I use to drive this fantastic car everyday. I let it sit up for 2 years and would preriodically crank it up for GP. I didn't crank it for a while and now it turns over but doesn't crank. I changed the fuel pump and fuel filter last night with no better results. When I spray starter fluid through the breather unit, it cranks for a minute then turns off. Do I have a separate fuel pump switch and if so, where is it. I am pretty good with vehichles but this one has me stumped.

Check fuel pump fuse and relay are good. Check for fault codes on pcm

Fuel Pump
Electric fuel pump is located in fuel tank. Fuel pump receives power when PCM provides ground to fuel pump relay. When power is supplied to fuel pump, motor and impeller inside pump turn. This causes a pressure difference to occur between both sides of impeller. When fuel is drawn through fuel pump inlet port, pressure is increased and discharged through outlet port.
The fuel pump also incorporates a relief valve to prevent excessive rise of discharge pressure and a check valve to keep residual pressure in fuel feed line when fuel pump is not activated.
Fuel Pump Relay
Fuel pump relay is energized based upon ignition switch and RPM inputs. Power for fuel pump is supplied by main relay, which receives its power from FI fuse. Main relay is energized for 3 seconds by PCM when ignition is turned on. When engine is running, PCM maintains relay operation.
