Check the battery cables. Make sure you have voltage at the starter. If not, then test the cables. If you do have voltage then start checking the ignition switch.

 

I should have stated the head lights come on all electric works radio ie ,,, were is the starter cyl. on starter or fender well,,,,

 

The starter will be on the block of the engine. Right where the transmission bolts on.

 

Yea we pulled the starter and had it tested ,,[ shot ] new one 152.00 ,,, time to check out rock auto,,,,, Robert

 

They have good prices.
