G.M. start problem

[GlockCop]

Ok. I know we have some very talented mechanics (professional and shadetree) on here. My question. A couple of days ago the Suburban (1999 K1500 5.7L motor) wouldnt start. A loud click but wont turn over. I take the starter off and take it to Auto Zone and have it tested. It tests good...three times. Drive gear kicks out and not pulling too many amps. So I bring it back home reinstall,and it starts...twice. Then the same loud click. I tried to loosen the starter a little...same result. Any ideas? Ive never run into this before and the only thing I can find online is the motor is frozen. That isnt it. Any ideas or suggestions are highly appreciated.

Dead battery? Not enough amps to crank the starter with a load on it.

Have you tested the battery and connections?

connections try jumping a wire from the battery directly to the starter (yes I know how big of a PITA this is)

other than that have you checked your battery or tried a different one? I've seen batteries cause a lot of funny issues and start a truck fine but not a car.

Test the battery and connections. Also check the security light. Is it flashing fast of slow? PM me and I will give you some ideas.

First: I AM NOT A MECHANIC, I just fix my own vehicles when I can, before I pay a mechanic.
It sounds like, the Battery Ground wire, or the ground wire on the Cylinoid(sp) is loose, or corroded where it can't get a good ground.

Well guys it isnt the battery. It lights everything up good on the dash and the headlights work fine. I jumped it just in case and it made no difference. Connections seem tight and fairly clean. Keep the ideas coming. Its got to be simple I would think.

Everything can work fine but the battery still won't start a vehicle. Have battery tested.

It's the battery damnit! Seriously, have you had the battery tested, it can be so low on amps that it won't jump start.

OK guys ... this is BB ... GC is off to get the battery tested ... I certainly hope that is all it is ... this little adventure is gonna cost me cuz the Suburban is "mine" ... lol
