97 GMC Sierra starting problem
 

Hi, I have a 1997 GMC Sierra (5.7 L). I use the truck every day, but once every two weeks or so it won't start. I just get one click. If I wait a little while (15 sec to 15 minutes) and try to start it, it starts perfectly. After it starts, the engine runs great.
The battery is 3 years old.
The starter is 2 years old.
What could be the problem? Any help is much appreciated.

Thanks.

i would start with cleaning all your big wire connections and grounds, on my gmc the braided strap that goes from the pass side engine to the frame fell apart when i touched it. look for loose wires too

I had a similar problem with my car and I changed the plugs,ignition cables and ignition module,air filter and a radiator flush . 2 coolent sensors ,5 different relay swithes , vacuum hoses ,o2 sensor , fuel filter and still had the problem ... when I changed out the air flow sensor and PCV it was good to go ....I had gotten that tip here from this web site.. good luck

maf wouldnt cause the starter to not work

As a guy who has dealt with this on two of the same trucks yes check that braided strap the one on my wifes truck also crumbles as i grabed it Also check the connections on your starter..
