7.3 just died!

I was driving my truck down a gravel road when it just dies and now it wont restart. When I crank it, no oil pressure shows up either. I seriously don't know what to do, I need the truck pretty fast this weekend for a hay haul. I was told could be the oil pump or the oil pressure sensor (Not sure if this is right?), but I'm not sure.

My usual No Start -


WTS Light? - do you get it when you first roll-on the key? (shows the computer is running)

Do you see cranking rpm on the Tach? Do you have a spare CPS to try?

Is there fuel in the fuel bowl now? Does it refill after cranking? (open the drain level to check)

Can you hear/feel the pump running (below the dr seat, against the framerail)

Could the fuel gauge be giving a bad reading? (Below 1/4 tank?)

Is it cranking fast enough? - it won't even TRY to start if cranking too slowly.

Is your truck "chipped"? If so, remove it as a Test.

Yes

Yes

Yes

Yes

Could the fuel gauge be giving a bad reading? (Below 1/4 tank?)

Gas gauge doesn't work

It's cranking pretty fast. Faster than my tractors.

Is your truck "chipped"? If so, remove it as a Test.

To remove it, do I need to disconnect the batteries?

Yes disconnect the batteries, check the oil level in your hpop.

Going to sound really dumb asking this. How do you check the HPOP oil level?

I'm replacing the PCM to see if that is what it is. I got a new one Friday, but when I opened up the box, the New PCM was broke

Check the Fuse going to the PCM under the dash, the fuel bowl heater is on the same circuit...

Unplug the fuel bowl heater (back of the fuel bowl, almost at the bottom) replace the fuse and try it...

This has happened several times to our fleet of 7.3's, my personal vehicle included.

I will try that on Monday once I'm off my 24 hour shift. Thanks for the info everyone. I'm also getting a new PCM on Monday as well, so I'll do that and the PCM at the same time.

But Wait,,,, you have a WTS!

What that's telling you is that your PCM is Up & Running (that's why I ask)

Did you remove the tuning?
