Exclamation 2002 7.3 Dies

Hello all I would greatly appreciate any help w/ this problem. I have an 02 7.3 that just dies while driving (doesn't matter what speed) it did this to me about a month ago while I was out of town & I had a shop look at it & they replaced the CPS. About 2 hours after picking the truck up it would not restart so I called them they came to the truck & put their scanner on it & found that the high pressure oil pump was only making about 150 psi. So I told him I would tow it to his shop, but fortunatly it restarted & I drove it down there & they replaced the pump. Everything was good for almost a month to the day & it started to have the same symptoms so I took it to a local shop & it has the same codes as before. I replaced the CPS again to no repair. The new shop put a computer in it because the scanner said there was a board problem, again no fix. Now we are all at a loss, because it just continues to die & eventually resart. The high pressure pump does produce low pressure when it doesn't start but one time it did produce 1,100 psi & didn't start. Any ideas?

Thank you,

Justin

Justin, to the site. Someone will be along shortly to help you with this. It might be possible you got in a bad batch of CPS. I am no tech and this is just a very slight possibility. Good luck though

OK well I doubt that is it unless the same truck stopped at the two stores. Someone else should be along shortly though.

Yup, most people don't relize that the ECM has more computing power than most home PC's lol. Hence the reason the list of codes goes into the thousands lol
