No start or crank

[Cheviesorrows]

Hey guys, first post and I need help!  Just swapped 5.3 w a 6.0 in my 2010 Silverado. Used the original harness and basic “plug and play”. Truck started but was in safety, then fixed that. Had full throttle control and all then truck wouldn’t even turn over. Traced it to ignition switch. Replaced that. Now I have no power to the starter. Fuse and relays are good. Any help would be greatly appreciated

Plug and play?chance of starter relay, not powered properly?

You can jump the starter at the starter , wire from big wire to small wire, - make sure truck is in park and in run.

 

If works, then trace back both wires , one to battery and the other to relay and continue tracing back

Believe it or not I got it. Both were kind of right. The truck actually started without the crank sensor installed! Crazy. The starter wire had a Knick in it and once that was fixed it fired right up. Thanks!
