Check the fuel pressure

sounds like a wire is disconnected somewhere, check for melted wires, or one that has a lot of grit or corrosion on it. Use a good electrical cleaner. Clear codes and retry your diagnostics test.

Check the headlight switch. The power goes from the fuse to the headlight switch and then to the dash and running lights.

you have codes related to the pcm, transfer pump and a vehicle speed sensor. these could be related or all individual issues. related issued could be wiring, untill you start doing testing it will be hard to tell.
start cheap and test the speed sensor first, then you can clear the codes and continue on any codes come back.


Disconnect the PCM harness connector(s).
Disconnect the Vehicle Speed Sensor harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the 5 Volt Supply circuit between the VSS harness
connector and the PCM harness connector.
Is the resistance above 5.0 ohms?

the code is map sensor too high, too long. certain programmers with boost foolers can cause this. if running a programmer disconnect and if problem isnt fixed replace the map sensor.

it is in the rear of the timing cover, below the injection pump and above the vacuum pump. hope this helps!!

injector pump bad change it

No bus error code has nothing to do with your fuse panel this is a ECM /ECU error code... sorry but get ready to spend some money for a new ECM
