Question

Won't start.

I have a 2003 Chevy Silverado 2500 HD. 140,000 miles, 6 liter engine. I have all electrical systems as normal, but it will not start. When I turn the key to start, I get nothing, no click, anything. My battery is @ 2 years old and I use the truck almost every day for hauling and trailering.

Turning the key

What about when you turn it to the accessory position? Do lights, gauges, etc., work? If not, do you have access to a DVM to check the battery voltage? If "yes" the same applies. The easiest thing to check is the condition of the battery. It's not that unusual for something to be left on that drains the battery overnight.

Turning the key

Yes, when in acc. position, I have all lights etc.

Since you have lights, the next thing I'd look for

is to see if they dim when you turn the key fully to the start position. If they dim, the start switch is probably OK. If not, you're getting no current to the starter solenoid. The click one normally hears is the thrust of the solenoid that engages the flywheel and the high current relay for the starter itself. That relay is usually integrated into the starter assembly. and is just a set of contacts. Your starter uses more current than any other device in the car so the lights should dim if current is there but but the starter does not engage or turn. If the lights don't dim, the current is either not there or inadequate to start the car and either the battery itself or something in the cabling to the starter isn't allowing current to flow properly. The easy thing to check is the terminals and ground connections. There's a connection to the starter that's also important so you have a lot of things to look at in order to track this down. Good luck.

Okay, got the tester out. Battery is going bad. Jumped and started right up. Thanks for all the info and help!
