Question about 1999 Chevrolet Blazer
It seems like if it sits over 12 hours it doesnt want to start if you give it gas it will blow the muffler off since I have had it 5 months now I have already went through 3 mufflers
Really-- 3 mufflers,rather than figuring out why
the first one went
I guess you asked for a new muffler & no other
diagnosing, as to the cause
Now after 5months-- maybe someone on the internet
If the fuel pump check valve has failed, it will take longer
to start, but only after a long sit
You have a problematic fuel pressure regulator under the
intake manifold, that could be leaking & dumping raw gas
into the exhaust
Buy now your exhaust converters are ruined by you
procrastinating & all the raw full

sounds like a fuel management problem. the catalytic converter is getting to hot due to tryin to burn off the excess fuel not burned. causing the muffler to overheat get it scaned at autozone for free. sounds like a o2 sensor runnin lean dumpin more fuel. or a bad mass airflow sensor good luck

thats going to be in your timing...if you blew the muffler up then the timing is way off or its time for a new timing chain and gears

Sounds like you have to much gas going thru the throttle body. When you put your foot on the gas it opens the airway and lets air and no gas. The black smoke is unburned gas. Replace the throttle body and you should be good to go. It could be the fuel sensor also, telling the pump the wrong info.

Your fuel pump probably stuck. Use a wood bat or rubber hammer to tap on the tank. Have someone turn the key to on (not crank) with your ear by the tank to see if you can hear it hum for 1-3 seconds. Next replace the filter to remove any water in the lines, and don't forget to put some water remover and octane booster to "fix" the old gas that has gone stale and sucked up water.
