Help w/ problem sometimes no sound when ignition key is turned engine does not move Reply #6 – March 29, 2014, 06:11:37 PM this is not a very technical way of testing it but if you can turn the key on and take a long screwdriver and hotshot it if it cranks and fires change it. hell theyre only $20itll make a very audible click if it is bad, usually Quote Selected
