1994 blazer


Asked by Aug 29, 2017 at 09:12 AM about the 1994 Chevrolet Blazer 2-Door 4WD

Question type: Maintenance & Repair

I have a 1994 Blazer here is the situation
with it it wanted to run really rough and then
it just quit running. It's sat for a while and
when I try to start it again I'm not sure
exactly what happened but something
sparked and it literally blew the muffler off
the bottom of it and it will not start ever
since then. What in the world could cause
the muffler to blow off like that I know
catalytic converters get clogged up and stuff
but I've never heard of anything like that
anybody got anything on this one

the fuel charge didn't burn in the cylinder , it made it to the exhaust and exploded , being a cold start opens more possibilitys , timing , ignition upgrade may be in order


it has a new ignition and the timing is good as far as i can tell. its on mark with the light. i will double check though. appreciate it
