The most common probelm with the 1999 chevy blazer, as well as the s10 pick up and astro van of this year is the fuel spider. After doing alot of research on this with my husband and father in law, we found that Chevy actually decided it was a bad design and completely redesigned the spider the following year. Change this to an after market spider, a remanufactured one is the way to go, because new the run about $600 just for the part. Also, my mechanic said this is the cause of this, as I had the same problem, exept that when it warmed up in the afternoon the engine would act like it wasn't getting fuel and buck on me.

Could be a bad coil wire... usually low fuel pressure, maybe a plugged fuel filter. either of these are common on these vehicles

1999 blazer only starts when primed and then wont start after sitting


Black smoke is usually extra fuel, but you say you are priming it to start so that could be why.
Have you checked fuel pump pressure before and after cranking ?

How to check for a bad fuel pump in a "99" blazer, 4.3 motor? I sprayed starting fluid in air fillter and it would fire but not run.


If gas and starting fluid does not create a spark I believe the coils or ignition module is your problem
To check the fuel pump turn the key to the on position without trying to start the engine. Once turned to to on position the fuel pump will run for 5 secounds to prime fuel pressure to the injectors. If heard running you have a problem above as mentioned

Silverado not starting unless prime


There is a check valve in the fuel pump that sounds like it may have gone bad. Check the fuel pressure at the shredder valve, there should be 60 to 65psi during the prime and will drop 5 psi when the engine is running. Once the fuel line is primed, check to see how fast you lose your prime. Since you replaced your injection system, we can eliminate the fuel pressure regulator leaking which was common on the injection system your truck run's on. If the fuel pressure drops fast then it's going to be a bad check valve at the fuel pump and it may be time to replace the fuel pump it self. Good luck and hope this helps. Note: do not try to start the engine with putting gas through the throttle body, it's been know for small fires to start and burn the spider injectors.

Engine wont start without priming with gas first, then runs well


i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

1999 Chevy Blazer 4WD wont start


Sounds like the bendix is stuck in the starter. When this happens, the starter energizes and turns, but the gear does not kick out to make contact with the flywheel. Have someone tap on the starter while cranking the engine.
