I have a 1989 Fleetwood Pace Arrow. It is a Ford chassis with a gas 4bbl Holley carb. The fuel pump (electric right in front of the gas tank) was replaced by the last owner because when I went to buy it the pump wouldn't work. Well I don't think it was the pump that was bad. I wasn't involved with the repair (you can tell the pump is new).
The carb. keeps running out of fuel. so I checked the fuel pump inertia switch. I tried to reset it. It was not tripped. (camper hasn't been driven in 2 years). I checked the voltage at the relay connector (unplugged) with the key in the run position .5-.8 volts. Same voltage with the key in the off position. Turn the main power switch above the door off. The voltage reading goes to zero in all positions. When I turn the switch to start (while cranking) the voltage bounces between .6-5.12 volts. Plugged the connector back into the relay and probed the wires at the pump. The results are the same. This tells me the relay is ok. I jumped the pump with a 12v battery and the pump filled the carb with fuel and started.
Something is wrong in the wires but I can't find a fuse or a fuel pump relay so I have no idea where the short or break might be.
I checked both fuse panels under the dash and under the hood. I know in cars there is a fuel pump relay somewere (under the drivers seat in a mustang). I think the relay might be bad but I have no idea were to look. I don't want to run a bypass wire I really want to fix it the right way.Can someone PLEASE help me with this. I have been pulling my hair out trying to fix this.
Sorry its so long but I wanted to give as much info as I could.
Thank-you
Bob
