Looking at a '98 12v tonight with the same issue. Forgive my ignorance, but what is ESS? Will start with checking for grounding wires first. Helpful thread, thank you!
Engine speed sensor, or most call it a crank sensor, but all it is doing is pciking up a tach signal... to let the pcm know the engine is running etc.
