2002 Jaguar XK8 V8 naturally aspirated w 90000 miles. A.T. &Amp; typical equipment.
Bought car six months ago & drove it home from Fla. ( To Seattle). Car runs great.
Last week I started car & drove away. Immediately alarm went off for several seconds then stopped. This happened several times in just a few blocks. Turned around & drove back home as alarm continued to malfunction. Parked, shut off & removed key. Waited a few minutes & tried again. Inserted key & rotated but did not engage starter. Alarm went off for several seconds & stopped. Started car & experienced same malfunction.
Am at a loss as to cause. I think car is equipped with inertia sensor. Not sure if this could be involved.
