Hello, several issues can cause no spark, but, I don't know why that would effect the gages, unless there is a problem with the ignition switch.

Have a helper crank the engine, check for primary voltage at the coil and injectors. If there is none, check the voltage circuits going to the asd relay. You can unplug the relay, turn the key on, you don't have to crank it, use a testlite on the terminals where the relay plugs in, two of them should be hot.

If your saying, two of the terminals at the asd relay are hot, with engine cranking, no, I don't think it is the switch. Maybe I didn't understand your last post?
