Having problems with your 1999 Ford Super Duty F 550 ?
Fuel pump does not work- 1999 ford super duty class a motorhome
\015 I have a 1999 Aerbus motorhome on a 1999 Ford Motorhome class A chassis with GVW of 20,500 and a V-10 gas engine. The fuel pump does not work, the vehicle has 16,000 miles, the fuel pump shutoff switch appears OK and the 'fuel reset' light is not on. I have checked the fuses, replaced the fuel filter, and verified the lines are clear bact to the first howe out of the tank to the stailness steel fuel line (blue) but since the pump is in the tank and requires removal of the hydraulic jacks to remove the tank, that is my last resort. I want to check the power to the pump but need the correct wire color to the pump to verify power. Can you point me in the right direction\015
Check your vehicles safeties. Your ECM is probably programed for engine shutdown if it senses low oil pressure or low coolant level. Do a preliminary check.
I have been a mechanic for 15 years and have worked on alot of motorhome fuel pumps. 99 percent of the time it is the fuel pump that is bad. if you are getting power at the fuse you more than likely have a bad pump. I understand the thing about the hydraulic jacks they are a pain in the ****. sorry I can't tell you an easier way.
