Could be the booster. Could be the vacuum line from the engine to the booster. Worse case is the engine is worn out and doesn't create enough vacuum.

Unlikely to be a fuse, as the blower motor is working.
Check coolant flow to the heater is OK. The coolant on/off tap may not be operating correctly.
If all above checks ok, check heater core or connecting hose is not blocked.

INC means the self tests that the ODB system runs are incomplete. N/A means those systems are not tested on your vehicle. If all codes are reset/cleared, or if the battery has been disconnected, the computer will run all the diagnostic tests to establish that the systems are working properly. In most states, most of these tests must be completed with no trouble codes detected before passing inspection. You will have to run the car through a number of 'drive cycles' to get all the tests completed.

1. You should check that the fuel pump is actually running. Have someone turn the ignition on and then off a few times while you listen with the fuel cap off the tank filler tube. The pump should run for 3 seconds and then stop each time the ignition is turned on. If you cannot hear the pump then you need to check both the fuse(which you say is OK) and the relay that covers the fuel pump circuit. The relay should click when you turn the ignition on and off. If it does not you need to replace it as no power will get to the pump. 2. If that all checks out OK have a fuel pressure check carried out. Any mobile mechanic can do that for you. It is possible there is a problem with the fuel pressure regulator retarding fuel flow to the engine.

Yes

maybe a coolant thermostat that is faulty, a collapsed or perished hose.. It could also indicate cylinder head gasket/cylinder head problems. Ten miles is about the correct distance for a car engine to reach normal operating temperature. If your temperature gauge continues to rise beyond normal ..ie. overheating .. you risk causing a lot of damage to your engine. If you're not sure what to do or look for - get somebody to check it out for you

If check engine light on and code is PO420 or PO430, bad cat. converter.
