The engine starts in "open loop" mode with factory default settings in the ECM. When it warms up, it goes to "closed loop" operation and relies on the O2 sensors to adjust timing, fuel, etc. Check for error codes (DTCs) using an OBDI code checker, or consider replacing the O2 sensors.

MAF is probably not the problem - sounds like the engine is not getting the fuel it needs to start and either your injectors are fouled or the pressure regulator is stuck - that might cause the hot wires. The fuel pressure seems a bit low, but it should momentarily drop when trying to start the engine.

You might hear a slight to very loud whining or squeal coming from sensor on transmission when you accelerate or your spedometer will be acting faulty if working at all.

There are a range of thing that could cause this. Check the mass air flow sensor if it is dirty carefully clean it... Make sure your vacum lines are in good shape and have no leaks... Also check fuel system from pump to injectors. That did it for mine

I would say, check the engine coolant temperature, if that's okay, check water flow trough the heater core. If the coolant temperature is to low replace the thermostat. If the water flow is to low though the heater core, it must be partly blocked, and should be replaced.

you may have to lift the gear box with a jack or remove the cross member

The only true tools you need is your hands, pliers/blade screwdriver. The fuel filter is located in the undercarriage rear adjacent to the left side of the fuel tank. It is bolted with a singular screw onto the uniframe just to the side of the rear-left wheel. The filter is equipped with quick-release connecters that require a firm grip and tug, releasing the fuel lines from the filter. You might want to use a fat blade screwdriver and/or pliers to pull back the connecters, only don't use too much force as this will crack the plastic keepers, defeating the entire job. Be patient but firm and all will work out.
