Yes -recheck all work done and test all components for power and correct operation
SOURCE: 1992 f-150 dual gas tanks tank closest to cab of truck pumps gas out the fuel cap
A FORD EQUIPED WITH DUAL TANKS THIS YEAR MODEL HAS CHECK VALVES IN THE FUEL PUMPS .THE FUEL RUNS FROM THE REAR TANK WHEN IT IS POWERED ON TO A TEE AND INTO THE SAME LINE AS THE FRONT PUMP . THE PROBLEM IS AT THE BOTTOM OF THE FRONT FUEL PUMP THERE IS A CHECK VALVE ON THE FOOT AND IT IS NOT WORKING.WHILE THE TRUCK IS RUNNING WITH THE REAR FUEL PUMP ON IT IS PUMPING FUEL INTO THE FRONT TANK . IT WILL RUN OUT OF THE NECK WHEN IT IS FULL.THE FIX IS SIMPLE REPLACE THE FRONT FUEL PUMP. THEY DONT MAKE A CHECK VALVE REPLACEMENT I CHECKED I HAD THE SAME PROBLEM AS YOU.

Check to see if timing belt is broken. or wiring to crank-shaft sensor and check sensor itself on front of flywheel typically but may be on side of block usually the further towards the transmission is Crank and closer to front is cam sensor.
Check relays by switching from others of the same numbers.
Crank-shaft positioning sensor is bad perhaps.
Remove plug under vehicle that leads to fuel pump and check for voltage when key is turned on. if voltage is there is either defective fuel pump, was put in wrong or is harness from that point to the pump.
try banging the tank with hammer as someone turns key on.
check harness from fuel pump to where it goes into the body - remove from body plug and inspect.
Should be either and or both a fuel pump relay and fuse!
Run 12 volts to the positive side of the fuel pump wiring to see if pump is good. 3 wires usuallly 1 is ground for both the fuel guage and the other positive for the pump. and other is positive for the fuel pump guage and these two wires for the guage will show some resistance. put a fuse inline with the 12volts to the fuel pump positive but cut the line to the body prior to this - temporarily.
Could be bad switch in ignition unit in steering column but doubtful.
Hope this helps.

Check your MAP and TP sensors. Your throttle body may be having trouble determining position and is compensating by adjusting RPMs.
