Codes
I have a 1998 2500 4x4 Quad cab. So far I have replaced the pump, lift pump in the tank and fuel lines. It ran good for about two weeks. It started acting up and the codes(p0122, p0121) came up. I replaced the TPS($350) Now I am getting two codes p1693 and p1689. The truck just cuts off while driving down the road. Thanks for any help. Phil

P0121-Accel. Position sensor volts do not agree with idle validation signal.
P0122-Accelerator pedal position sensor (APPS) signal votage to low.
P1689-No comminication between ECM and injection pump module.
P1693-DTC detected in PCM/ECM most likely the ECM.
There ya go. When the truck cuts off does it stay off or does it come back on? If you need anymore help let me know.

More like a fuel death. I checked the conn. at the pump ans EMC. I also check the grounds for loose conections. I reset the program to stock setting. I have a superchip with the truck.

I had a bad connection on my chip where the wire taps into the VP44 wire. The company sent me a new tap and it works great after I changed the tap. Mine would cut out like the switch was turned off but it would come back on its owen.
