I recently bought a federal owned 1985 Vanden plas! I cranked the car, but the coil seems to not be working! One of the wires connected to the coil came off, the wire sparked when it was next to the coil! I need some help, should I replace the coil or what? And what websites can I find jaguar parts, like body parts, trim, interior seat covers, pretty much everything to restore a car?
