Thank you for that information. That helps me narrow the problem down quite a bit. I will concentrate on a fuel pump(s)/sender issue now.

Those Ford instructions are horrible. No need at all to touch or remove the SJB cover, etc.

You must first remove the subwoofer. When re-installing use a small punch in an adjacent hole to help you align holes and get screw threads started. Small perimeter panel around parking brake needs to be pulled straight up to remove.

But honestly, I don't think you are looking in the right place in terms of probability. You should be removing the front right passenger wheel well liner and then examining and diagnosing from there - where the control modules are. You can also directly access the fuel pump wires and do all of the test you wanted to do under the console. I highly recommend that you start there before going into the interior as there is much more to learn/diagnose/confirm in that location.

I’d also suggest checking or swapping the fuel pump module relays in the fuse box below the stowage latch - we’ve had relays go very sticky on cars which have had little to no use.

+ 1 .. I see you mention the fuel pump fuses but did you swap out the 2 fuel pump relays? mine have failed twice..

You can also by pass the fuel pump driver control modules to make the run constant on for a volume check . disconnect the line a the fuel rail and pump into a container..

also , did you check for a plugged filter ??

Yes, I did swap out the fuel pump relays and no change. Also, did verify fuel pump was not clogged. Thank you for your suggestions.

I know the GT guys told me you can bypass the Fuel Pump drive modules to run the pumps, They have used this method to drain old fuel out of the tank

Possible rodent nesting in the right side front fender and fuel level circuit chewed on. These codes are memory faults. Can you clear them and perform key on engine off self test ? The KOEO will be a hard fault and that would be the code to perform pinpoint test on. If you do that and post the code I will copy and paste pinpoint test directions for you. Hope this helps.

Not sure how to perform a KOEO test. Have googled for information but all links seem to indicate that you need to let the engine warm up prior to testing. This GT will not start, I will do more research on how to perform this test on a car not running and get back with you. I do appreciate the help you have offered.
