Removed transmission to change rear main, now no start.

[95xj05gtp]

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?

Are you sure you have the shifter reinstalled correctly? It sounds like it might be the park sensor switch. If it thinks your not in park, it won't start. Just an idea.

Ever try putting it in Neutral and seeing if it will start? I agree with the idea of the park sense.

Was there a solution to this no crank problem? Just replaced a transmission and neural safety switch and pigtails. No crank no start when I was finished. 2001 gmc jimmy
