S25 SRT

a friend of mine fitted some equal length headers and where the thread was for the lamda sensor he fitted a planking screw as its on the downpipe. the screw blew out and he didnt realise to start with but now the car doesnt turn over when starting up!
cel code 23 and 11 or 12 come up on ecu test

any ideas, I think the 2 codes are ignition and maf sensor?

quick rplys appreciated as he is off overseas tommorow and i gotta get it to garage 4 him.
