No,not without a lot of switching of electronics

1993 is OBD1 & 1996 on is OBD2 System

The engine may be okey-- but not the induction
system or any electrical

try the ignition module.

ignition switch or starter relay or a wiring problem

look under the hood in the big fuse panel and look for High beam headlight relay the relay is more than likely bad

I dont know if they had it in 96 but there is something called a speed control deactivation switch. Maybe check your owners manual about that.
