I have installed 2 NEW 6BY3 engines and hooked them up to the old controls from my 4BY3. The motor immediately started and ran smooth. I shut it off with the key. When I went to restart, there was nothing. Just a little solid red light for a few seconds. No gauges, no alarms, etc. The fuel pump begins pumping strong when the key is in the ON position. The battery is strong. I hooked a bypass wire to the starter solenoid and the motor spins quite fast. With the key, it won’t even try. There is 12.8v power to the computer. Pulling my hair out. Thanks so much.
