driving home from work about a month ago pedal goes dead replace apps sensor. drive to work does fine leave work just fine till a mile from home dead pedal again. reset apps good to the end of the driveway. back to the garage now with codes 1693 1286 0237 0236 0122 1475 0577. checked for broken wires and bad grounds replaced map sensor. started it up no bus and still no pedal. im lost

the pressure to the pump was good but i had no pressure at the head fuel just dribbled out and very hard starting i believe this was due to letting the last lift pump go to long and not having a guage at that time so i pulled and replaced the vp and put a new air dog system on. the truck ran great in the garage with throttle response as soon as i got out of the garage dead pedal. threw 0215 0122 1475 and 0236. so i started at the map sensor 4.87v then on to the pcm got nothin then on to the pdc more than100 ohms so im kinda thinkin ecm.

P0215 - VP44 failure - http://forum.mopar1973man.com/threads/2561-P0215-Fuel-Injection-Pump-Control-Circuit P0122 - APPS Sensor - http://forum.mopar1973man.com/threads/2556-P0122-Accelerator-Position-Sensor-(APPS)-Signal-Voltage-Too-Low P1475 - +5 Volts too high - http://forum.mopar1973man.com/threads/2623-P1475-Aux-5-Volt-Supply-Voltage-High P0236 - Map sensors too high too long - http://forum.mopar1973man.com/threads/2570-P0236-Map-Sensor-Too-High-Too-Long Well just looking at the codes P0215 requires a new injection pump. I'm going to assume the P0236 code is caused from the P1475 code that might just be a ECM problem. P0122 might be just a wore out APPS sensor but I would deal with the P1475 first.
