I turned my 99 K1500 sub off in traffic yesterday and it wouldn't
restart. The dash lights would come on when you turned the key but
when I turned the key the starter wouldn't turn as if the tranny was
in drive. I reinserted all the relays and checked all the fuses
related to the car starting and something worked. Any ideas what the
culprit could be? I don't want to get stranded somewhere with the
kids but I don't want to pay someone $65 an hour to go on a fishing
expedition under my hood either. I imagine this is one of those
things that has to be broken at the time to find what is broken.
Yesterday I was at the first tunnel on I-40 East in the mountains of
North Carolina. I got lucky that it started because is in the middle
Just yesterday I had a similar problem. 99 Yukon.
For me it ended up being crud buildup on the pos battery cable. It was
similar to your situation my wife drove it to church and when we went to
leave it wouldn't turn over at all. Anyway try tapping on the pos battery
cable and wiggling the cables a bit you may see whitish crud drop out of
them. I'll bet that is what you are dealing with. I ended up getting a
little tube of grease they sell for batteries and after cleaning the cable
ends with baking soda and water and rincing them well I gooked them up with
the grease. I assume it is just dielectric grease but it didn't say the
tube was $1.00 . Anyway check the voltage meter on the dash while the
engine is running I would bet it is around 12 volts. While you are running
it should be right up at 14 though. If you clean the cable it will jump
back up there.
But did you put it in yourself? Did you clean the cable ends? It is a
double cable connection and crud can build up between the two making just
badenough of a connection to cause you not to get enough cranking amps to
turn the starter. It can also cause the battery to not get quite enough
charge from the alternator.
I used to have an '88 Silverado that when the engine was hot the starter
wouldn't crank at all. I kept a pop bottle of water with me and when I
accidentally shut it off at the wrong time I would squirt the water in there
to cool off the starter. It looks like the starter in these is different
than that one though so I don't know if they would still do that. ( I don't
recall if that was before or after I replaced it.) How long did you sit
before you were able to restart the engine. What you could do to test this
theory is drive for 1/2 hour or so and then shut the engine off and
immediately try to start it. If it doesn't start let it sit or squirt the
starter and then try again without doing anything else. Though your
description of the problem was exactly what I delt with, if you leave
everything the way it is I am certain you will have trouble again.
has had. The original Delco went bad. Its' warranty replacement went
bad which prompted me to buy the AutoZone battery. Now it went bad
after 2.5 years. All replacements were made after a test determined
the battery was the culprit. I have usually gotten 4-5 years out of a
battery. This is 4 batteries in under 5 years so I wonder if there is
a gremlin hiding in there that the diagnostics can't find. This
battery I just replaced really got drained at the first of the year.
We went on a week long flight out of town and came back to the airport
to find that a map light had been on for the whole week. I had
forgotten that you can open the door with a key but had to that day.
That might have done permanent damage to it to go so low for so long.
But that doesn't explain the other 3.
Try checking the alternator for "OVERCHARGING"
It causes the electrolyte to boil and the plates to sulfate, rendering the
Anything more than 15 volts at a no load: ie. no lights on or radio or
heater/A/C fan on means you are cooking the batteries to death.
That would have been what I checked for after the second battery, because
the law of averages that you can get a bad battery. Can not possibly be as
bad for you as my dad's and mine were!
I will chime in late here. I have an '00 Silverado that did the same
thing. When you try to restart, do you still have dash lights? Mine
would fade off when the key was in the start position like they didn't
have enough power to stay on even though the battery was brand new. I
installed the new battery myself, scrubbed all the cables, used
dielectric grease on all the fittings and still had the problem. I
then cut the rubber protective piece off the positive cable and it was
heavily corroded. I got a new side mount post from Autozone ($6 IIRC)
and cut off the corroded part of the cable. I put the new terminal on
the end of the cable and it has been good for 8 months now. Hope that
