The jump start may have blown you alternator or voltage regulator. If so, you have an inactive charging system. You must have a good battery for this to work, Disconnect the positive cable to the battery. Use a battery charger to slow charge your battery. When the battery is fully charged, reattach the positive cable and try to start your engine. If it starts take the truck to a shop or auto zone to have the charging system checked. Fix what is needed.
Any time a vehicle is jump started, do so with the hot battery car not running and its ignition off. If it is running and your car starts one or both charging systems are usually damaged. There may not be damage if it is GM to GM or Ford to Ford, etc., but to be safe, do not let both cars run at the same time when connected.
double posted, why? JUMPS OK AFTER JUMP WORKS AND DRIVING, AND STOP AND KEY OFF IT WILL NOT CRANK. did i guess right? that means , check all fuses first. even the alt fuse (large) 1-battery bad? #1 top failure all cars. 2-Charge system bad. (is the charge/ batt warn lamp glowing when running car, bingo.????
3-or phantom drains. (if no crank just after stall then it not this) if drains while sleeping yes.
the tests are easy, a dirt cheap voltmeter 13.3v to 15v running is good charge system. if 12v and falling not.
if the battery is bad, the charge system can shut down, so, the best practice is to try a know good battery out of 2nd car, do you have battery to barrow, this is TOP CHOICE< not thinner wallet.
if the good battery fails then the charge system is failing (note I said system and not a part) or the belt missing or slipping to the alternator.
btw the 4.3L PCM runs the alternator PCM is engine brain. btww, same true 2.2l engine. the regulator is in the PCM.
so is the charge/bat lamp in cluster on key on, lamp test the jump start it , it runs does the charge./batt.lamp go out. id be all over that lamp, costs nothing to look.
Take battery to Autozone and they will test for free,may have a dead cell,or go to WALMART,better prices and they will test your battery also for free,just got me one from there,last one was from there,last 6 years and 3 months and they are warranted for 5 years.Mine was real weak,10.5,should be 12.6.
probably not sounds like either a dead or weak battery or bad connections on the battery posts. first take battery cables loose clean terminals and hook back up hopefully then it will start. or use jumper cables and see if it will jump start. if it jump starts then you no its not starter.if it doesnt jump stsrt then clean posts and cable ends and try again. hope this helps. best of luck
I'd start with a battery first. Sounds like the battery has 1 or more dead cells in it. the battery may have all the volts you could want but if it doesn't have the proper amperage it won't crank the motor. You can have the battery load tested for free at Auto Zone or Advance Auto. A simple down and dirty test would be to disconnect the Positive cable and jump the vehicle by connecting directly to that and a good ground on the block. The motor should turn over as long as the vehicle you use as a jump has the proper amperage in it's battery. If the vehicle starts then it is the battery, if it doesn't then you need to look at the starter and other components.
If the vehicle turns over and don't start first check fuel , you said good battery now the electrics but before you start checking do you know how to check or how the engine works , if no get someone to plug in a car code reader
It sounds like you have some **** in the gas tank that is being drawn to the pickup blocking it.
Have seen this and because it seems so random, it can drive ya nuts.
You might carry a coffee can with you and pull the line from the fuel rail when this happens stick it in the can and just have someone turn the key on for a few seconds.
Beware though, it comes out with force.
Also possible is a failed fuel pressure regulator.
Those aren't expensive and . . . well, not very good either.
