2002 7.3L Won't stay running!

I have a 2002 F205 7.3L Diesel. The other day i was driving normally down the road when i quit. Just like i shut the key off. It wouldn't start. Let it sit about 1 hour and tried it and it started up. (no codes showing) I thought it was the ICP sensor so i changed it. still the same problem. Then i tried spraying water on the motor to cool it then it would start right up, but die when it warmed up. I narrowed the spot to the HPOP. I can pour just a little water down there and it will start right back up. Could it be the IPR or a bad HPOP, or ICP sensor? Thanks, Daniel

looks like you got one of them, hydro 7.3's.

i think its coincidental. Your symptom is similar to a CPS sensor going bad. You already should have a spare in the glovebox, anyhow. Start there and proceed. With no codes, it cant be something major.

Sounds like it could be a CPS (Cam Position Sensor). Mine did that a couple years back I changed it and haven't had a problem since. Make sure you get one from ford I changed mine with one from Napa and it lasted maybe six months. They are not to pricey and easy to change. Front of the engine you'll see it by the crank pulley has one bolt holding it in I believe it takes a 10mm socket, swap it and you should be back on the road.

I tried one from Oreilly AP too, and it ran worse than before. I had already ordered some on Ebay ' - parts_master''s Emporium - eBay Motors' they showed up the next day, and since I installed the black colored CPS, no problems.

With those CPS, you have to run a OEM ford one or your truck will run twice as bad as before. They aren't nearly as expensive as they once use to be. Like less than $20 so make the trip to a ford dealer and get one, buy a spare one to keep in glove box

You think it's the IPR?

Thanks, Daniel
