Chevy blazer won't start?

Asked by Dec 08, 2015 at 09:37 AM about the 1995 Chevrolet Blazer 4 Door LS 4WD

Question type: Maintenance & Repair

95 chevy blazer, v6 vortec 4.3 4door
4Wd

Alright so we are at a loss here and
we have had all our friends who re
mechanics come out and try to fix it
and no dice.
It started day 1 with a rough idle, but
then it was fine once you got going.
Day 2 it was not only idling rough but
it was having trouble accelerating.
(Sputtering) Day 3 every time you let
off the gas it stalls and won't start
unless you spray starting fluid in it,
but then it dies immediately. I don't
want to keep doing that because I
don't want to blow the intake. We
replaced the distributor cap and the
map sensor. It has fuel and great
pressure, and it has good spark.  help
Please

Check the injector power and trigger signals from the ECM, it sounds like it is not getting fuel from the injectors if you have good fuel pressure and it runs briefly with starter fluid. HTH

fuel pump
