I recently installed new heads on my ranger,now truck wont start, or turn over,

it doesnt do anything, no niose no click, nothing..

Ok Now check for ground wires( back of heads and area tht connect to where you were doing the head job) and poor connections at the battery! With a little YOU TUBE help, you can probably see a video on how to bypass the solenoid and MANUALLY engage the starter. Make sure your neutral safety switch is operating too and the vehicle is in park.
