pcm - plug c1 issues

I recently sent my ECM off to be repared. Once it was installed, there were still issues with getting it started and staying running. the ECM repair technition told me I have issues with fuel delivery. I have narrowed the problen to PDC fuse #3 (circuit A14 RD/WHT) thru the wiring harness to PDM 1 on the firewall.With everything plugged in my test light lights up when I touch #3 fuse "blade". I can unplug connecter 1 at the PCM and the light goes off. The same circuit will also branch off to the connecter and connect to the ECM wireing harnedss which powers the lift pump. I have been able to get it started but will no stay started.

I think there may be an issue inside the PCM????
Right now the ECM is unplugged along with connecters C125 and C126 only 1 battery is in it with ground hookd up. there are no fuses or relays in the PDC (I jumped fuel system relay to complete the circuit to be tested) O
Once that issue is corrected I can continue to check "downstream" of C125 and C126
Any thoughts or suggestion need to correct/fix this issue will be greatly appreciated.

New lift pump and new injector pump. Injector hot wire test will get it to run.
