1989.
think it was 1983
I had a Chevy blazer with the same problem. It had spark, fuel pressure, good battery & good starter. I sprayed some carburetor quick start spray & it started. They blazers have a problem with the fuel injection.
are you getting spark?
check for spark
make sure it's getting fuel and make sure it's getting spark to the plugs.
first check to see if your getting spark, or fuel
When was the fuel pump last replaced, to save time, money, aggravation, check or have fuel pressure checked. These blazers need a high fuel pressure I believe at least 59psi. You must have entire fuel pump assembly replaced on these Blazers, can get one at auto zone for around $200.00
Start with replacing the fuel filter, it may be plugged.
I would replace the ignetion module that is in the distributor.
make sure its not getting to much fuel and check the timeing/and if the wires are in the right order
my 1958 Chevy will not start sometimes
express 3500 chevy van tries to start but doesnt. when cranking stopped the engine rumbles. getting fuel can smell it.
