2005 sierra starting problem

[hwalte]

hi my 2005 sierra has a starting problem, sometimes when I turn the key I get nothing but a click, try a few times nothing, then all of sudden it starts no problem. I have lots of battery, lights etc working fine.

 

I am thinking its the starter after all while the truck only has 110,000 KM on it is 10 years old. when it does start it doesn't make any kind of grinding or hitting noise, sounds normal

 

I hate to buy a new starter just to find out that wasn't it but not knowing if it will start when I shut it off is stressing to say the least.

 

thoughts, advise, options?

I would first check battery cables for clean connections. Load test battery to be sure its fully charged. Then check for power to the small wire on starter when in the start position. If you have power and it does not crank, starter bad.

Could be just loose or dirty connections at the starter as well

There should be an auto reply to every new topic on electrical issues that simply says to remove every connection between battery and the end of battery cables, inspect for cuts, corrosion under the insulation at terminal ends, clean and also clean the terminals on the battery no matter how clean they look.

 

Step two is to test battery, charging, and starter for correct operation. Do not skip the first step, regardless how clean you think they are.

99% of the time it is a starter the brushes or soliniod puck dont make contact at times so it will just click
