Where is starter relay switch? 92 escot wagon

It's not in the manual and I can't find the damn thing...I jacked it up to change the oil and every since the fuel cut out switch comes on. when I try to start it.. I tried toto bypass the switch by putting the wires of the switch together it won't start so I" thinkin it might be the fuel relay switch. I looked around the oil filter and don't see any sensors unplugged any other ideas?

What exactly is the problem? Engine cranks but won't start?
In the process of changing the oil and filter is it possible you accidentally disconnected the crank sensor somehow?
Are you getting fuel and spark to the cylinders?
Is the starter even turning?
Is the battery good? Have you tried jumping it?
Give more information for a better response.

The starter relay is built into the starter solenoid. There is no external relay.
