Hello all! I have an 02 ML320 which stalled while driving and now will not start. Although it was changed recently I replaced the CPS. Still no luck, I have also replaced the ignition switch as it seemed to be sticking in the start position. There is no fuel pressure and the pump will not cycle. I do not get a start error. I have tried a jumper direct to the green wire on the connector in the left wheel well and it will turn the pump on and run for a second and then die.I have tried a jumper at the K3 relay, I get power to the fuel pump fuse but nothing at the pump or connector. I can not seem to trace the wire from the Fuse to the fuel pump.Does anyone know of anything else between the two that could cause this? Also when I try to start The Fuel pump relay does not engage (no signal from ECM?) From my wiring diagram i do not see anything between the fuse and the pump except 1 connector. Any help would be greatly appreciated.
