2003 Chevrolet Blazer 4.3L V6 Vortec
Repairs done prior = I went for 2 Diagnostics and
nothing turned up. The battery was replaced was
Question = For a year and a half, I been having a
problem that the starter will not start. No notice at
all. Not even your normal clicks in the starter.
Then after a few seconds it will start. This April it
made me wait 10 minutes. After that is when I had
it first checked out. Found nothing but replaced
battery. It worked fine for 3 months after that 10
minute wait. Then it acted up again. However the
frequency was not like it was when it was acting up
a April. Then at the end of August, it made wait 10
minutes again. An hour or 2 before that I drove
threw heavy rain for a couple of miles. That was
the last time that happened. I had the garage
checked out, nothing turned up. What could this
be? Electronics or starter? Oh, yeah, the security
light is not on.
Answer: The key is to do some diagnosis when it is
acting up. You would need to check for power at
the PURPLE wire on the starter when key is in
CRANK and not starting. If there is power, but
wont crank, then you need a starter. If there is no
power, then possible neutral safety switch problem,
or a loss of 12volts to the neutral switch. A cause
could be a faulty ignition switch or wiring problem.
The ignition switch feeds power to many different
circuits of the vehicle.This is all assuming you do
not have a non-factory alarm or remote start,
because these cause all kinds of problems.

Repairs for this problem = Replace fuel pump approximately 1 -
1 1/2 months ago, since the gas gauge says full when engine
turned off and empty when engine turned on
Question = Now when the engine is turned off gas flows like
fountain from under the hood.
The gas leak you have is most likely the fuel feed line to the
engine. Look on the back of the drivers side of the engine. This
is where the lines go into the injector assembly. Either a line has
sprung a leak, or a seal on the lines going into the top of the
injector assembly is leaking. Remove air duct from top of engine
throttle body to see this area better.
