I had a water leak from my water pump I replaced the pump only unplugging the hoses that went to it to do so . Now my car won’t crank well it will very rarely but not for long. I was getting a crankshaft sensor code replaced it and still won’t crank. I’m not sure where to go with this next. Vehicle listed above is an XL 1500 Denali 6.0 vortec.

So I found out my ECU got a little bit of water in it, now it’s throwing up throttle sensor codes.

Could these random codes be a result of a failing ECU?
