Got in the truck to go to work this morning and since it was raining I had the wipers on intermittent and headlights and radio on. 99 f250 with 120k . It kept stalling out instantaneously. Sometimes it would just hiccup and sometimes die out completely. I replaced the cps with the new gray one about a year ago and I do have a spare but this is unlike that. I did find a reference to a similar story in the archives. Dtc codes are p1249, p0500, and p07a00. From what little I can store in my tiny brain the first two are normal on a programmed truck but I can't find a reference to the p07a00. Any ideas about any of this. Thanks in advance. Jsw22250

 

do you have a programmer?looks like the one I got with hypertec

 

You said it was raining and you have a 99 there has been a leak in the windshield that most can't see and it will leak onto the back of the fuse panel check to see if it is wet on yours.

 

I do have a hypertec programmer. But no leak in the windshield that I know of. Where does this occur. jsw22250

 

Whereabouts does this leak generally show up at. The fusebox being wet or at the dash level?

 

Most have found the gem and the fuse box wet and did not see a leak so the leak was not noticeable.
Edit: the Gem sits on the fuse panel.

 

Cool. OUt to the truck I go. jsw22250

 

When you lose the hypertec you will lose the goofy code
