Hello Gary... how are you doing?

I can understand that. Actually, all the works you have done should have corrected the problem. But here's the list why this code shows up. 

1. Faulty crankshaft position sensor

2. Crankshaft position sensor harness is open or shorted

3. Crankshaft position sensor circuit poor electrical connection

4. Signal plate may be damage

5. Starter motor may be faulty

6. Starting system circuit Dead or weak battery

As you can see, the problem can be on the harness itself that's why it's not communicating with the computer and throwing this codes

I strongly suggest that you have the conncection of the crankshaft position sensor inspected. The wire can be broken inside that's why it's causing this issue. Sometimes removing the negative battery connector gets rid of the code ones the ECM is resetted

Yes indeed Gary... that's why it keeps on throwing this codes even with the new parts installed. Should have been running perfectly by now. Is there anything else I can add or help you with Gary?

Yes Gary... the computer is sensing that you have a faulty crankshaft or camshaft position sensor even if it's new because of a faulty or bad connection. If the computer senses this, you will have erratic idle or there are times that the car will not start at all because of no communication of crankshaft and camshaft to the ECM
