i have a 99 f250 7.3 and it will not start i had it pluged in and it didnt get warm at all. i was told it should start with just the glow plugs but i dont know if they are working. would that keep it from starting. i need advice im stuck in elizabethtown KY. how long should it take to change the glow plugs if they are bad. any help would be apriceated

 

does it even turn over?

 

yea it just dont fire

 

check the glow plug wires for voltage...glow plugs arent that hard to replace

 

my guess would be the glow plugs.. had them go out on a 97 7.3 here two days ago.. its -15 degrees right now so it wouldnt run and we pulled it inside the show let it sit and it fired up.. replaced plugs and its fine

 

if you HAVE to be somewhere, unplug your glow plug relay and then give it a teeny tiny wiff of starting fluid.... but replacing them would be much better if possible, i got stuck in Laramie, Wyoming and had to do that, got me home and didn't bend a push rod or anything

 

thanks for yalls input its at a ford dealer ship right now but they said they couldnt even look at it till friday and didnt know when they could work on it. right now it sucks cant go anywere except the hotel room

 

Check the relay, make sure the plug and wire for your block heater is good as well as the outlet that it plugged into.

 

i'd check the gp relay first. it's easier to replace than the glow plugs.

 

Check the Glow Plug relay with a test light. With the key in the run pos the GPR should be energized for about 1-2 minutes. If the GPR is not working then there is your issue (most common is the GPR)...

Plug it in for about 2-3 hours and it will fire right up as well...

Get it the hell out of the FORD shop before they hit you with a $400-$600 bill.
