I only replaced driver side during the rebuild, but I'll be replacing both in the next few days. Do all the wires get brittle as fast as the Dormans? Is one better than the other?

Get ford wiring gaskets and sensors. All others are junk and don’t last.

So what's causing the idm to fry? You could have a pinched wire beneath one of the valve covers. I suppose you could ohm out the uvch's at the positive pins and other probe on ground and see if there is continuity. That would be a quick easy check to see if that's causing the idm's to burn, although I'd expect to see burns in the uvch connectors as well.

Should have replaced both valve cover gaskets. Chip, no chip it will start.

You have a short somewhere.

And thinking further, I suppose a solenoid could be shorted on an injector as well, so I'd definitely check my resistance on all 8 of them too.

Ok... got a new to me, very good condition engine wire harness. Pulled another IDM yesterday from a wrecked truck. I have the pin test for injection system from all data. Even though I dont have a DTC I figured it's a good place to start. Both valve covers are new, now, and all sensors were already replaced during the rebuild. I'll keep the updates coming as I make progress. Thanks for the ideas and places to start.

I hope the injector solenoids aren't bad, they're brand new with about 7 minutes of run time from Full force, 180/100

Everything is from reputable companies or motorcraft. I am trying to build this to last and be a little fun to drive as well... I'll have an update in about 4 or 5 hours on progress

Ok, wiring harness installed, valve covers inspected, again. All injectors checked good 2.8 ohms, ground for IDM plug is good, wiring harness ohmed from IDM plug to injectors, everything there checks out. I've got the wiring diagram for IDM printed. Everything is checking good. Any advice on what to check next? I think I'm going to throw the idm and pcm in without the chip, buzz test, self demand test, (hopefully) start and go from there
