Issues starting a 2003 Chevy Blazer 4x4 zr2 with the 4.6 Liter V6 when the engine is warm.

Asked by Michael Aug 28, 2019 at 04:21 PM about the 2003 Chevrolet Blazer LS ZR2 2-Door 4WD

Question type: Maintenance & Repair

My daughter has a 2003 Chevy Blazer 4x4 zr2 with the 4.3 Liter V6.  From
about 15 - 75 minutes after she turns it off, it'll only start with starter fluid
(very little).  After about 75 minutes it starts right back up.  We've replaced
the injector spider, distributor (shaft and cap), plugs, tested the fuel pressure,
checked the exhaust, and maybe other things.  I'm going to install a new fuel
filter this weekend {Hopefully}.  Looking for ideas.  Thanks in advance.
