ive got a 86 ford f150 fuel injected 5.0 pick up and itll turn over but wont start. ive replaced two fuel filters, put a new coil on it. im not getting any spark what so ever. i was told that it could be a fuel pump goin out or the timing jumped. my lil brother went to start it one day and he said something popped and startin smokin and now it wont start. if its a burnt wire i need to take the whole dash off and see what wire it is but i cant get the light knob off so i can pull the dash off. any ideas on the firing probelm and dash?


also i checked all spark plugs, and fuses all is ok there

No spark is often the ignition module (located on the distributor).

An even more common cause of no spark is a faulty crank or cam position sensor (don't know which it would be on that particular engine).

ok thanks for the added info.... another problem has risen however, i discovered im not getting any gas through my lines. theres a quarter tank in the tank but its not leavin it for some reason. ive checked all lines from both tanks and bone dry. am i correct in assuming that the fuel pump went out or could it be something else? how can i test that theory

Check for power at the fuel pump. If you have power, but the pump won't run, then the pump is most likely bad. If you don't have power, you must find out why. Check the inertia switch. Check the fuel pump relay. There is also a small ground wire coming off the battery that if disconnected for some reason, the pump will not run. FYI, when you turn the key to the run position, the pump should only run for a second or two

is the fuel pump the clicking noise? and where are an y relays switches or fuses conected to the fuel pump
