No start/ hard start / IAT reading -40f , coolant temp reading -74f , boost reading 38psi.. sounds like running on 2 cylinders

So the car was running fine today, I went to change the valve cover gasket and decided to add PCV system back to stock.

Did BLT , Cleaned injectors ( with eBay battery powered device ) and put in new injector seals.

Did BLT and holding pressure

Go to restart and just get a bunch of cranking.

Tried bump starting down 6 blocks the car would turn on but if I hit the gas it would die immediately.

Only way I got back home was to remove the intake to PCV line and let that breathe ( I started removing all new stuff or anything Changed once it wouldn’t start

Check logs and getting -40f IAT, -74coolant temp / 38psi Boost

Well that’s not right.

I’ve gone over the car physically and can’t see anything I did wrong or forgot.

I’m thinking it’s either my ecu frying/ some type of short circuit / or other electrical issue.

The fact that my logs are reading these screwed numbers LOCKED at idle means something correct?

Getting a CEL for coolant temp sensor circuit malfunction - this couldn’t cause this correct?

Is the car on speed density? Did you unplug the speed density harness? Did you bump the thermostat housing ? All those seem like sensors are unplugged.

Indeed I bumped the thermostat housing and made wires touch each other causing sensor ground.
