Check the ESS gap should be .050

It's ok i've used one many times, or a credit card I hear they are close.

If I type in NO TACH NO SPEEDO and filter it for 94-98 almost all of the searches reference replacing ESS. So I have no idea.

But just type in no speedometer and see what the fixes are. The other problems could be the ESS.

I would look for a single fix. It would be odd for more than one thing to go at the exact same time. Not impossible just unlikely

When I junked out my 97 I saved the wiring to reuse and there was numerous grounds that had up to 6 individual wires on a terminal.
