Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
Just one click sounds like a fuse is blown or the starter relay is bad.
Let me get the wiring diagram. Which engine came in this?
What model is it?
Check the "IGN A" fuse in the underhood fuse block, left side of engine compartment for being blown. If not, try either swapping the starter relay or install a new one and try again.
