Had posted before that I generated code p0216 and the companion code from my ecm. I have been using the hypertech programmer, so I deleted the codes and set the ecm back to factory settings. I took the truck to the dealer to have things checked out. They charged me 63.00 to tell me they could not read the ecm because the codes were deleted. I had them check the pressure to the lift pump. 10 psi at idle and 5-7 psi at WOT. I,m currently at 57,000 miles so I have a bit of warranty to go. Not real sure where to go from here. Thanks.
