Question about 1999 Chevrolet Blazer
Posted by Anonymous on
The first... easiest & cheapest assumption is your
IGNITION KEY has become damaged and is
Simply having another key to try should
tell if that is TRUE/FALSE...
After that the BEST THING TO DO is to make sure
all your battery connections are fresh & clean.
For most of the sane world...
this is not a big deal... but AS for me...
I think static SPARKs and losing battery... is
a HUGE problem ( you should always know all the CONSEQUENCES OF REMOVING POWER in
ADVANCE of so doing ).
You need to consider your BATTERY (both sides).
((Body, frames & engine ground distribution ALSO)).
What I am about to propose can be seriously damaging
if done improperly... (extreme caution)
IF I am understanding you correctly...
"all dash lights radio 4WD selector
switch leds are extinguished"
The most likely source of your issues is your
PRIMARY (large cable) POWER & GROUND...
This THEORY can be disproved... when the
CONDITION is FAILURE MODE...
Make sure the vehicle is fully secured & NOT in gear...
(as all your SAFETY switches are being BY-PASSED)...
When the CONDITION recurs...
Apply BATTERY directly to the "S" (start)
terminal of your starter SOLENOID your starter
should engage (good enough).
That single test says your primary battery & ground
systems are OKAY... leaving you to consider the LOGIC
portion of your vehicles starting system & OBD systems.

I had the same exact thing happen to me, I have a 97 blazer and after hours of screwing around with it and several different options... it turned out to simply be the ignition switch.

Testimonial: "Cheers really appreciated that the second opinion was very helpful, mine also just turned out to be just the ignition switch. SO what will be next ???"
Try replacing the fuel filter first, but it sounds like your loosing your fuel pressure prim when the fuel pump is not working. The fuel pressure should be 62-65 PSI with the engine not running the the ignition key turned on and should drop about 5 psi when the engine is running. If you turn the engine off and check the fuel pressure, it stat steady for morn then 15min. If it drops fast, then you have a leak at your fuel pressure regulator (common) or your return fuel check valve which is located at your fuel sending unit.
Start with the simple and replace the fuel filter, it could just be to dirty to pressurize the fuel system fast enough giving you the hard start.
Thank you for using Fixya and good luck
