7.3 no start

[Johnny_GIL]

2000 7.3 350 it has trouble starting in the mornings unless i plug it in any way but today it sat in the sun for likr 4 1/2 hours i went out to start it and nothing it wasnt a extra cold afternoon. i have had problems with the glow plugs before and stll have not replaced them but i guess thats the next thing but it just cranks and cranks with no fire there is fuel in the fuel bowl any help would be great

Any smoke coming out of the tailpipe when cranking and what color?

[Johnny_GIL]

not nearly as much as when i have to crank on it when its cold but some white i parked it at 3 in the afternoon and it ran fine no problems and i tried to get in it at 7 and nothing

try to measure the total current draw to the glow plugs-----------that will tell you how many are good or bad. Each one draws so much x8 = total draw

im pretty sure its not glow plugs i know i need em but in this case im saying cam sensor which i just had the recall replacement done in august. has anyone else had problems with their replacement sensor going bad?

Sometimes the new ones will go bad. I used to have a '95 that i had to plug in EVERY time it got below 50degrees outside. It was a pain in the arse. I never figured out what exactly was wrong with it....that was before the ORG though

I CALLED FORD AND THEY SAID THEY HAVE NOT HAVE ANY CAM SENSORS COME BACK BAD. HOWEVER IF IT ENDS UP BEING THE SENSOR THEY WILL REPLACE IT BUT I GOT TO GET THE TRUCK 60 MILES SO THAT THEY CAN DO THAT. ITS REALLY NOT SPITTIN ANY SMOKE OUT WOULD THAT POSSIBLY BE THE FUEL PUMP NOT PUMPING FUEL?

bottom right fuse number 30.
its a 30 amp. if thats gone it wont start. imo the most common reason this fuse goes is the fuel bowl heater elemenyt shorting out.if the fuse is bad unplug this andput in another fuse and see???

I agree with melmount. I had this problem also. The fuse would keep blowing. I just unhooked the fuel bowl heater and the fuses stopped blowing. Truck would start up fine. I don't live in extreme cold temps so i just left the fuel bowl heater unplugged. NOt worried about jelling here.

If its the glow plugs I changed my glow plugs and put the Stancor relay on and have had no problems at all. My truck used to not start even when it was 45- 50 degrees outside. she starts on the first try every time now with no block heater. It has been bout 20-30 degrees here the past week. Hope this helps
