I catalytic converter was clogged so I removed it. Now the truck does not start. I will give you the code heater control circuit bank sensor. Anyone know how to fix this? I wouldn’t think that taking the catalytic converter off would prevent it from not starting. I also got an error message saying low voltage to Engine. I checked the battery and it’s fine.

Does the engine crank and not start or, the engine will not crank over? When you removed the catalytic converter was it is pieces inside? If so, it could have clogged up the muffler and it won't allow exhaust to pass through it. I would disconnect the exhaust to see if it will start. The p0050 code should not affect the running of the engine, it just means the bank 2 sensor one oxygen sensor needs to be replaced. Here is a guide to help will the no start condition and I have included how to change out the oxygen sensor in the images below.
