I was in the McDonald's drive thru all I sudden the truck started to run rough so I decided let me get out of the drive thru and go home so I got on to the highway got up to about 50mph and then I felt the truck shut down and I used the momentum to get on to the curb.

I tried to start the truck it would crank you could see the pulleys and belt turn over but no start so I thought it need gas cause it was low walked to the gas station with a 6 gallon gas can and fill it up tried to start nothing just cranks had to get it towed home

next day tried to start it wouldn't crank over anymore it sounded like the battery and starter didn't have enough power to turn the engine over so charged up at autozone tried it again now it barley cranks and won't start.

don't know where to start?

Start by charging the battery & ordering a Haynes manual.

While that's going on, clean all the terminals on the heavy cables as these captions describe:

Jumper the DLC, turn the key to RUN, and measure fuel pressure:

Look inside the EEC:

When you have the Haynes, read the diagnostic procedure in Ch.5 (usually Sec.5 or 7, depending which edition you have); then do it.

Thank you for reply

I check for fuel by pushing in the valve on the fuel line gas shot out with high pressure

I checked for spark but I notice something weird I didn't have spark while cranking just after I finished I got a jolt of spark.

That's pointless & dangerous. Use a gauge.Follow the ignition system diagnostic procedure in Haynes Ch.5.
