Solid security light, fans on high, crank no start
I was driving home one day, my car scraped and broke the crank position sensor connector I replaced it and the crank position sensor. But now the car will just crank and not start. Have a solid security light on and the fans turn on full blast. I can’t hear the fuel pump kick on I tested all the relays and fuses but still nothing… Any ideas on what else it could be?

When the connector broke, the wires probably touched and fried the ECM. The ECM is very fragile, sending 5 full volts for more than a couple of seconds could have fried a solder joint in the ECM. Fans on full blast is how I know the ECM is done. When the fan control module loses contact with the ECM, it defaults to full blast to prevent overheating.
