If I shut it off will not start until it cools down

a/c only blows out defrost vents--need estimate on repair cost

only on when truck is idling or I stop accelerating

The original issue, H20 was dumped into fuel tanks, I drained, filled and cleaned out both fuel tanks. Also replaced both fuel filters. Truck became extremely hard to start and had a bad miss/chug while idle and driving, seemed to run better the warmer the engine got. I replaced the IPC sensor and the FICM module, had the FICM reprogrammed. After that it would start up with the first cycle of the glow plugs and ran a lot better but still had a slight miss while driving. That's when I pulled up to a stop sign and it died cranks no start. could it be the fuel injection pump? These are the DTC's that were set before I replaced the ICP and the FICM, PO269, PO611. These are the current DTC's now, PO098, PO113, PO403, PO405, and a P2290. Any info on what you think this could be would be greatly appreciated.

Just changed EGR valve hoping this would help. Tailpipe smokes a little bit bluish from time to time when traveling slower or when engine is not up to full operating temperature. Please help. Thanks.

Also hard to start im guessing fuel pump is going out

i changed the float assembly that didn't seem to help unless i have the wrong one. tank could have 5 gals in it and read 1/2 full its 38 gal tank any help would be nice thank you larry

battery went dead and reset the computer to safe mode. I am experiencing low/rough idle, engine light on. How do I remedy this?

The check engine light came on when I accelerated rapidly to pass someone. Then a few hours later I accelerated rapidly again and the light began to flash for a few seconds. I drove the truck one more time and the light is still on, but it has not flashed again. Did the flashing indicate a misfire? What should I do?

5lb boost 0.0 on front I don't know how this could be

before changing the glow plugs the truck was very hard to start but would stay running. I notice an oil residue on the old glow plugs, is that normal. Truck will not stay running after 3 seconds.

This normally happens in cold weather. Any recommendations or solutions?

only at high rpms

i have traced it to #2 fuse and then to the blue plug on insterment cluster but every thing works fine gauges ect. ? bad cluster??
