Thank you Mopar1973man for the lead on the ECM PCM. I sent them out this morning.

Can I add resistors to the tans wires that are left over from the swap? I have have 2 connectors left over 1 is for speed sensor and the other is a circle connector that plugged in right above the pan. That I assume is for all other codes.

Thank you for the reply. I sent Auto Computer Specialist an email regarding the ECM PCM. Do you think the sender is the culprit? because when I i am at 1/4 tank its limp mode does not matter what gear I am in. But I can leave the truck running at the fuel station fueling up and the problem is gone until I hit 1/4 tank again. I am lost on this one. Could the sender hit 1/4 tank and send a problem signal to the PCM? I do have codes from the swap. P0500 from spinning tires in the snow. P0753 P0713 P0720 P01763 That's all the codes I came up with via the ignition trick 3 times. Thank you again for your time.

Recently converted my truck to a manual NV 4500. With the conversion we found the truck would go into limp mode (2000 rpm max before dead pedal) if the tank is at a 1/4. Truck runs perfect otherwise. Tested it today with running it down to 1/4 tank and did not have the issue until it was powered down. Thinking it maybe an electrical issue from the float assembly to the pcm. Fuel pressure is 15 psi solid. We also noticed today when fueling that the fuel remaining should have be appox 8 gallons, but the tank only took 22 gallons, it should be a 35 gallon tank. Previously we tested it by being at a 1/4 tank and going to the fuel station, we left it running and fueled, as soon as we started driving the issue did not return until we were back at a 1/4 of a tank. The tank does have a sump system instead of a draw straw. Additional info: The only other time it is in 2000 rpm limp mode is when it is initially started until I change gears. No issues when the truck was still an automatic(48RE). ECM was remanufactured, pcm is the stock auto. Contacted several places and have been told they will not issue me a manual PCM because of VIN. Any ideas?
