Could be water in the gas?

 

most definitely not water in the gas

 

fuel gauge see if it bleeds down after shut off motor bad fuel pres reg

 

Sure sounds like the ignition switch to me too. Connect a test light from battery negative to the pink wire at the ignition coil. Light should come on, and remain on, with the ignition in the RUN and START positions, no blinking allowed when you go from RUN to START. This will tell if the ignition switch is supplying voltage to the coil. The results will tell which way to go next.

 

If this truck has over a 130000 miles on it there is a good chance the the fuel injectors are worn out. This is a very common problem change them and you will be happy again.

 

i got an update. truck is having a real hard time starting now. but when boosted starts fine. brand new battery. still same outcome. gonna change the starter out after Xmas maybe starter is taking too much juice?? the 14v oming off an other vehicle seems to be my safe ticket

 

to me sounds like you may want to check the fuel regulator it may be on it's way out,
when this starts to happen you get the same hard start issues

 

Are you running with cold weather oil?

 

yep 5w30

cranks good just not firing.. and sometimes back fires when trying to fire on start up

how can i post a video?

would show you guys exactly whats oing on

 

Distributor cap & rotor? They can cause symptoms like this, (especially aftermarket ones), and not necessarily set a DTC if it acts up during cranking. Pull the coil wire out of the cap, prop up the terminal ~1 cm away from ground and crank it over. Should be a blue, not orange, rythmic spark. If that checks OK, try using AC Delco parts.
