I've got a1995 4x4 Chevy blazer it's a v6 4.3 vortex
with throttle body it will turn over all-day long
without a problem but it will not start it's getting
fuel fire and air it's got new spark plugs and wires
whole new fuel system and new air filter no leaks
any were I'm not sure what else to look at its not
the pic up pack it was just changed two days ago
it's got a new battery I've had it tasted several
times to make sure can anyone recommend
anything else I could check that I might have
looked over I've checked everything that I now to
check that has to do with it starting and mabey this
Will help it was running like a top and all of the
sudden while sitting in my driveway it started idling
real rough and died after about two minutes of it
doing that and if you tried to give it some fuel it
would do like its not getting enough fuel and would
almost die out but wouldn't but once it died I
thought it was out of gas so I put some more and it
started right up and was fine until the next day
when I went to leave in it it started right up with no
problem I went to take off and it would barely go
and done the same thing as the day before but this
time it would not start after it died
