Runs rough as in a steady vibration (light) but an even vibration, revs up however when letting clutch out to move it bogs down ( like the equinox you were trying to move that had bad fuel pump ) I have 30psi at idle and 40psi at snap on fuel rail. This all happened after removing engine to replace oil pan gasket, while there I also changed rod bearings and mains and put a melling high volume pump in and a new timing chain set, yes cam time is on
Attached are pictures of timing, wire issues and the corrected wire issues

The fact that one does not click could mean that that injector is shorted pulling down that whole bank, or the crossed circuit could have taken out the injector driver for that bank.
You can try disconnecting that one injector that doesn't click, then disconnect the battery and touch the terminals together to wipe out keep alive memory.
Then reconnect the battery and start the truck with the suspect injector disconnected and see if the other two come back online.

I'm wondering if the injector that didn't click was unplugged to front probe it's connector. Wouldn't be a bad idea to ohm out all 3 injectors though.
That test has verified continuity of the control wiring as far as S131. So the problem is likely a "tripped" or smoked ECM driver or an maybe an open between S131 and the ECM.

Thanks to another ScannerDanner video I'm not a parts changer
I included a diagram showing my tests at PCM

Let us know when it's up and running. I had a first generation explorer for many years and still have a soft spot for them.
