Sprocket454ss
Newbie
I have a 1991 350ss, it was a 454ss with the 700r4, it still has the tbi automatic wiring harness still in it, but now it has a nv3500, I no longer have spark and i have changed everything, coil, cap and roter, and even plug wires. When you click the key to on the left turn signal automatically comes on without touching anything, so this made me think it was a ground problem, I have added three grounds going from the engine to the body and the engine going inside the cab. I was hoping that this would've fixed it but it still has the same problem, I knew it had to be something inside the cab, so I unplugged the fog lights same thing happened, no spark.I plugged the fog lights back in then I pulled the gauge cluster, this is where it gets confusing, with the gauge cluster out of the truck, it has spark, turns on, lights don't start turning on by themselves everything just works, but the second you plug the gauge cluster in, it kills it, and I lose spark. if any of you have ANY idea what is going on please, PLEASE tell me, I will try ANYTHING yes I have tried multiple gauge clusters
