i have a s5 gxl that was org. a na and i decided to do a turbo s5 swap, i changed the ecu and the harness, pressure sensor everything possible except the mass air flow its still the na mass airflow........... so my question is that do anyone out there know it the fact that im using the na airflow the reason for why the car is not starting with the key........and when i pull start it, it starts up and shuts off as if im not getting any fuel.

probably a ground or something is unhooked. if the starter isnt even kicking over, definitly something in the wiring. double check all your connections, from there vacuum leakage and if still no dice I don't know man! make sure you didn't pop the main fuse somehow, make sure your fuel pump is working.

it cranks it just doesnt start......... im currently double checkin the harness, would that air flow meter be a problem.

start at the starter and work your way around the engine. I bet you my lunch money its something easy you just didn't plug in or double check when you installed it
