no glow plug light, no start, intermittant

[dieseldick199]

I have a 97 F350, have an intermittant issue, engine will suddenly quit, then not restart, no glow plug light. Truck may start after sitting, sometimes not. No lamp, no start, and the check engine light stays on longer than the normal proof illumination. Other problem is, when this is happening, scanner has no communication with pcm thru obd2 port.
No blown fuses (intermittant issue). Help its hard for my wife to jump out and push the crewcab long box when it quits......

If there's no WTS light, that means no power to the PCM or it is losing connection. You could have loose fuses, or the PCM itself is loose.

Pull your fuel filter out and visually check the heating element for some kind of looseness ,they are prone to short out .It really has all the classic symptoms .

Except for the fact the fuse hasn't blown completely.
It only has those symptoms because when that fuse goes, the PCM is also on that fuse. So once it blows, it doesn't fix itself. And anything associated with the PCM doesn't work.
Yes, it wouldn't hurt to unplug it, but I won't bet on it.

Bowl heater has been gone for at least 5 yrs. Fuse is good, its an intermittent problem, sometimes quits while driving, sometimes just wont start, sometimes its fine.

Good Morning.... I think so...
Ive got a 96 250 no mods no alrms no fuse issues presenting same problems as yours! with one exception, Ive got relay clicking every second or so in the pwr dist box under hood. this clicks in unison with check engine light and wts light when it wants to light. Frustrating electrical problems! Hope some insight comes soon
thanks

mmargush,

Have your batteries tested independently from one another (cables disconnected from both). If one battery is bad, change them both. Check all the battery cable connections (all ends!) to make sure they are clean and tight. Cheers!
