2002 7.3 Completely Dead

We have an '02 F-550 w/7.3 PSD that just up and died while it was running. The mechanic here (if you can call him that!) tried to get it to fire on starting fluid, but no go (seemingly no compression). He believes that the cam or timing gears is wiped out.

The motor has something like 120,000 miles on it. I haven't heard of people having timing problems with these motors. Is this something common?

If any of the techs look in on this one, I would be interested in your diagnosis or list of common causes of these symptoms.

Thanks!

Thanks! We already talked about the CPS but as I said before they tried ether on it and it doesn't fire. A failed CPS won't prevent it from firing on starting fluid.

I agree with you. I would at least try a CPS. It's not like we don't have five or six other trucks around here to use it on if it doesn't work!
