When this occurs is the issue it will crank but not start or it will not even crank?

With the key on, what is the theft light doing?

When this occurs what do you do to get it to start?

Hello again Chris here,

  1. I have to assume you were not pleased with my help, because you have not replied or rated the post.
  2. What would you like to do regarding your question now?
  3. Do you still need help? Please reply I want you to get equal to or more than what you paid for.
  4. This post is coming up on the 7 day mark where it times out. That can prevent me from being able to post answers to your replies.

Thanks Chris

Chris , I have been on the road lately and haven't had time or place to respond and apply the answer to the truck. Key turned to start and nothing happens, dash lights and instruments go to "0".

Do you own a volt meter?

What is the battery voltage?

Customer reply replied 1 year ago
I do have a voltmeter. Battery is full charge. Seems the anti theft light( lock on instrument panel) stays on all the time.
Customer reply replied 1 year ago
Starter was checked by auto shop and it is ok.
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago

Remove the start relay, is there one pin there with battery voltage and then another with the same with the key held in the start position?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
that is going to take awhile to accomplish . I will have to find the starter relay.
or are you speaking of the solenoid drive on top of the starter?
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago

It is in the fuse box under the hood.

Replaced starter relay , truck continues to have issue of not starting. Doesn't even turn over and no noise from the solenoid . There is a noise/ click sounds like it is coming from mid front of engine. when key is turned to on , but not to start.
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago

I will wait for your reply on the tests I mentioned to do at the starter relay pins.

Customer reply replied 1 year ago
Went to parts store got a new relay , replaced the old one and still have the same issue. The keys are cut keys and do not have the chip or memory in them. I have not used a button start hooked up to the solenoid , but at this point I am not sure if I want to do that.
