Replaced my ecu and my 2001 astro van turns but won't crank

This answer was rated:

replaced my ecu and my 2001 astro van turns but won't crank it's throwing codes of p1518 & p1336
JA: Have you checked the fuel supply? And are all the spark plugs working?
Customer: yes I have
JA: Are you fixing your Astro yourself? What have you tried so far?
Customer: I have reset the security code. check all the fuses
JA: Anything else you want the mechanic to know before I connect you?
Customer: may be how to flash this ecu myself

Where did you get the pcm from? Is it new or used? Did you have it flashed before you installed it?

Customer: replied 2 months ago.
I got it from Advance Auto. new. I was told there was told that after taking it through the reset process it should work

Can you please recheck the codes? code p1518 is not a valid code for this van.

Customer: replied 2 months ago.
it says (P1336 CKP SYSTEM NOT LEARNED) AND (P1518 ELECTRONIC THROTTLE MODULE TO THE PCM)

What are you using to retrieve the codes?

Customer: replied 2 months ago.
CEN-TECH OBDII/EOBD AND A INNOVA 3100/ABS

I hate to say it but that is a generic code reader, and may be giving you a false code. The code p1518 does not exist for this van. Why did you replace the pcm in the first place?

Customer: replied 2 months ago.
IT HAD NO COMMUNICATION WITH THE VAN ANYMORE. THEY WHERE GETTING NO READINGS AT ALL
Customer: replied 2 months ago.
A MECHANICANIC SAID IT NEED TO BE REPLCED
Customer: replied 2 months ago.
HELLO

Would it run with the old pcm in t?

Customer: replied 2 months ago.
NO NOT AT ALL

Can you clear the code and try to start it again and see if any of them come back?

Customer: replied 2 months ago.
THE SAME TWO CAME RIGHT BACK

I hate to say it but I think the pcm was flashed incorrectly. you will need to take it back to advance and have them send it back and have it flashed correctly.

Customer: replied 2 months ago.
IS THERE A WAY I CAN FLASH IT MYSELF

No. You have to link into GM's main frame to flash it, as well as have the hook ups. You will have to send it back, take it to your local gm dealer, or see if you have an auto electrical repair shop near you that can flash it for you.
