99 f 350 7.3 can fuel injector be stuck wide open I think I can here it when I turn key on pump runs to long
SOURCE: 1985 Volvo 240 no fuel no spark
well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

No it cannot. Most likely ur vehcile is EFI (Electronic Fuel Injection), which means that current must be floweing for the injectors and the fuel pump to be working. The pump allows the flow of fuel.

locate the fuse box/relay panel I believe the fords had them in the engine compartment, it soulds like your fuel pump relay is stuck in the on position just pull it out and see if the pump stops.

I realize this is an older post but I am having the same problem with my 04 F150 right now and was wondering of you had any luck diagnosing your problem? Any info would be greatly appreciated, thanks!
