Check to see if you are getting power to the aldl and ground. The key has to be on to read the codes. Check fuses underhood and under dash

Just to add to this one does your code reader power up off the obd2 connector?When you plug it into the obd2 connector does it automaticaily turn on?

Yes it does get power from the connector port, and it does come on just cant retrive the codes from the port

I would make sure the scan tool works on other cars before going too far in checking wires etc.I have very rarely seen one of those vues that you couldnt talk to the ecm that would start. Also check and make sure there are no broken wires going to the obd2 connector.

I tried it on our honda and it will connect to that ecm, I dont see any broken wires could it be the diag I am using is outdated?

If it works on other cars it should work on yours. Check to see if you are getting power to the aldl andground. A test light can do that.

I checked the signal ground and chassis ground and the battery power with a volt meter and all are good
