Still stalls

[maxbry]

I just had my cam positioning sensor replaced again, due to the recall. Since that time my truck has stalled twice??? Extreamly fustrating to say the least, not to mention dangerous.. A thing to note, I could turn the key to the off position, and could restart it. This last time, I noticed that the glow plug light indicater on the dash would not come on. And until it does, the truck won't start. Also, confusing, is that when the light does not come on, and while trying to start the truck, the tach will not move, indicating a sensor?? Help, Help, Help... Fustrated in Fernley

What year is your truck?

I'm sorry, its a 2000 hd 350 turbo diesel 7.3

no tach movement and no wait to start light usually indicates that the #22 fuse is dead. that fuse supplies power to your computer, therefore you won't be able to restart your truck.

Fuse 22 on the obs trucks is for the fuel heater Im not sure what it is on the superduty. Usually the superduty's don't have an issue with the fuel heater element shorting out, but it certainly is worth a look. Check all the fuses and relays in the power distribution in the engine compartment. The computer or pcm controls the wait to start light so if its not on you have issues with the pcm.

i agree , it may be shorting and just not blown completly yet, just unplug it

Where is the fuel heater elliment located? Sounds like it could be the culprit. Once the truck sits for awhile, I can restart it, but only if the glow plug light stays lit. Weird I know, Until that light stays on, I will turn the key complety to the off position, and to start, and the light will not even come on? This same as the fuel heater element? Is it actually heating the fuel, or the plugs? Thanks guys for all your help thus far.

What or where do I look for the pcm? And can this be tested?

It is under the fuel filter. when you take your filter out look in the bottom of the filter housing
