2002 Silverado 200k I pulled the trans to replace the rear main seal and put the truck back together and now I get no response when I turn the key to start. For troubleshooting I have: Replaced the NSS, both of the NSS pigtails No start, dash is indicating gear, reverse lights activate. Pulled starter and had it tested it multiple times and its good If I connect a test lead to the solenoid it turns over but dies after a second. If I apply 12v to the purple/white wire and the orange wire in the NSS harness the starter relay clicks. If I connect those two wires together and jump the solenoid the truck starts and stays running.] 12v is good from battery to starter, ground is clear. NO 12v at the 12v solenoid wire at key turn. Assuming this is my issue is it a common thing for the ignition switch to go bad and cause this? Could i have broken the wire while working under the truck? Am I missing anything that I should be testing?
