Problem with my 2003 Chevy Silverado
4.8
work done to repair = changed spark plugs yesterday, no change
tech = MW
question = my truck keeps stalling when I come to a stop. Sometimes it
will stay running when I start it, maybe 30 - 60 seconds. As long as I
give it gas it stays running.
MW:
There are a few things to look for. First look in throttle body and behind
throttle blade for carbon build-up. Clean the throttle body. This is most
likely problem.
Also check for low fuel pressure.
Also have had problems with the intake manifold gaskets leaking vacuum.
Usually this will give an unstable idle and stall when hot, but not cold.
These suggestions all assuming no codes as you have stated.

Answer: The timing is probably off with all the swapping of parts,
or if you've set the timing without disconnecting the EST
connector it will be off. I would start from scratch and remove the
distributor, get the number 1 cylinder to TDC, reinstall the
distributor in the proper position, etc....then set timing the proper
way by unplugging the EST connector located on the firewall and
following the timing specs on the emission sticker. If it still burns
up parts, you're either using the wrong parts or cheap
aftermarket junk. Nothing else would burn up parts like that.

Chevrolet 6.6 Duramax Diesel
Question = I was driving my Duramax 6.6l diesel and I drove 3 hours to work it seamed fine all
day. On my way home it kinda bogged out a little and then went back to normal. I kept driving
parked and let it idle ten it died so I go to start it up it won't go the. It goes but only runs for like
a min or so. Tried pumping the primer but no fuel was coming out. And still won't start.

Answer: Could be a couple different things causing your
problem. The main thing, and unfortunately the most expensive,
is the injection pump. Those give symptoms like you describe
and once they fail, the truck won't start anymore. It could also
be something simple like bad fuel, or even a clogged fuel filter.
Those are simple enough to check, so I'd do that first. Less
likely is a fuel pump that went bad, but that should be checked
too for power and ground and see if it's building pressure
before the injector pump. Probably going to be quite expensive
to repair, as when diesel's go out, they go out big.
