Question edited for clarity.
Question moved the Colorado sub-category.
I wonder is you picked something up and the serpentine belt whipped the stick or whatever and disconnected the crankshaft position sensor. Can you reconnect it and start the vehicle?
All of your issues are well known and are due to battery voltage issues of a failing battery. Buy a new battery, charge it overnight. Clean the terminals and apply Vaseline Petroleum Jelly (it stops oxidization and is dielectric). Connect wires to the old battery or jump leads or the charger the battery clamps to maintain power during the swap over. Undo and lift off the clamps, clean them with a battery brush. Put Vaseline on them too. Lift the battery out of the tray and keep it close, making sure those wires don't drop off. Put the new battery in and tighten the clamps.
Possible causes
- Faulty Powertrain Control Module (PCM)
- Powertrain Control Module (PCM) harness is open or shorted
- Powertrain Control Module (PCM) cicuit poor electricl connection
- Low battery voltage
Do you have a security light flashing in the dash when you try to start it, does the starter spin the engine for but not start it up? Have you tried spraying fuel into the intake during cranking? Do you have spark? Any fault codes? All this can be the problem and other things as well, have them all eliminated as the cause.
why does the reduced power light come on , then the truck stalls. If you pull over and shut down the engine and wait a 30 secounds the truck will restart and run fine until the next time you start the truck. The truck has 48k miles
I had the same problem, and the solution was cleaning the throttle body, it does need to be completely removed to be cleaned thoroughly. I just used some brake cleaner on a rag to clean off all the carbon deposits. A friend of mine who is a dealer tech had only seen this trouble code once, and this was the solution. So far, my light has not come back on and the truck is running alot better at idle.
