so i did a mini me swap on my car, everything seems to be in order, main relay is workin fuel pump workin but i dun think im gettin a spark from the last time i checked, i tried to start my car up and i hear a soft popping sound as im trien to crank it? any ideas on what this could be??

 

You dont think you are getting spark or you arent getting spark? It's easy to determine so it should be yes or no. You could have a bunch of things wrong being you did a head swap, so narrowing it down with proper information is a start.

Check your plug wires. I can't tell you how many times I have fixed dudes cars in 5 sec cause their plug wires were all jacked up. They said they didn't have any spark half the time too.

 

Umm if your battery is dead it will just click and not turn the motor over
