Hey Eric, love the content btw. I’m 18 and kinda new to in depth work on cars. Im trying a swap on my 1.6 1992 miata and I’m swapping the motor, ecu, and wiring harness from a 1.8 1996 miata. Motor, ecu and wiring harness are all in, and I’m having a no crank no start issue. I have a new well secured battery, new starter that works, I tested it, new ignition switch, AND the starter is getting 12 volts, AND the voltage drops when I turn the key. Do you have any idea what may be happening? I’m totally lost for ideas and would love any advice thanks Eric ☺
