2000 7.3 No Start?

[idipwr]

2000 7.3, no start. No wait to start light, guages dead. Cranks over seemingly fine. only light on dash that comes on is battery light. Radio,blower motor work etc. PCM is good tried it in another truck. Any ideas?

Any smoke? Have you checked all of the fuses? Do you have power going to the glow plug solenoid? Power at the solenoid actuator terminal when the key is turned on for the glow plugs?

No smoke, all fuses good, no power to glow plug solonoid, fuel pump not working. so something isnt getting power through.

No glow plug light means your computer is not working. Not saying the computer is bad, but it's probably not getting power. If the fuses are good, check the relays and the actual power of the batteries. (Load test.) Sounds like really dead batteries to me.

If it cranks over "seemingly fine" the batteries can't be that dead.

Mine did. Had one battery with a dead cell, the other was already weak. It cranked all day, but wouldn't fire. Needs 10.5+ volts to fire, IIRC.

Hmm, never would have thought.

Yeah, it was weird. Eventually it got worse and just the relays would click, at which point I made this video. At the time I wasn't aware of the voltage requirement, so I was going out of my mind trying to figure out why it was cranking and not starting, lol

Good batteries. Start my other truck fine. Yes, like PCM isn't getting power.
Just gotta figure out why.

Have you checked the 30 amp PCM fuse on the lower right hand side of the interior fuse panel?

Sounds like a relay issue. Starter uses it's own. You can switch them around.

Yep,Good
