94 blazer has issue
94 s10 blazer, 4.3L vortech. sometimes hard to start, but ALWAYS does, when you push on the gas he bogs down, let off, he idles fine. Issue started after driving a bumpy dirt raod, than got worse over time. works fine after re-start, a few bumps later issue comes back.?????????? Any ideas???????????? Thanks
Re: 94 blazer has issue
Sounds like a fuel pump with low pressure, except that part of it is fine after a res-start, until hitting bumps again- then acts up again.
Pump may be causing a loose wires or harness to act up.
I would grab and move all the harnesses under hood while running to see if you can get it to act up.
Especially battery cables and grounds.

Have a 93 Blazer with CPI, Does it have this on yours?
If so the hard starting may be the fuel lines under the plenum, replaced mine after it acting like it was flooded when starting and it cleared it up! Might check that out, these are "plastic" and mine was split under side where you had to turn the key on and see it "squirting" out to know it was bad!

Agree with you gwcchatt. Done several of those over the years. But may not explain his problem of "not always" hard to start.
