Make sure that the fuel vent hose and fuel tank pressure sensor are routed above the crossmember and brake cables. Damage to the fuel pump assembly can occur.ĬAUTION: Correct routing of the fuel vent hose and fuel tank pressure sensor is critical to fuel system operation. CAUTION: Do not support the fuel tank directly beneath the fuel pump mounting area.

Install the vent hose to the fuel tank vent spout.Ģ. Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxġ. Disconnect the fuel pump electrical connector.ġ2. Loosen the clamp and disconnect the vent hose from the fuel tank vent spout.ġ1. Remove the rear LH and RH sway bar bracket nuts and lower the sway bar.ġ0. Remove the fuel tank front and rear support straps and lower the front of the fuel tank approximately 25 mm (1 in). Note the routing of the fuel vent hose at this time. NOTE: The location of the fuel vent hose is critical to fuel system operation. Position a suitable jack under the fuel tank.ħ. Damage to the fuel pump assembly can occur. The 5.4L 4V engine is equipped with a return-type fuel system.ĭisconnect the vapor hose and the fuel hose(s) forward of the fuel tank.Ħ. NOTE: The 4.6L and 5.4L (2V) engines are equipped with returnless fuel systems. If equipped, remove the fuel tank skid plate.ĥ. Disconnect the vapor hoses at the rear of the fuel tank.Ĥ. As my siggy says, I'm not responsible if you break something. Should apply to 04-06 as well, but don't guarantee anything.

no.ĭo you still have your owners manual? it may give the location in cryptic code of where the inertia switch is.This applies to a 2003 Expy. I don't know where the fuel pump inertia switch is in that model. but it will probably have too much fuel pressure to operate the engine without screwing stuff up. PIN 2 wire negative is BROWN/orange.ĭon't forget that this electric fuel pump is variable speed controlled you can power it up directly to test it. pin 4 wire positive is PINK/black stripe. is this one up above something in the rear of the truck. i recall that those had an issue with corrosion also. probably a white wire but i am only looking at the wiring diagram you got pm'd.

you should have power on pin 5 at the fuel pump driver module.
so key on relay pinched to close the contacts for testing.
the inertia switch feeds pin 5 on the fuel pump driver module. Any kind of help is greatly appreciated thank youįuse F1.12 feeds the fuel pump relay contacts. Only other thing I think might be the problem is Powertrain Control Module but I honestly have no other idea. 24 or so volts.Ĭhecked the fuses and even disassembled the fuse box to get to the non servicable fuel pump relay to see if it had burnt out but it looked fine and also did a continuity test since I know no other way of troubleshooting that relay because it soldered on to a board.īut I think the relays and fuses are fine since I'm getting some type of reading. When straight to the fuse box found the green/yellow wire which i believe is the line driving the fuel pump voltage and also get a max of about. checked the positive line of the connector and have no voltage going through.Ĭhecked Fuel Pump Driver Module white wire which comes from the inertia switch which we bypassed to also see if the problem was the inertia switch and I get a max of. We began diagnosing from the pump and working our way to the fuse box.įuel Pump does not turn on for the few seconds it should to prime the vehicle. The fuel pump is brand new and also the Fuel Pump Drive Module is brand new and the car starts if you put starter fluid which means it is a fuel pump problem. Hello there is a ford expedition me and my dad are trying to fix for my aunt, but we cant seem to find the problem.
