2003 Chevrolet Blazer 4.3L V6 Vortec
Repairs done prior = I went for 2 Diagnostics and nothing turned up. The battery was replaced
was first time.
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.
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.
