Drove truck to school everything great, i leave school and it dies and try to get it going and it acts like its got water in my gas or something .it starts then it wont drive i took of fuel filter and replaced W/ new and it was black and still wont work.

Are you sure you don't have water in the fuel?

the idler is blocked in the intake, or the idle controller has failed, if you take the air pipe off the intake there is a butterfly and on the side you will see a hole, on the side you will see a device, now some time you can just spray some carb cleaner in there and give it a good flush out. also spray the butterfly and clean this up. open with the cable and do the same. you may fined that the air filter needs replacing so would do this at the same time. leave for 10 min and then start engine don't worry about it coffing etc its just the cleaner being burnt off in the engine give it a few good revs. then let it idle for 5 min, when you have done that then fit the pipes back on. run engine it should be fine now, if not repeat.

Clogged Gas Filter

Worn out & Blocked Exhaust Converter

Bad Ground at Fuel Pump

The different gas gauge readings would indicate a ground
issue with the sending unit in the fuel tank & possibly the
fuel pump shares the same ground or it is worn out.

I would check fuel pressure with a gauge & the fuel may be
there, but not enough volume

A fuel pump can last 4 years or 18 years

HELLO: It could be a frozen gas line and or stopped up filter, filter is on drivers side under the truck, looks like over sized small coke can with a connection on both ends. Thats the first place I would check.

Sounds like the true problems of an EGR. Replace or clean first and the problem should go away........Hope this helps you out.

Its fuel filter time

Keep it simple and replace the fuel filter first, if thr fiiler has not been replaced within 30,000 miles or 1 year. Then it's a good chance that it's going to be the fuel filter. 

Check the gas it could be contaminated, Not to sould like a Wise guy but are you sude it 's not deisel fuel you put in.

You really should have a code check done. There are numerous items that can give you similar symptoms. Two places to look are the fuel filter (usually overlooked till they gum up, and the throttle position sensor (but test it first with an ohmeter. You will need a manual (vehicle specific ones are available at most larger parts stores and most of those stores also do code testing free)

it is a problem w/ignition wires put a NEW not used set of wires and it should run fine even after you dry old wires the problem that you have will not go away had the same problem with 850 turbo NEW IGNITION WIRES should solve your problem
