Last few days noticed my 03 Boxster S seemed just a little hard to start. Needed maybe one extra rotation to light off. Was suspecting a starter motor or clutch permissive switch. Was bracing for a complete failure so I would know what was failing.

Drove into the garage yesterday and parked. Later in the evening got my complete failure. Went to drive the car and it cranked but wouldn't start. After a short contemplation I sprayed some starting fluid into the air intake after removing the air filter. The car started and ran briefly. I have a fuel issue. Checked the 25 amp fuel pump fuse and it was good. Row C number 4. Pulled the fuel pump relay and coil had 65 ohms and contacts made. put 12vdc on the coil and read the contacts as closed with my multimeter. Made a jumper and jumped the relay socket and no pump sound and no joy. pulled the battery and found the fuel level sending unit locking ring broken. Pulled the sending unit and pump. My Boxster is broken until I get the new fuel pump and locking ring I ordered. Should be back in business by the coming weekend. This website and you guys were a big help to me in getting this far today. Thanks.
