I try to start my vehicle '95 Chevy Blazer, I turn key, all lights on dash come on, but I don't hear the CLICKING sound that it should be making when you turn the key to start. The connecting sound comes from the direction of the glove box. I've taken it to a dealer and they don't get any code from the computer..I have been told that there is no relay switch for my Chevy blazer. What could this be? Also, I disconnect the battery for approximately 15 minutes and reconnect and certain times it will start. Right now it hasn't started in over a week. PLEASE help, I am going crazy and running out of money with all of this process of elimination! Thanks for any information you can give me! Hecc56

I would check your fuses.

 

First of all, your Blazer has several relays. Their location depends on the body style, at least from '96 on. I have a 2-door, and there are 3 relays behind a plastic cover in the glove box. On my friend's '99 4-door, the relays are in a box under the hood.
I just went through a detailed diagnosis of the fuel system wiring on my '96, so I may be able to offer a thought or two.
You mentioned not hearing a sound you expect to come from the glove box, so this suggests you have a 2-door. Is this correct?

 

I'm assuming your fuel pump relay is bad but as for where It's located I have no idea I've never worked on a 2nd gen blazer.
