What all have you checked? Did you make sure the main injector harness is snug? Have you done anything with your ECM recently?

just for the hell of it i swapped chips to see if it would make a difference the truck started and ran for about 10 minutes then died. same problem spark and fuel to fuel rail but does not run.

Re: my injectors may not be firing

If the chip is installed correctly, and you definitely have both spark and fuel pressure, your ignition module is dead. A bad ignition module won't generate a reference pulse preventing the injectors from firing. Part number is 1048-2827 (located under your distributor cap, BTW).

Is the chip right for your injectors?

Thanks that was the problem.
