seems its in a C240 huge truck ? is that your truck, A huge C240?

You have a leaking heater core.

Po300 codes are system generated caused by computer can not locate real failure condition. Coil on plug engines the coil boots fail and wider gap spark plugs wrong spark plugs by design, secondary ignition wires, vacuum leaks, poor fuel quality, plugged fuel filter, low fuel pressure , leaking pressure regulator, unmetered air between mass air flow sensor and throttle body, crankcase ventilation leak.

Most fuel pressure gauges have a bleed valve where you could let the air out.
You could just crank the engine until you get fuel pressure and let the air escape thru the injectors.

No. Most likely it is the blower module. It is on the passenger's side lower part of the dash panel.

left hand side of vehicle behind grill and front bumper bar (receiver drier/filter) for air conditioning refrigerant.
