| Other Fuel System Pump problems |
Vehicle start then die or just crank and no start. At the time problem thought to be fuel pump relay. Immobilizer was checked but nothing done. Immobilizer continued to be a problem (after warranty expired); keys have been replaced/recoded, immobilizer control module found faulty and replaced, antenna ring found faulty and replaced. This is a safety issue because there is no warning prior to this occurring; it just will not start when the key is put into the ignition (could be day or night - you are just stuck!) recently, on 7-16-2012 the vehicle repeated this action three (3) times on the same day. In the last two (2) months I have recorded not less than ten (10) incidents. Had I called for a road assist each time I would not have any more available calls. For some reason the transmitter and receiver (transponder) are not in synch (anti-theft device is overdoing its job). Volvo. Com was contacted but so far have not done anything to address this. This is definitely a safety related defect and a pricey one.
