So I drove the truck on saturday, woke up sunday and it wont start, all it does is make ONE CLICK. thought it was the starter so I hit it a few times, no avail.
I check the relay and crank fuse, its good. Battery is a month old. Change the starter and still nothing.
Just one big click. I had a kill switch on the starter, remove it and still nothing.
What could it be. "Computer"?. All the diagnostics checks seem fine when your switch it on, fuel pump etc.

Please help,
Thanks

 

Check your connections battery and stater. Have battery tested might have a draw in the car and it drained the battery.

 

Checked those. Battery is fine, starter is new.

 

If you are just hearing a click it sounds like a bad connection.
