Pleas help! No start when hot
 

Truck starts fine when it's cold but as soon as it's up to temp shut it off and it won't start back up. Hit it with ether and it starts, also it run's 100% once started. I just got the codes P0344, P1212, P0605. I'm stumped and I really need my truck back up and running. I have limited use of my right hand right now so I don't wanna do more than needed if possible, I'd like a direction to look in. Thanks :argh: also truck is a 95 with a zf5

Also I changed fuel filter and then found the ipr bolt was barely finger tight so I tightened that back up

See how that does after you tightened it. But your IPR could need cleaned or rebuilt

Same issue after tightened, might have to try rebuilding it

Changed the icp and cps still same issues. Being that it runs fine I don't think its fuel but what's left, ipr?

How long has it been sense an oil change. I have seen oil start to break down and cause this.:humm:

Only like 1500 miles

Do you run any additives in the oil?

Pull the IPR, clean it and reinstall
