I didn't take a pic, but what is the thing under the driver side seat on an '89? It's mounted to the floor, looks like a relay of some sort.

I remember the fuel pump relay was under the passenger seat on my '93.

I believe it's still the fuel pump relay. Disconnect it and see if your fuel pump works?

My fuel pump relay was under my drivers seat on my 92. Is ther anything under your passanger seat?

It is indeed the FP relay. It had moved next to the WOT relay on your '93, which is why it's a new find for ya.
