7.3 diesel stalls for no reason.... Changed fuel filter. Any ideas?
Does it have a alarm system? Ecm fault idle down relay?
what year?? does it die at high temp??
I'm having the same problem on my 2001 Excursion. It doesn't get hot, just either idles for a while and dies, or just dies going down the road. It doesn't give any warning at all, just suddenly shuts off. Any thoughts?
Does a eng warning light come on? And the alarm system may be playing up
No ENG light. I'm not getting any warnings or codes.
If it has a diesel pump that means 1 : your idle position is not properly adjusted 2: your diesel cutout solinite is not working properly 3 : the plunger r getting worn out !
Look for fuel leak cause I have same problem n found fuel was leaking from injector pipe so change it n the problem was solve
I fixed this same issue on my 2003 diesel excursion 7.3 liter and guess what it's a recall free fix. The Cps module is defective. Cam shaft position sensor is faulty and simply shuts the truck off.
Have a 2002 7.3 excursion and the consensus seems to be the CPS sensor....cam positioning sensor. It was the subject of a 2008 recall. Location of the offending sensor is at the 10:oclock position at the front of the crank shaft....its attached to the timing mark arm. only 1 10mm bolt holds it in. If the sensor in your truck is black in color then its the old one and its possible to have it replaced for free at the dealership for free per the recall. The new sensors are a light grey in color and are around 30 bucks at the dealership.......do not buy an aftermarket part from a chinese auto parts store....don't ask me how I know. PS....most 7.3 owners carry an extra CPS in the glovebox.....30 bucks is cheaper than a tow truck.
