My f150 wont start without starting fluid,
Then it idles like it has a miss, if it accelerates it missed,backfires through the intake,and dies,,I've changed the plugs,wires,and fuel pressure regulator,,it has fuel at the rail,fuel filter is ok,there's a problem in the tank switching system only one works,,you cam hear the fuel pump working when u turn the key on the engine has been changed,,it has v groove belts,,,smog pump is gone,,what's up with this truck!
you may have a second fuel pump on the inside of the frame, drivre side under the front of the drivers door,dont know what it is called, boost the fuel pressure recived from the pump in the fuel tank if it is bad it will cause a problem like you are having
guess i should have read better, sounds like a timing issue or flat cam lobe
Timing is right on the money,,,but if you turn it as far as it will go towards the throttle body it runs a little better,,,I'm not understanding why the timing is right,yet it acts like the timing is the issue
