NOTHING ELSE

Hi, Let me get this right.

 

You say

THE SCAN TOOL IS NOT READING ANY

DATA BUT IT'S TALKING WITH THE PCM

 

How do you know it's talking to it if you are not getting any data?

 

If the scan tool is talking to the PCM you should be able to see the live data and monitor the rpm's when cranking the engine. Are you able to do this?

 

Also when you turn the key to run does the check engine light come on?
