Fuel pump question

[Skman]

Just to update:
Took the truck out today and gave her a workout and it didn't throw a code at all. EGT also was lower again. So the fuel issue seems to be fixed now.
Unfortunately now the autoshift is acting up again. Mechanic pulled it outta the shop to test drive it and the splitter/range wasn't working. Would only shift 2 gears at a time and wouldn't go past 10th. We got under and tapped a couple sensors and pushed in the plugs. Then it worked fine.
Now today... it gets to 10th and you have to manually take it to 12 or its hangs up in 11th and the speedo stops working. Also, does this at 13th...need to skip from 12 to 14th or it hangs and speedo stops.
I'm gonna look at it this weekend. Hoping its just a bad connection at the output speed sensor.
Ugh..this truck.
