ok well iv just replaced my 1.4 auto with a 1.6 manual changing ecu and wiring. seem to have a problem with i believe the immobiliser. when i turn the ignition on the pump primes and when i crank it i have spark. now for the problem. my injecters dont open. iv tried grounding a24 pin on ecu as per another thread but this changed nothing. iv checked and there seems to be power going to the injectors but the grounding seems to be the problem. can anyone offer some advice as i am now stumped.
