. If he can pull a connector off of one that is accessible, have him check power from the Injector vehicle harness connector. Should be greater than 10.5 volts with key on.

Have him pull code's with engine off, since there should be something there in continous memory.
Have him use the method here to pull codes.
