Sometimes the engine is electrically isolated because of motor mounts so there has to be a ground strap connecting the engine to the frame. Depending on where your battery ground is connected, and where you connected your jumper cables to ground ????
try spraying some carb cleaner into a vaccum hose and see if it will run. If so then you have ignition but no fuel delivery. If not then you have an ignition problem. make sure you hear the fuel pump hum when you turn the key to the run position. It should run for +/- 5 seconds then shut off. remove gas cap and listen for fuel pump operation through the fill hole. If you can hear the pump then you have a fuel injection issue. If the engine starts and runs for a few seconds then shuts off then you can suspect the crank or cam position sensor. The fuel pump runs through the oil pressure switch which could also be an issue.
Are you able to start the truck with application of the gas pedal?
ok well this is where you might be incorrect... either you have a 12 volt wire bleeding scross or you have a bad ignition switch. the run wire off the ignition switch is the only thing that will keep it running unless you have a remote start then of course that could keep the engine running. you might want to start by making sure the ignition switch is beaking the signal to the PCM.
Locate the fuel pump relay by looking at the inside of the fuse box cover or the owners manual. Remove the relay and see if the pump stops. If it does, then locate another relay in the same fuse box that has the same part number on it and is not required for engine operation like a wiper motor or AC control relay. Install that relay in place of the fuel pump relay and see if the pump continues to run. If it doesn't then start the engine to verify proper operation. If it runs OK, then shut it off and check to see if the pump is still running. If it's not still running then replace the fuel pump relay. If it still continues to run then the most likely cause is a shorted wiring harness. The harness usually runs along the floor board and can short out by making contact with the vehicle body. As for the steering column, try this if the gear selector is on the column. Grasp the selector lever and pull up on it while trying to start the vehicle. If the vehicle now starts then column linkage is worn, a common problem with ford column shifters.
the pump is part of the filter/separator not in the tank no fuel will come out if filter is removed make sure there is fuel in the upper filter if there is the pump is ok it might be an oil pressure concern
