Check engine lights HELP

[killab443]

I recently started my car after 3 weeks to find my 3 year old battery had died, would not start with jump cables. I put a new battery in it and started her up. the car would not stay running, I had to give gas to try to make it idle but as soon as I let off the gas it dies. I get a CEL when I hold the gas to keep it running/ I ran the Data Logger adn got the code for airflow sensor. I changed out the sensor for the 2g upgrade I had to put in. Made the harness correctly, checked and double checked each wire,. Installed the new intake and sensor. the car still wouldnt come to life. I was able to get the following codes as I tryed to keep it running holding the gas again:
12 Airflow sensor
13 Air temp sensor
25 Barometric pressure sensor....
Please help im STUMPED
Thanks

ALSO: Caps on ecu were recently replaced and the car ran fine with the rebuilt ecu

All of that stuff is in the MAS...TRIPLE check to make sure you wired the 2G MAS into it correctly (or the MAS is actually bad). Maybe also reset your ECU.

I just checked the harness with my fluke tester. All checks out, even checked it twice. Gave the ecu a reset and still no go...any ideas?

I just checked the harness with my fluke tester...

Not to sound like an asshole, but even if the harness (you DID mean the harness on the MAS, right?) is good, you might have wired it incorrectly, or spliced the wires into the wrong ones on the car's wiring harness.

If you cleared the ECU and it's still throwing those codes you either have a bad MAF or you miswired it.
