I have a 1988 F-150 300 - six cyl engine, fuel injected, 4WD, manual tranny, pickup truck.
I'm not getting fuel to the engine. I *can* hear the fuel pump in the gas tank run.
This could be gas line freezeup, because it was bitter cold when it quit running. I was going down the highway about 50mph when it just quit. This was after driving about 40 miles. I tried to restart it, it started and ran for a half minute and would not start at all after that.
The gas tank was half full, I poured in 3 more gallons just to be sure the gauge was not stuck or wrong. It WILL run for a brief time when I pour some gas in the intake, so it's not electrical, and definately IS a fuel problem.
Someone said that some of these trucks have a second HI-Pressure fuel pump on the frame, under where the drivers feet are inside the truck. (plus the one in the tank). Because the truck is not here, I can not check, nor do I really know what I'd be looking for. I cant understand why it would need TWO pumps.
I looked on the web, but could not determine if it does, since most of what I found was pretty generic info, or for the wrong year truck. Is this possible? Why would there be 2 pumps, and what does it look like if there is one?
Thanks for all help.
