Ok on the way home 1/2 mile from my driveway i pull up to a stop sign,and my 94 f250 4x4 super cab with 228xxx miles on a non turbo 7.3 5 speed died like i run out of fuel quickly swapped tanks but no help,i put new injector pump,injector,glow plugs and glow plug relay in it back in the summer,truck has run great til today.gauges both show 1/4 tank so maybe empty so i put 10 gal in rear tank,bleed the lines at the filter air valve and had my brother pull me down the road but would not start,didnt hit a lick.then i noticed my wait to start light didn't come on nor did the glow plugs click,i checked all my fuses they looked good,i checked the fuel valve again had alot of air bubbles in the fuel.im thinking no getting fire to the ip pump,or something else electrical,any help i would greatly appreciate it.

 

Fuel pump died.

 

maybe seems to be getting fuel,what could be causes the glow plug wait light not to come on,i swapped the glow plug relay out for a new one off my parts truck,didnt help but if i take a screwdriver across the wires it makes the glow plugs click and the wait light comes on.any suggestion ill give it a try

OK i dint alot of research and figured out if i hot wire the fuel shutoff siloniod my truck fires right up but the wait to start light still does come on.so im guessing i have a bad wire.i check every fuel i could find on this truck not one is blow,does any know which fuse goes to the fuel shutoff,and the glow plug relay,i could use a diagram,thanks

well found the fuse diagram,check the fuses again probably 3rd time found a a big 20amp blown replaced it and fired right up,the same fuse goes to the glow plugs as the shutoff soleniod,so im probably gonna carry a few spare fuses now,glad it was an easy fix.only took me 5 hours .but it fired right up every thing worked great.

 

i would look over your engine harness. make sure there are no chaffed or rubbed threw spots on it.

 

ok thanks will do.
