98 5.7 no fuel

I just replaced my engine in a 98 z71 5.7 with a complete used 98 5.7 with 11k miles on it. it runs fine if I pour gas in air intake the fuel pressure is 62 psi I can hear the injector making noise when I turn on the key, It will not get any fuel and run. Anyone know what it could be? I have triple checked all wires and grounds.

Re: 98 5.7 no fuel

So you have 62psi at the rail, but the injectors arent opening?

I would check to make sure you have crank and cam position sensor signals making it to the PCM.

Do you have a scan tool to watch data streams? Are there any codes stored?
