I have a Ford F150 that just stopped running while driving down the highway. I replaced the fuel filter thinking it may be a fuel issue, since the spark plugs have a strong spark. When the filter was removed, the line was pressured up, and gas squirted out. After replacing the filter, I attempted to bleed the air from the line using the valve in the injector fuel line. I would turn on the key, hear the fuel pump run for a few seconds and stop. This was while I had the valve opened. I would only get a small squirt of air, and little gas. I did this numerous times. I disconnecte the line from the rear end of the filter, and turned on the key. I expect the pump to run continiuously and squirt gas. However, it would only run for a few seconds and only pump out a few drops of gas. The pump was changed six months ago. Shouldn't it keep running until the system is fully pressurized?

Welcome to the forum, At key on, no crank, the pump runs for a few seconds then cuts off without rpm signal, for the rpm signal to be present, the engine needs to be cranking. Use a gage and check fuel pressure.
