Starved for Fuel

[BigRedWeather]

My truck has run on Jason Crawford's V1 Vegistroke WVO system for 130+K miles. It was starved for fuel recently be a dieing electric MSD diesel pump. After replacing that it ran like a champ again. It is starved for fuel again, so I put on a new MotorCraft Pedal Position Sensor (PPS) PN# DY967. No improvement. I left the PPS plugged in, but removed it from the pedal and actuated it by hand. The engine got no more fuel. Makes me think the new diesel pump has gone bad, very very quickly, or the device that receives the signal generated by the PPS is failing, and not passing the signal on to give more fuel.

Does anyone know the name of what receives the signal from the PPS? Where is it located. If I could replace that or the diesel pump, I might have this thing fixed. Any ideas?


Thanks,

The signal from the pedal goes to the computer. If the engine stays at idle. Check the IVS. Most likely the fuel pump is dieing.
