When I turn on my heat, the pump attached to the boiler comes on but the pipes don't get hot and the radiators never do either.
I've bled them and believe they are hot water radiators (since there is a pump), so from what I understand sludge shouldn't be an issue.

We ended up bleeding the radiators, upping the pressure, and replacing the thermocouple.
After all of that, we discovered that
flames had been shooting out of the front of the boiler and melted half of the valve, messing up the electronics for the pilot light.We ended up replacing the entire boiler since it was 35 years old anyway, but the reason for the issue was the messed up valve.
