Crank and NO start!! :(

[Jteets75]

Okay so today i finished replacing my stand pipes and dummy plugs in hopes of fixing my hot starting issues...... So after i worked my butt off and got in done and by the looks of the old o-rings it was really promising, fired it right up drove it up the hill and came back to the same problems i was having before.....Now what do i look into doing? STC fitting and the IPR right? or is it my entire HPOP thats messed up?

Any one have an idea?

Im in the same boat, I think. Does your oil pressure guage read anything when you crank on it. Mine dosent, just wondering if thats a symptom near the HPOP area.

Jt what did I tell you before you started this job? I told you to have a new pump ipr stc turbo drain and feed lines and all dummy plugs and stand pipes with you before you start this job because usually when you get a hpo leak and fix it then it will pressure up great BUT that will cause leaks in the other bad areas of the hpo system so you need to have all replacement parts at the ready incase you need to replace them. Lol I know it sucks to drop that kind of coin on this job but you gotta do it to get it done right and not worry about it later. I had to do the same thing on mine. Only difference is I had about $1000 in parts sitting on the work bench waiting to go in. I replaced it all even if it didn't need it just so I knew it was all new and updated.

Okay so I have changed the ipr, STC, Stand pipe and dummy plugs and the truck still will not start when it gets hot, wtf is going on?

Injector seals????

[Jteets75]

That's my next idea but the previous owner had the injectors replaced 5k ago

Have you tried the shop air technique and listen for a leak?

It's his pump man his injector seals wouldn't leak bad enough to only make 250 psi. There would be a drop no doubt but for it to be the injector seals your talking they all have to be TRASHED to get that big of a leak. At least I would think so.

ON EDIT: on second thought jt you should definitely do the air check before you swap your pump. The reason I say this is that jimmy might be onto something here and here's why. You have been ripping this thing down and putting it back together did you make sure that the hpo rail nipples aren't scratched or nicked up? This can happen when removing and installing them. I would double check the rail nipples and orings first before dropping that amount of money on a new pump but I would definitely do the pressure test and double check those rails.
