AAG gti ecu non starter

[soniquethedog]

hello , i have had a 2.0 golf gti 8v fitted to my t25 , i recently had a socket fitted to the ecu so that i could fit a performance chip , but when i re installed the ecu it wont start , even with the old chip back in , it turns over but its as tho the immobiliser has kicked in , i have checked the fuel pump relay and there is no voltage at the coil to pull it in , the wirng seems ok , when i turn the ignition on the pump normally primes for a second and its not doing , any ideas ?

cheers dave

have you got the diag socket wired up..

can you communicate with it via vag com or other diag software ?
was the chip orientated correctly ?
whom socketed the ecu ? how was it done

hello , brickwerks fitted the wiring and it worked before then the auto electrician fitted the diagnostic plug , but it doesnt seem to work anymore , vw parts international fitted the socket , not sure how they did it sorry , the chip only fits one way as it has a corner missing
