Parasitic draw from battery

Chevrolet Blazer 1999 Lt 200000 miles
It starts and runs from a few seconds to a minute then stalls the idler pulley is bad and makes us think it’s causing the alternator to not charge properly. It also sat for a good while before my cousin got it so I’m thinking the fuel pump isn’t putting out the right psi. It also starts to struggle when it’s in any drive gear. We’ve taken the starter off and cleaned it thoroughly, replaced alternator and battery and it ran good for a while it’s got engine noise I’m guessing could be a spun bearing because he’s ran out of coolant twice and his oil pressure drops at the same time. Could mainly use help narrowing it down.

There are several potential issues that could be causing the problems you've described with your Chevrolet Blazer. Here are a few possibilities:

Fuel pump: If the fuel pump isn't putting out the right pressure, it could cause the engine to run poorly or stall.
Idler pulley: If the idler pulley is faulty, it could cause issues with the alternator and result in a parasitic draw on the battery.
Spun bearing: If there is a problem with a bearing in the engine, it could cause noise and potentially cause the engine to run poorly or stall.
Alternator: If the alternator is not charging the battery properly, it could cause a parasitic draw on the battery and result in the vehicle stalling.
Battery: If the battery is not holding a charge, it could cause the vehicle to start and run poorly or stall.

Sudendly looses power and shuts off while driving...

Chevrolet Blazer 2000 4x4, manuel 215000 miles
For two week's prior to incident when i shut off the truck i could hear a boiling like sound coming from the coolant resivoir. Radiator was full. But i have never heard this sound before and ive been under the hood for last couple years banging on the fuse box when it wouldnt start. To the current problem... The battery light came on, then it started losing power and shut off. It wouldnt start after that and has been in an auto cocoon ever since. It had light's, and spark. But no sound when turned over. We replaced the fuel filter and my husband's friend tried replacing the fuel pump with a u… Read complete
