No start after storage / after pulled fuel pump fuse - 986 Forum - The Community for Porsche Boxster & Cayman Owners

She turns over but will not start. Probably due to my intervention.

After storage, I turn over the engine on the starter to move oil throughout the engine prior to actually running it

After jogging the engine with the starter I pulled the fuse so that she wouldn't start...there was cough so I made sure she didn't run.

Now with fuse in it won't start at all. I have cranked as much I can on one battery charge and motor duty cycle. Each time I believe I can hear the pump running with ignition on.

Any thoughts?

Maybe time to pull the IT trick. Disconnect the battery and boot the computer?

Yes thought of that.....cycled the batt switch. And now pulled battery out completely for 24....had to recharge it anyway after the cranking attempts

Perhaps I need to connect the battery terminals together to get a reset

Well after 24 hrs any settings stored in memory should be gone and computer should be back to base settings. I think it is recommended to disconnect battery for 20 min to wipe out stored memory. Good Luck!

I hope there is something that will reset otherwise........relay, pump, crank sensor etc??

It is not in a convenient place to work on and has to moved fairly quickly

Sux about the work space. So simple preliminary tests would be to hook up a fuel pressure gauge to confirm pump running and fuel pressure, if no rpm indication upon cranking then CPS could be suspect. Gotta ask if you checked fuse to immobilizer?

It's probably the fuel pump....
