When I'm driving down the road and I go to pass another car I have no Acceleration and whenever I'm just driving regularly and I get to about 30 or 45 miles an hour my check engine light comes on but no codes are sent I'm not towing I'm not pulling its just everyday driving. also when I start the truck when she is cold she fires right up but after I have ran her for a while and then shut the truck off and then try to start her back up she doesn't want to start up and it takes several tries or I have to use starting fluid to start her back up.

Sounds like an IPR or HPOP issue. If you are not getting acceleration, then you might not be getting enough high pressure oil to fire injectors properly. Mentioning that you have hard hot starts points in the same direction since the oil is thinner it does not build pressure as easily. Injectors need at least 500 icp to start/idle. Are you able to monitor ICP and Duty Cycle with a CTS2 or TorquePro or something similar?

My truck is currently in the shop because the HPO system blew a massive leak and oil was everywhere on top of engine. Check to make sure you don't have any obvious leaks near the HPOP/reservoir, IPR, HPO lines/fittings.

Using starting fluid is bad ju-ju. If you feel that you must you need to disable the glow plugs or you WILL have a permanent no start!

OEM sensors? If not you need to get you some of them. Check the tinnerman nut on the back of the IPR too.

I did have a HPO line blow on me and I was able to replace it and I replaced the o ring on the plug on the back of the HPOP....since then no leaks.....oil level has maintained since then....how would I check the tinnerman nut on the IPR?

His location is noted as Glendive, MT. Although if you are on a mobile device you may not see it, even then it may not be accurate.

If the CEL comes on, a code is set. It's just that our trucks are not truly OBD-II compliant and whatever code reader you're using (even the ones at the auto parts stores) don't work. There's a great app for your Android phone called Torque (free) or Torque Pro ($5?), but you'll need an OBD-II adapter. There are cheap ones that some folks have had good luck with, but the recommended is OBDLink MX Bluetooth. If you have a bluetooth enabled Windows laptop, there's also Forscan (free) which offers a lot of diagnostic and troubleshooting tools - essentially everything a dealer could do for you -that will use the same OBD-II adapter.
Either of these will let you see what's really happening when your truck stalls, why it's not starting when you're cranking it hot, etc. If you're going to own, drive, and do your own maintenance on one of these trucks, this is truly the first tool you need to get in your toolbox. And while Forscan is F-L-M / some Mazda / some Jag and some Volvo only, Torque will also work with just about every OBD-II car/truck out there, so it's very helpful.
And welcome to FTE, I'm certain you'll get the answers you need soon enough!
