Ive got a weird problem with my car whats been going on for a few months now.

i got a new chip and the car wouldn't start.

but it works fine on a spare p8 i have

the chip was replaced but the same problem persisted

The ecu went to the tuner and was tested there on a car there and all was ok, but it was suggested i replace the baby board as there was a suspected intermittent fault with it and i might want to replace it for ultimate reliability.

so..

ecu was returned and it still wouldn't start

after weeks of waiting for a "different tuner" to send a new baby board it was fitted and..












it still wont start


what happens is the ecu monitor shows no faults, the is no fuel pump "prime" but dose clunk and powers when the engines turned over

BUT WORKS FINE WITH THE P8


Any sugestions ???

and anyone ooop north who would kindly test my ecu for me ??

its a late 4x4 l8
