Check the fuel pressure with a gauge, let the truck sit off with the gauge on it after running watch for the fuel pressure dropping off if this is the case your check valve in the pump is bad and requires a new pump, -jeff please rate

If it has sit for a long while, I might put a couple drops of oil in each cylinder, turn the crank by hand. You could jump the starter relay to get the starter motor to crank a little. If you try something like that, make sure tranny is in park or neutral and functional parking brake is set.
Your security system has the pellet in the key? You could try a relearn procedure?
Turn the ignition switch to start, then release to the on position
The security lamp should be on
After 10 minutes the lamp will turn off
Repeat the 10 minute sequence 2 more times, with 5 seconds between them
Turn ignition switch off. Hopefully on the next start attempt it will start?
Sometimes after a vehicle sits for a long time, little gremlins get to chewing on the wires, cause all kinds of problems. Any applicable trouble codes?
Check for spark to the sparkplug. Try a shot of starting fluid as having gas pumping and having the fuel injectors opening are 2 different things. If you have spark, then the fuel injectors may not be working. Quick diagnosis is to use starting fluid and see if engine tries to run. This indicates problem is not lack of spark but lack of fuel getting into cylinders.
Clean any terminals to shiny clean as the green gunk will cause a high resistance to current flow, Remove the spark plugs and put a quantity of diesel in the pots ( say 50mls). Allow to sit for about 1/2 hour and this will allow any rust on the cylinder walls to soften and helps initially lubricate the bores and rings. Crank it over for a few times and refit the plugs.. This allows the oil pump to pick up oil before there is load placed on the bearings... Replace any fuel filters. Have you replaced the water pump . If not why waste you time trying to start it until you do .
Let the car sit undisturbed for 10 - 15 minutes, then try to start it. Check the owners manual if you have it. Sometimes, on various cars letting them sit awhile will allow the system to reset itself. On others sometimes rapidly turning the key from off to on, without turning to start 3 to 8 times within 10 seconds and then on the last turn to the on position leave it there until the horn chirps, at that point turn the key directly to start, or turn off first and turn to start. If all this fails, a GM dealer can reset the system.
Starting at the front of the engine, this is cylinder 1. The coil sits
on cylinder 6 and the other cylinder it pairs with is cylinder 1. The
next coil sits on cylinder 2 and it pairs with cylinder 5. The final
coil sits on cylinder 4 and it pairs with cylinder 3.
if it is posible for you to drain the the old gasoline out and refill the tank with fresh gasoline that would be great, but if you only have a1/4 tank and draining the tank is not posible fill your tank up with supreme gas not regular the better grade gas with the high octane will dilute the old gas and help burn off the gas when the car starts.if you have more then 1/2 a tank try to pump out the gas with a driil pump, you can buy these a your local hardware store insert hose in filler neck of the tank.you should also remove the spark plugs and with and oil can add 8 good pumps of the can of motor oil in the cylinders do not replace plugs **** with a freshly charged battery turn the engine over few time in 2 or 3 second intervals this will kleen any rust that would have built up on the cylinder walls and also lube up the cylinder wall so that at start up the cylinder wont be dry ,add a few more sqirts of oil between turnovers.Replace spark plug if old ones look bad put spark plug in and start her up its going to smoke a bit at firts **** it will stop after the oil that was put in the cylinders burns off,let the engine idle for 10-15 minutes before putting any strain on motor give it a chance to clean out cylinders burn a few tanks of gas and change gas filter it should be fine.
start by making sure it will crank ,check battery,remove all old fuel,pull the plugs and put marvel mystery oil in the cylinders,before you put plugs back in spin the motor over with plugs out and blow the oil out of the cylinders,yes it will make a mess, then put good fuel in and give it a shot
