I put a test light on the injector ground wire, and the other end of the test light on the battery positive, and it didn't blink with the engine running. It should flash pretty much in sync with the RPM's of the engine. It didn't, now what should I try? I Ohm tested the connector it matched #2 connector, the needle moved to the right. On #3 the ohm test the needle didn't move.

Because of your inexperience in testing you have now taken out the PCM. YOU DO NOT USE A TEST LIGHT TO CHECK THE INJECTOR PULSE. You use a NOID LIGHT. Do not test something if you do not know how to test.
