It all started with a busted HPOP line a couple of weeks ago. Towed it home and removed the line. Ran to Ford and got a new line and fittings. Little did I know i could have just pulled the line from the fitttings and snap a new line in. Could have saved me the tow of truck, goose neck trailer with 12 large square hay bales home. Too make a long story short I pulled the HPOP to get my big hands in there to hook up the line but before that I sent it to Clay at RiffRaff for an upgrade and thread hole fix. Installed the HPOP, replaced the ICP and EBP sensor over the weekend. No problems after install until Monday morning. Idiot light came on the way to work and 30 miles later it shut off going down the road. Started right back up, drove another mile and shut off for good. Towed home, tried to pull codes with Actron but it showed no codes with idiot light on. Grabed the Hypertech tuner I bought back in 2000 for the truck and it shows a code of P7A00. I have searched on here for that code with no luck. Oh Yea the truck started right back up once back home. I changed out the CMP sensor and no luck. Any ideas?

My truck is a 99 F-250 SD with 7.3 all stock and one owner.

 

I've never seen that code either...

So is the truck running or not? Sounds like it's intermittent maybe? what is the CMP sensor? Do you mean the CPS (Camshaft positioning sensor)?

 

Yea I meant CPS. It is running but worried about driving it too far. I'm not sure if heat has anything to do with it. When I drove it Monday it ran fine down the interstate but after I got off to head into town and driving at 35 mph is when it acted up.

 

That code is not an OBD-2 code for our trucks...

Could be an injector issue, I had a similar issue years ago, truck would start and run fine when cold. Once warm the injector would leak enough oil to kill the truck. It would not restart until cold again.

 

I'll look into it. Truck has 310,000 miles and all stock. Any way to check to see which one could be leaking?

 

Ya, get the valve covers off and start the truck... You will see oil coming out of the oil spouts, that's by design. What CSIPSD is saying, you will see oil coming out from around the base of the injector where it goes into the injector cup...

 

Thanks
