did you check for good spark and when was the last time you changed the fuel filter??

i assumed the spark was fine, and i have not changed the filter.might be aneasy and cheap place to start.

I had virtually the same issue. 95 Blazer/130K. Replaced the fuel filter (Old one looked like it could have been the original) added some injector cleaner to the gas tank drove it on the highway for a while then let it idle for a couple of hours. It seems to be starting fine now...we'll see.

I also have the same vehicle as you. I have had the same problems as you. Can you smell gas when it is running? Are you getting bad mpg? If so I think it is your fuel pressure regutator. That iswhat mine was doing. There is a how to post on how to change it.
