The fuel tank pressure sensor on your 2001 Oldsmobile Intrigue is located on the top of the fuel tank, attached to the fuel pump module. There may be an access panel in the trunk (near the rear seat back) which you can remove the access the sensor.
Thanks for the reply. My Intrigue urns over several times before it finally starts. I replaced the ignition switch and it didn't help. So, I'm going to replace the Evap sensor, then fuel pump and lastly the crank pos. sensor. Is there anything else? :-)
