Further, since more power can be obtained from a lighter motor, our fuel pumps are lighter, and they can provide more flow than a similarly sized fuel pump with a brushed motor. I highly recommend getting a repair manual for doing this job. Any chance you might have reversed the power and ground leads on the motor? Are you planning to just replace the pump or the whole fuel pump assembly? Good luck If he has two working keys, he could attempt to reprogram the now bad key. You are going to have to drop the gas tank, the fuel pump is an in-tank design, with fuel level and pump all as one drop in unit. Check inside the cab on the pass side about 18 inches up on the firewall.
As you said, the biggest drawback is the heat that is generated, and being submerged helps the pump run cooler. I went looking up near the dash, until someone told me it was located further back Most fuel pumps are located in the gas tank. All Replacement items are backed by a 1-year, unlimited-mileage warranty. The reason I suggest a test light rather than a multimeter is the input impedance of a multimeter is very high and won't load the circuit. Notes: Fuel Pump and Sender Assembly -- Seal is attached to flange; Fuel tank contamination is the leading cause of premature fuel pump failure. By chance have you checked for fuel pressure at the fuel rail with the new pump? I would suggest unplugging the inertia switch and using a test light to check for voltage to the switch.
Bought another 2000 Sport God help me , 4. I don't see a listing got the vent hose. This results in much-increased pump life. I found this for the dimensions of the filler hose - 22. Also when you turn the key on you can feel the relay clicking in. Bought and installed a new sensor, never had any running symptoms with the bad one.
One side goes to the tank, the other side comes from the truck First I put power to the fuel pump using a jumper box or car battery. . How can i determine if it is a problem with the fuel pressure regulator, fuel pump or sensor? Added problems for submerged pumps are encountered with diesel fuel: brushes are adversely affected. Cooling the pumps is the reason auto mfgs mounted them in the tank. Ever since I replaced the fuel pump it starts up instantly every time.
I didn't see any listed anywhere. Imp, thanks for the kind words. Brushless pump motors are gaining ground. No, they covered that possibility. If that doesn't do it check the wire for breaks.
Sure I live in Jersey where the part came from. The Ranger pump failed at about 60K miles, which was way too soon and that's why I cut it apart. Under normal conditions, that relief is always closed. Moving that extra fluid uses energy and creates heat, but is necessary by usual design methods. Jered, glad you got it fixed! This replacement item is thoroughly patterned after to work like the genuine fuel pump mounted on your car or truck. The supply current may be too low to give a meaningful voltage measurement at the output terminal, although that would seem somewhat odd. There is a metal cover that should be unscrewed … then the top of the gas tank also has a metal cover.
I've seen many posts of premature failures on 04s particularly. Well first off, are you sure its the Fuel Pump? If the inertia switch were shorting that line to ground through the fuel pump you would measure ground potential on that wire. I told him the second time isn't free. Even when the website stated it would be shipped next day. The cost was a little more money. You could try changing out the fuel filter in case it is just resisting flow, but with the age the pump's probably worn out.
Why they were even employed, I dunno. I'm learning more about fords everyday. On the 98 and newer Escorts, access to the fuel pump is located under the rear seats. Once I receive both hoses I will post about my findings. I got it the next day after paying an extra 20. Will do more testing as you suggested.
Please be aware that the '04s do not run at constant speed. Jered, glad you got it fixed! You'll probably see something less than 10 ohms but probably more than 3 ohms. The switch won't cause low voltage on only one terminal. I carefully cut the clamps off with my Dremel tool with a thin cutting wheel. I cut the fuel line past where the break is where it straightens out to run horizontally along the frame. If only the pump, you can save a lot of time and aggravation by taking a few short cuts I've learned.
