Welcome to this forum! I've moved your thread into the EEC-IV section. Check the list of code definitions on the top of this section.

thank you brooklyn

When you get several codes like that, SOP is to resolve the KOEO codes first, then the KOER codes, then the CM codes (see my notes on pulling EEC-IV codes if you don't know how to distinguish the types of codes). Comments on individual codes in no particular order:

1) KOER 538 is almost always operator error during the test. Review the test instructions and repeat the test, paying particular attention to the "goose" test portion.

2) KOER 412 is often not very helpful. It seems to mean simply that the engine wasn't running quite right (usually you already know that). I probably wouldn't worry too much about this code until you've resolved all the others.

3) CM 214 is usually associated with the camshaft position (CAMP) sensor circuit, assuming your '93 is SEFI with a CAMP.

4) KOEO/CM 543 indicates a fault in the fuel pump circuit. Exact diagnostic steps will depend on whether it is a KOEO code or a CM code.

mr shorty how would i check these test on number 3 and 4 what are the proper steps to fix these issues i really need to fix it soon so i can get my smog my truck didnt pass due to check engine light :[

Exact approach to the 543 will depend on whether it is a KOEO (hard fault) or CM (intermittent fault). Does the truck run (which indicates that the fuel pump is working)?

I'm not familiar with the diagnostics for a CM 214 (my '92 doesn't have a CAMP), but it seems to be fairly common. With the right search terms, you should be able to find several discussions on this here.
