diag.net/file/f74gt2azy… Here I'm on Pin one at C3239 and the other lead is one the same wire at the PCM (pin 40).Смотреть что такое "fuel pump driver module" в других словарях:įuel injection - Fuel rail connected to the injectors that are mounted just above the intake manifold on a four cylinder engine. I get it back to the shop and start doing some brake torques in drive and reverse and I can see the signal break up. Scan data shows good fuel rail pressures throughout. I reluctantly take it on a test drive and there's a little hesitation an acceleration but it clears up and I can accelerate through it. I capture the event and proceed to cycle the engine on and off and it starts every time.
When I cycle the key I hear what sounds to me a slightly delayed fuel pump prime. I plug the FPDM harness back in so that I can check pins 1 and 3 that feed the modulated signal and driver command back to the PCM. It buzzes so I am good with that for now (I didn't check the actual fuel pressure when it was bypassed nor did I voltage drop the wires from the connector to the fuel pump I did however check and confirm power and grounds at the connector once the van started diag.net/file/f1c7qmpvd…). Jumping pins 4/5 and 2/3 at the FPDM connector give me direct power and ground to the pump. I then unplug the connector (C3239) diag.net/file/f72l56g3n… to the FPDM to bypass it so that I can check the operation of the fuel pump. There was no evidence that the case was compromised. The FPDM on this van is on the frame rail right behind the fuel filter. I'm familiar with the FPDM case corroding and causing issues and half expected to see this here since I live in the salt belt.

No fuel pressure on scan data and a P1233 Fuel Pump Driver Module offline code. I have a stumper on my hands and looking for direction.
