Question about 1985 Oldsmobile 98
At the battery there is a tan or brown wire that if you touch it to the pos battery post should make the pump run. This bypasses the relay. Also, you can put a fuel pressure tester on the injector fuel rail - there is a connector that looks like an air pressure valve. Turn on the key and the pump should run. Pressure s/b typically arount 36 - 45 lbs. The motor will run with pressure down to about 28 - 30 lbs although maybe not very well. Below about 24 lbs it will simply not run at all. Sometimes when a pump goes it quits entirely, and sometimes it just gets tired but doesn't stop completely.

You don't have to drop the gas tank. if you pull up the carpet in the trunk, there is a hatch that opens directly above the fuel pump for changing it.
