You have a OBD-I truck and not II.
Code 212, Somebody has installed the wrong ICM. They put in a Gray one and you need a Black one.
Code 558 & 332, You also have a bad EVR solenoid.
Code 336 & 542, You have a bad fuel pump relay or bad fuel pump.
Next time be more specific what the codes are, either KOEO, CM or KOER for a more accurate answer.

These were KOEO codes sorry about that. On the fuel pump one? It whines constantly when the key is on. I have changed the relay with no change would that mean a bad silenoid? Would any of the codes be why my check engine light keeps coming on while driving down the highway but as soon as a shutoff the key it disappears until I start driving again.

The 212 code is a CM only code. Replace with Black ICM.
332 code another CM only code, EGR valve did not open when told to. Most likely from the EVR solenoid not working.
542 KOEO, Bad fuel pump most of the time.
Also 556 CM or KOEO code again bad fuel pump.
558 KOEO code, bad wiring, plug or open coil in the EVR solenoid.
It means the fuel pump is running with a high load dragging the voltage low and causing the 542 and 556 codes.
Could be you need a new fuel filter or fuel pump.
Yes they would.
It is the EVR in the the photo above.
No that is the EVP sensor.
