I was going to get my 1991 pontiac firebird washed and all of a sudden it just died on me when I was driving...tried restarting it, but it wouldn't even turn over. Dash lights come on...but no click of the starter or solenoid. We've replaced the starter and solenoid...we've also replaced the ignition switch..and we've also replaced the coil, checked the fuse links, then we took the ignition module to the auto parts store and it was working fine. The nuetral saftey switch is working fine too..plz help...we don't know where to look next.
