1995 GMC Suburban K2500 won't start
I have a 1995 GMC Suburban K2500 with a 5.7 engine. I have a new battery.
New starter. New ignition wiring harness. All lights,radio, etc. works but wont
start. It is getting 12.4 v at the starter on the small wire when you turn the key. I
have jumped the purple and yellow wire at the transmission safety switch. Any
other ideas???
