Dies and won't start when warm SolvedSolved

Chevrolet Blazer 1993 k5 212000 miles
My 93 k5 blazer 5.7 will start and run fine when the engine is cold. After it warms up it dies. Try to start it again and it sounds like it tries to start then the starter will bog and sometimes it turns over fine but just won't start until it cools down.

Power loss

Chevrolet Blazer 1995  198 miles
Hi everyone, I have a van blazer 95 vortek 4.3 v6 ls and it was having an oil leakage through the crankcase gasket. When taking it to the mechanic, not only the crankcase gasket but also the filter and oil were changed. After that, the vehicle started feeling weaker than before and even once stalled on a parking ramp. A buzzing sound could be heard as if the gearbox was out of oil. What might be happening? In case it has something to do, I share that before the tuning of the car, only the change from first to second gear could be felt as the car jerked a bit. Luckily now this problem is not there any more. Has this ever happened to you? What might have been?

I tell you buddy that, when removing the carter and filter, you can check whether there is a transmission damage, either because the oil contains waste or little metal pieces or because the filter faulty. You should have started by scanning the vehicle.

Thank you Becca for your comment. I was thinking that may be the mechanic touched something else than only the crankcase gasket because I noticed him in a different car location than the one this car part is installed. It might be that he damaged the gearbox a bit in order to charge me even more.

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.

Squealing BEFORE turning ignition.

Chevrolet Blazer 1987 K5 350 EFI 75000 miles
I have a 1987 K5 Blazer that is making a cycling squealing sound when you click the key to the "ON" position before engaging the starter. Not a belt issue. Truck is not even started, and will not start. Starter turns and tries to crank, but will not. Squealing sounds like it near passenger side firewall, but cannot pinpoint

The problem with your 1987 Chevrolet Blazer is likely related to the starter solenoid. The solenoid is responsible for engaging the starter when you turn the key, so if it's not functioning properly, the starter won't engage and the engine won't start. The squealing noise you hear before turning the ignition is likely a sign that the solenoid is not engaging as it should.
There are a few possible reasons why the solenoid may not be functioning properly:

Worn contacts: The contacts in the solenoid may be worn, which can cause them to stick or not make a proper connection. This can result in the solenoid not engaging properly and the starter not functioning.
Loose connections: The connections to the solenoid may be loose, which can prevent the solenoid from functioning properly. Check all connections to the solenoid to ensure they are tight and clean.
Bad solenoid: The solenoid itself may be faulty, in which case it would need to be replaced.
