Keeps blowing fuse

I have a 97 F250 diesel with the 7.3 engine. about 120,00 miles, runs grait. just recently i replaced the fuel tank selector, both battery's, and the starter. it started just fine and ran normal. i drove it about 80 miles with no problems. it sat for about 2 weeks and now every time i turn the key it blows the fuel pump/glow plug fuse.

Disconnect your glow plug relay and try it, the relay may be shorted out

    witch wires on the relay did you disconnect... there should be 2 heavy wires with 13m nuts and two small wires with 8 or 10mm nuts... try disconnection all four and see what happens. if this is what you did before and it still blew the fuse then try pulling out the fuel pump relay (if it has one i can't remember if the diesels do) and see if the fuse blows then. If the truck dose not have a relay for the fule pump then unplug the pump. The fuel pump should have a plug that is aprox 15 to 20 inches away from it on the frame rail... let me ask you, dose the fuse blow as soon as you turn the key on or dose it blow when you try to crank the engine.

    well the fuse must protect another circuit, if your owners manual only lists the glow plug relay and the fuel pumps then you will need a wiring diagram to determine what additional functions are supported by that fuse... other than that i have no other suggestions... sorry

i have that same issue and mine is a 97. I think its either injection related or the high pressure oil pump my buddy's just went out and its doing the same thing our trucks are doing. the best bet is to get rid of your truck or pay 2600 bucks unless your a skilled mechanic or know someone who can do it for cheap because the parts only like 20- 100 bucks

I have f-250 diesel. keeps blowing fuse #22,glow plug controller. what might be the problem

You should start with the glow plug relay/timer.Check it to see if may be shorted.Remove the smaller wires going to it and turn the key back on,if the fuse does'nt blow then replace it,if it does then you need to unplug the fuel preheater in the filter housing and try the key on thing again,pretty sure it's one or the other.

try loosening the injector lines a little then crank probably has air in the lines and wont blow through the injectors,once fuel comes out while cranking,tighten them,if this is the problem it should start but run rough untill the lines are tight,it shouldnt hurt much to get a little fuel on the engine

1992 f250 with 7.3l diesel that shuts off in curve

well you can extend the pick-up tube by fabricating a hose with perfaration to lay flat on tank so its always submerrg'd. Shouldnt be to bad to do...just reqiures droping tanks....Other than that try your best to keep 1/4 tank minimum....but obviously the pick up tube on the bottom of the fuel pumps sending unit is up to high., and when you take the turn the pump, pumps like normal but gets air/fuel mixture and causes the stall due to enriched o2 levels...No way around it either...

Good luck hope this fix's'ya!

no it wont but a cloged fuel filter will increase the pressure from tank to filter and overload the amperage in fuel pump and posibly burnt fuse also check for bad engine mounts if engine moves while is under load it might contact some wires and burnt fuse
