Starts up only drivers side firing

First post. Truck lost all power but made it home on 4 cyl. Scanned it and got the following codes:
1280 ICP C/low (oil on pigtail of ICP)
1282 ICP higher than desired
1211 ICP higher/lower than desired
1249 wastegate control valve
1670 Electronic feedback signal not detected

B1302 Accessory delay relay coil circuit failure

What I've done so far.
cleaned out ICP and reconnected no change.
unplugged ICP no change, except for SES coming on and cleared once I plugged it in.
I have an AE scanner with the ford package I used it to check oil preassure while cranking and it is reading above 900PSI, 2200PSI while running
Did a buzz test to injectors and all worked and passed test.
Unable to complete contribution test but the passenger side bank is not firing at all. Checked by temp on exhaust manifiold. Drivers side all firing.

Currently engine will crank right up cold and idle roughly. Will eventually shut off and then cranking it up takes a lot of effort.

What it has. boost valve, chip 6 pos. 4 inch exhaust and cold air intake (dry).

Batteries are new and checked no voltage issues.

Any help will be appreciated.

There is actually a common issue with the UVCH plug on our trucks. BUT, I don't think you'd have a good "buzz" test on the bank that's not firing.

So, you've got to explore some of that.....

Do a Search on UVCH, there's LOTS of talk on this. Also, it could be the IDM itself. They are sometimes found wet because of their location (behind the drivers wheel well, kinda right behind the Fx50 emblem on the ft fender) and otherwise can just fail like anything else

All-in-all your problem sounds electrical despite your "fuel" codes (+ the P1607 "IDM Electronic Feedback / EF signal not detected Open/shorted EF circuit)" so, I'd start there.

Also, cleaning the oil off the ICP isn't really "fixing" anything. The oil isn't the problem, it's just an indication of a leaking seal in the ICP and a sign it's failing.

Checked for continuity on the harness and it passed but I've also read that it may still be bad. I did suspect the IDM but have not checked it. Plan on replacing the UVC harness.

On the IDM it does not look bad and a place in Florida called Computer exchange are only 130. ish

Thanks for the replys I do alse think it is electrical. Will dig into it tomorrow and post back.

HELP!!! right side of motor not firing

Ok,

I replaced the right valve cover harness and wiring. Cranked it up and still not working, passenger side is dead. While running there is oil coming out of the injectors but no heat at exhaust manifold. Right side is dead.

I also unplugged one of the top oil plugs on the rail to see if oil was flowing and while cranking oil flows out but not with much pressure. I did not get it to crank with the plug removed. Using the scanner the pressure was above 800 while cranking. Over 2000 when it runs(even though it is missing on 4 cyl.)

I checked all wiring and although old and showing some signs of wear it does not look chafed or broken. I would like to rule out the IDM and or wiring short.

How can I check if the idm is working?

Checked fuel pressure today and it was low, fixed it and now it is right at 95 PSI idle 94 WOT.

I was able to do a contribution test and found 2 new codes
P0275 cyl 5 balance fault
P0284 cyl 8 balance fault

P0541 intake heat
P0640 intake air (I do not have an air intake heater)

Duty cycle KOEO IS 14.84
Duty Cycle KOER is 10.94
ICP is 524 idle
ICP disconnected is 724.04

Passenger side is still not working as it should. Temp on exhaust is low 120 to 150 and truck improved with fuel pressure correction but it is has no power.
