96 V6 ignition problem - BaldyBob
Hello, 1996 V6 Vectra, has an ignition problem, firing on 4 cylinders, has been plugged into Tech 2 which only indicated No2 and 5 cylinders not functioning. All leads checked individually and 1,3,4,6 all sparking but not 2&5, coilpack removed and coil that supplies 2&5 cracked and melted. Coilpack replaced but 2&5 still not sparking!, any suggestions welcome, have been told this could be an ignition amplifier problem, but do have a clue what or where this unit is on the Vectra.

If I recall the V6 models run a Bosch motronic system where the ignition coil driver circuits are part of the engine control unit.This is located behind the air intake plastic cover in front of the pass wiper arm and is protected by a large rubber boot.hth

Hello, i sorted out the ignition problem on the Vectra, when the coilpack expired it damaged the ECU, Tech 2 was showing absolutely no faults, a replacement ECU has the car running smooth again. On trying to obtain a replacement ECU i was assured by quite a few "gents" that all V6 ECUs were interchangable!, this is not the case!. The ident numbers on the ECU body must match ie HH for HH, GT for GT, etc, AVS Vauxhall in Nottingham were very helpful.
