Do you have a DVOM(Digital Volt Ohm Meter)? We could do start some testing for a possible loose Under Valve Cover Wiring Harness https://www.ford-trucks.com/forums/8...light=cent+mod

Sure, that's a good electrical place to start, and I consider it preemptive maintenance to remove the valve covers and shim the connector personally. Another consideration is to unplug the ICP sensor in the front of the driver's side head and see if the idle gets better, without proper live data tools, to view ICP and IPR data, these are the only things I can think of right now.

ok well i was going to test and a guy said he removed the 9pin plug UVCH on the passenger side and it did not make a difference. So we removed the valve cover on the passenger side, but the 9 pin connector seemed just fine. We unpluged and pluged in back in and still did not make any difference.
We removed the 9pin connector off of the driver side and it would not start. Is there some control module that runs both sides?
Should i go rent a OBD II reader from a parts store to check out what the P1316 code is? Some one suggested its the PCM.
We left the passenger side valve cover off for the night. ( need a wobble head ext.)
Thank you in advance.

Your title now is not really helping us get too much help from others, If you go back to your first post and click the Edit then go advanced you can change your title, maybe others will chime in.
That said, If there is no change when you completely disconnected the UVCH on passenger's side there is an electrical issue that is shutting down that bank, I would try unplugging all the injectors on that side, plug the 9 pin back in and start plugging the injectors one at a time, to see which one kills that bank again, look for issues with wiring too, there is a module (IDM) Injector Drive Module that powers all of the injectors, but since you already have the valve covers off this would be an easy check.

Ok tonight i rented a OBD II from a auto parts store, $350 deposit, i hooked ever thing back up, it tells me no codes are found, this is the test with out the engine running.
I checked the valve cover gasket to make sure that wasn't the problem. It tested fine.
i checked the glow plugs and the injectors directly and through the VC gasket. They were both the same readings.
1.1, 1.1, 3.5, 3.4, 3.5, 3.5, 1.2, 1.1
Ps i did the quarter trick, worked great. Thanks for the Idea.
well my in-laws bought a PCM before i got it, and they said the connection on it look like it had moisture in it. So its going to be towed to a ford dealership to be programed. Is there anything i should do to check anything till its towed?

Unfortunately we could have told you most of the OBDII's will not work on powerstrokes.
With the Service Engine light on there is a code stored.
When you had the VC's off did you disconnect all the injector plugs, start it and try plugging them in one by one? There is something electrically that sounds(Through internet diagnosis?) that it is shutting down that bank. Thanks for changing the title I think it will attract some others for thoughts.

no, i forgot
. I lost my paper that I was writing on., but i can take it apart easy now that i have the right tools.
How ever i did unplug all of them and plug them back in. once all the wires were connected with the VC off i started it, didn't make a difference tho.
Tomorrow i will take it apart again and plug them in one by one.
Is there a way to tell if the 9 pin connector on the out side of the VC is sending power/signal?

In order to test the output from the IDM the easiest way would be with a BUZZ test with a proper diagnostic tool. Here is a test for the IDM wiring though that might help
