Hi BenzGuy--------------The 280 ZX Turbo doesn't use an ignition module on the distributor. Instead, there is an ignitor that is mounted on the coil bracket. It's a round metallic piece about an inch in diameter. This ignitor takes the place of the ignition module used on the n/a ZX's.
My '82 280zxt won't start at all. It stopped one day when I was going about 30 mph. Acted like it ran out of gas. Replaced coil and checked everything obvious. Hate to change distributor until I'm sure that is the problem. Can this module by bypassed to check it? A tech at Nissan recommended it, but that don't sound right for an ignition module.
