[QUOTE="Roush6018, post: 16962140, member: 78571"] this is good results. the ECM is controlling the fuel pressure. it sees the fuel rail pressure sensor and it adjusts the voltage to the fuel pumps using the fuel pump relay and fuel pump driver module. i am going to hope the actual wiring is in good shape and not broken. i would recommend you replace the fuel pumps as a set and then recheck for the problem. if you replace both pumps and same problem happens. you need to verify the FRPS sensor has power and gound at the connector. verify the sensor is giving off a output voltage. then verify the signal wire is good from the FRPS to the ECU connector. then verify the ecu is recieving the FRPS signal voltage. verify the ECU has good power and ground. if all the above wires have checked out as Good. i recommend getting the ECU rebuilt/repaired at G7 Computers in new york, very quick turn around not waiting forever. if there is a problem with the actual wires then you need to fix the wires and recheck for the problem.
