Hello all,

Every once in awhile, my 2008 Suburban refuses to start. I turn the key and nothing happens.

To get it to start, I have to get a battery jump. Then it starts right up.

I had the battery and alternator tested at two Autozones and battery and alternator tested good.

I don't know if I have a short somewhere or what to do.

Thanks all for any help or recommendations.

 

Check both battery connections on both ends.

 

Thank you 73shark,

I will check battery connections on battery and wherever the other ends goes. Will this stop the car from starting sometimes?

 

Any other recommendations please?

 

What shark said.....bad ground may cause problems. If the battery is an AC Delco....replace it immediately. Its a POS.

 

Check your battery connections, maybe hit the metal contacts with a wire brush. Make sure the grounding strap is tight on the block and firewall.

But if that's your original battery, I say replace it.

 

Even if the battery tests OK, can you tried another?

May be worth a shot.
