Okay I need help advice and pics if available. My car in short won't start. Key in and no sound. to cut a few problems out
1.battery is new and I get full electrical power to the car
2.alternator is new
3.wires are checked and not loose
4.its not the security light engine lock out. Tried that too
To the issue. My car won't start no click sound that the starter is trying to go off. But I have good reason to believe its still fine but I'm not ruling it out. I drove the car earlier in the dar and it started 0 struggle. Key in and engine was running the same second. Now no attempt. But I also JUST had the trans fully rebuild overhauled and since out of the shop I've only driven it 4 times
What's anyones opinion on this. Please help

 

**UPDATE**
My starter is fine, i checked it and jumped my car using the screwdriver trick to short the solonoid bolts on the outside but heres a video i took of it changing gears

 

Honestly easiest way to find out is take it to a mechanic who has the tech 2 scanner and access to the gm database (or a chevy dealer but they charge a buttload). It sounds like the bcm. Have you made sure all the bcm fuses and relays have been checked? It can be so many things bcm ECM PCM or passlock someone with a tech 2 scanner will tell you in minutes what's wrong.
