On 2000 Toyota Tundra eng light is on,replaced BK2 OXY sensor 1.code P0155 .Where in the fuse box is the fuse for this sensor?

Both banks use the same fuse, so it is not the fuse, or you would also get a code for bank 1. Code 155 can come and go. If you are not experiencing any symptoms, give it a couple days to see if it stays on. If it does, inspect the connector carefully as well as the wiring. Make sure the harness is not touching any hot parts of the engine. If all that looks good, Use an ohmmeter to check the heater inside the sensor. The not sure which pins are the heater, but there should be two pins that have a few ohms resistance across. If not, the sensor is bad.

Elecrical faults 307 glow plugs and heater switch have no power

Peugeot has got a BSI unit and are known to sometimes cause problems. It is normally situated inside the passenger compartment under the dashboard. However, it is not a unit which can be serviced. If a fuse is blown or not making contact, one can be lucky to get it working again. I suspect a bad earth connection. Google "Peugeot Service Box". It is a service offered to Peugeot and Citroen owners, where the necessary info may be obtained.

Glow plug light comes on then engine cuts out

i have had this before but i cannot remember what i done to cure it ,its a common fault on VWs as well ,its not the heater plug relay box thats at fault but something else and i honestly cannot remember what i done to cure it ,the light comes on because its lack of fuel if i remember correctly ,common rail injection system and something happens that shuts it down and i have done this fault but i cannot remember ,i seem to recall a problem with the fuses and a bad connection or high resistance across a fuse where the connection pins not the fuse were making poor contact but iam not entirely sure as old age means i have old timers desease big time

did you check for fuel pressure at the fuel rail?
listen for the fuel pump when you turn the key on
did you change the wire harness when you changed the pump?

Hot air blowing with climate control off.

you may have an air mix motor problem or a mode control motor problem. there is a test you can do that may help: 1. turn the ignition switch on. 2. turn the fan switch off. 3. press the recirc control button to select recirc (recirc indicator light comes on.) 4. press and hold the recirc button to select fresh (recirc indicator goes off). Continue to hold the the button down until the recirc indicator comes on for two seconds and then goes off. If the system is okay, the recirc indicator will stay off. If there is a problem, the recirc indicator blinks a code to indicate a fault. 1 blink=air mix control motor/circuit fault. 2 blinks= mode control motor/circuit fault. 3 blinks= evaporator temp sensor circuit fault. In case of multiple problems, the recirc indicator will only blink the code with the least number. write back if this test shows a code and we'll go from there.
