I agree. I wouldn't have changed anything till I put my comp on your rig. It will tell you if theres low fuel pressure, low voltage or computer .I agree. I wouldn't have changed anything till I put my comp on your rig. It will tell you if theres low fuel pressure, low voltage or computer .

I CAN tell you that its probably not your coils packs. Possibly yoyur computer if you haven't gotten it fixed yet. But if you have I would like to know what it might have been.

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??/
See if the CHECK ENGINE light comes on and have the codes diagnosed. Else, might be a fuel supply thing (clogged fuel lines, clogged fuel filter or bad fuel pump, etc...)
Probably the inertia switch for the fuel pump..You owners manual should show you where its located..See if the button has pop up ..If it has push it back down until it clicks..If it wont stay down then hold it down and see if it will start..If it does you will have to replace it..If thats all good then check the relay for the 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.
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.
No not the fuel pump. You most likely need to do a tune uo. New spark plugs, wires, fuel filter, air filter. Deffinently change out the spark plugs. I would suggest using autocraft, autolite (fords brand} or some densos or ngk for better performance. Hope this solves your problem.
This system should be self priming, however if it did run out of fuel, I highly recommendchanging the filters.After doing so have an assistant turn key to run as you listen for fuel lift pump running,(under drivers side floor attached to frame, one of the fuel filters is part of pump,the other filter is on top of engine) Could have hurt pump by running dry. They are notorious for hard start after filter change and/or out of fuel.Hope this helps.
I agree. I wouldn't have changed anything till I put my comp on your rig. It will tell you if theres low fuel pressure, low voltage or computer .
