Please help!!!! Truck in limp mode, wrench light

Husband has a 2003 7.3 Ford F-250, he pulls a trailer with a skidsteer most of the time. He has had issue with it overheating pulling up hill but he just refills with water if need be. Two days ago, headed home with the skidsteer on the back he lost all power and truck just died. Had a man pull just the truck to a close abandoned gas station. After thinking it was the alternator and going to grab a new battery we got back and it started and ran fine on the way home. Following morning he got in it and made it maybe 10 miles before shutting down again. Had both batteries tested (both are 3 months old) and one showed up bad, (replaced under warranty) changed it out and drove fine. This morning, he was headed to work, battery light was flashing on and off, then all lights then the wrench. He pulled over turned off and back on and let it sit and is trying to limp it home. It keeps throwing the wrench light and seems to be misfiring.. yesterday when he put the new battery on and started a bunch of black smoke came out.

PLEASE HELP, we know nothing about fords. He just got this work truck about a month ago. Has over 300,000 and is a diesel.

It could be a LOT of things on a truck with 300k mi. with an unknown history. You'll soon be swamped with suggestions from the experts here. I would start with reading the trouble codes but be aware that most auto store code readers don't work on these trucks.

Post your location. Maybe there's somebody close by who can help.

When you said "lost all power" ...do you mean all electrical power?
Sounds like alternator could be bad since y'all are having so much electrical trouble with new batteries but there may be something else going on as well.
There are a lot of folks here that are pretty smart, someone else will chime in with better suggestions.
I know how frustrating it is to be stuck on the side of the road.

We are in northeast Alabama.. heís not had this truck very long. His boss may know more about whatís been done to it. I know he just had a oil change a few weeks ago. And has check all fluids yesterday.

He said all his gauges, lights, radio everything went. Then he said the truck runs maybe 30 second after then acts like itís starving for fuel. Heís able to switch it off for 10-15mins and it cuts on and makes it about 3 miles or so before doing it again.

Definitely sounds electrical. Something which is easy do to and doesn't require a lot of specialized knowledge is to just start checking connections. Check the battery connections, grounds, etc. Check all the wiring harnesses for broken connections and rubbed and/or exposed wires. There's a big 42 pin connector on the driver's side (photo here) which can break and sag and allow the big harness to rub on the valve cover and cause all sorts of electrical gremlins.

Grab your multimeter once you get the truck started wait until glow plugs relay (GPR) shuts off, THEN check the voltage you’re getting at the back of the alternator. Report back. You should be seeing high 13’s to 14.4ish. Once you have this number then check the batteries with the truck running and see if that voltage is making it to the batteries. Report back …

I will tell him to do that! He said when it starts there is smoke/steam coming from left side of the motor (not the actual motor) he said thereís a plug that has some oil around it? Not to sure what exact part heís referring too

Pull the connector off the ICP and see if the electrical connection is full of oil, if it is you need a new OEM ICP, NO AFTERMARKET SENSORS.

If power is lost then it will cause it to starve for fuel, since the fuel pump is electric, like you said it was doing.
It sounds electrical to me, I don't know what the symptoms are when the computer starts to go out. Keep checking back, someone will come along that has experienced something like this before.

Leslie, if not familiar with these trucks tracking electrical problems can be daunting task. If you have a local shop that deals with just batteries - shocks - tires etc I would take it there and have them load test the batteries and check out the alternator / connections. Some national branded shops will do it for free hoping you will purchase their products. If not even the small charge is worth the diagnostic. They will have the equipment necessary to guide you in the right direction.

From your description I would of suspected low oil in the crankcase, but that would not cause lost of electrical power as you described.

This symptom also point to low oil in the crankcase, but not the total electrical failure. You did indicate the oil change. These trucks need ~ 15 quarts of oil and proper type.to run. Any information on what type of oil and quantity when doing the oil change? Might have two seperate issues.

CPS failure will cause strange shutdown also, but not the electrical issues of everything turning off. CPS would cause symptoms of the engine just shutting
down with everything else acting normal (except the TAC not responding when cranking)

Good point, might be multiple issues here. Thanks for pointing that out that possibility.
