Hi,

Is your truck automatic or manual?

Have you tested for voltage at the starter yet?

Ask Your Own GM Question
Customer reply replied 1 year ago
automatic.....no
Truck was working just fine and all of sudden stopped working...nothing.
Customer reply replied 1 year ago
almost a new batter cable going to the starter
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

Ok. The click you are hearing- is it a quiet click or a loud clunk?

Ask Your Own GM Question
Customer reply replied 1 year ago
it is more of quiet click
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

Do you have a multi-meter to do some testing?

Ask Your Own GM Question
Customer reply replied 1 year ago
I do
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

So you will want to test to see what voltage you have at the battery, should be about 12.5 volts or so and then test for 12 volts at the battery cable running to the starter all the way down at the starter.

Next you will need a helper to test the starter solenoid.

Customer reply replied 1 year ago
if the voltage at the starter is good and the solenoid is good....what would be next? just put the starter in a couple days ago.
Customer reply replied 1 year ago
Gonna have to remove the starter to test it....will take some time.
Customer reply replied 1 year ago
am I waiting for a response?
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

To test the solenoid you will unplug the solenoid trigger wire and then have someone else turn the key to crank while you watch for 12 volts on the trigger wire.

Ask Your Own GM Question
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

If the starter has 12 volts, the solenoid has 12 volts in the crank position, then the starter has to be bad.

Customer reply replied 1 year ago
the only part that has not been replaced in the starting system is the Starter Switch, but it just looks like a plug (for lack of a better word) to me...your thoughts on that?
GM Mechanic: Jared D, ASE Certified Technician replied 1 year ago

If you don't get 12 volts at the trigger wire of the starter then you should suspect the ignition switch. We can do some testing from there if it looks like you aren't getting voltage at the trigger like you should.

I need to step out into the shop for a little bit. Let me know how the voltage testing goes.

I will not get to it until later, but you have been a real help. Thank you
