engine shut down

Hello, new to the diesel forum. Was driving my 2002 excursion 7.3 yesterday and it just shut down. Will crank over but not start. the coil light comes on but will not go off. I am thinking maybe a crankshaft position sensor of fuel pump. Could someone give me a hint where i might find the sensor.

Thanks, Bob

Hi Bob, Welcome to our gang. Sounds like a cps. Its located to the left of the crank pulley, 10mm bolt as I remember. Pretty easy to change. Just clean the area before removing. Unplug the wires and gently pull out. Replace with a ford or IH part. Lube the o-ring and reinstall. A lot of us put some dielectric grease on the plug. Whats a coil lite? Is the oil full?

Coil light ?
Does the tac move when cranking ?
Do you have a wait to start light ?
Can you hear the fuel pump ?
Did it die like you turn off the key or like it ran out if fuel ??

Coil light would be the WTS light on a 2002 or newer truck...

CPS is more then likely it, however it could be an IPR...

CPS is cheap and easy.

Thanks for the quick response. I guess what i call a coil light is a wait to start light or glow plug light. It died while running. but not like running out of gas, just stoped running. No stalling or spuddering.

I'd put a Gord or IH CPS in it and go from there. If that doesn't work then you'll have a spare which you need to have anyway.
