I've been working on my car for 4 weeks now and still cant figure it out. i changed the oil pump and put it back together and it wont start. I broke this fan cooling switch that plugs into the block, and i broke a bolt on the starter siliniod. I turn the key and not even the interior lights come on. There is no sound. My light came on fine when i turn them on. I'm 95 % sure i hoocked up the starter correctly. It was fine before i took it apart. Could it be Wiring problems? or something else, i tested the starter it's fine.

 

Yes, the solenoid bolt you broke has become a break in the circuit. Needs to be correctly fixed.
