My 2004 ford expedition cranks but won start, I disconected the fuel line at the fuel filter and there is not fuel pumping when I crank the engine. I checked fuse, realay and inertia cutoff switch and they looked ok . Can somebody help

Check fuel filter for clog. is the fuel pump activating? If so. check for clogged filter. Check fuel pressure for proper pressure. I am assuming you have spark??/

fuel pump. check injector rail fuel line valve for pressure.

Check for fuel at engine and for spark at coil

These details will help,keep updated for more help.

it might be the fuel pump take the output hose off of it and crank the engine and see if fuel comes out of the pump if it does the fuel pump is not the probelem. if it doesnt come out or if it slowly comes out than you need a new fuel pump

First check the fuel cut off switch. Located pass side kick panel ! There will be a red button push it down! Second try another own key ! Need to no how many miles? Pos fuel pump

If it a diesel then you must be aware that when changing a filter and pump they must be full of fuel, otherwise it won't **** the fuel into the engine.

Fuel pressure test , is there spark ? Videos on youtube showing how to check .

Hello You will have to reset your fuel pump switch located passenger side right foot kick panel when you press it it should stay down if this does not work your probably looking at a fuel pump not working.

sounds like an electrical feed problem to the fuel pump ??? anything could be wrong ,try checking for a feed with a meter ,
