turn key on all lights come on when turn key to crank position nothing happens radio light dims dash lights don't. Checked batteries fuses and relays.

 

Neutral saftey switch

 

check the connections on the starter and make sure they aren't corroded

 

check to see if you are getting power to the starter solenoid while in the crank position if you are most likely you need a starter. You could try this next trick and see if it works or not and not a real good practice I know but while holding the key in the crank position smack the starter motor with a hammer sometimes the brushes get stuck and smacking the side of the starter helps free them up (sometimes this works and sometimes it dont)

 

im having the same problem it starteded then went to crank it up agine and nothing so i replaced the starter, batters, and all i get is the click of the relay im lost and just cant figure out why it wont start HELP PLEASE!!!!

 

Check voltage drop across all power cables and the starter.

 

you replaced the starter? and the batteries?
