doing a sohc swap romeoville

yo fellas iam doing a sohc swap the car does not fire up or crank what the hell plus the firing is done right and and the tdc is correct and the 15degrees on the crank so no clicking so i dont know what wrong i need help plus i have new fuses and new gas so if any one can help me i would aprecaiate it

start by looking at the starter circuit. no clicking or attempt to crank usually means that the starter isn't getting power.

i got a diff upper wiring harness and a lower wiring harness and i am going to hook up everything up together and ill make sure the starter circuit is good too thanks
