hello all need some advice. i have a 96 blazer 4x4 auto 4.3CSEFI and what i thought was a manual happened to have only 1/8th of the electricial diagrams. i guess the question is can i still get O.E.M. sevice/repair manuals. still got no spark here and power to the coil on the red or orange wire but no arc across to frame tried changing coil and also did the primary/secondary ohms test all good. so i kinda think the security (your valet) is locking out the spark. I dunno
