Hello 986ers! Hope everybody’s staying safe with their families!
I have an ‘01Boxster S 6 speed 104K that cranks and won’t start.Went to work, 8 hrs later it wont start just cranks. No warning,no CEL,no codes.Runs great prior.I’ve been reading forums,watching videos with no success so I joined this forum and hopefully somebody had already come across this issue.Battery is new,checked the fuses,relays,CPS,spark,starter,MAF sensor.When I turn the key On It sounds normal with the whirring sound coming by the fuel tank. That’s the Fuel Pump turning on right? Tried to jump the fuel relay socket and I don’t hear the fuel pump run.No fuel going to the line.Checked fuel pressure, none. So I thought it was the fuel pump.Installed new fuel pump and still the same.checked the old fuel pump connecting it directly to the battery and it runs.

Is there anything else that controls the Fuel pump? It looks like something hinders it from running.

I’d appreciate any input very much, Stay Safe everyone!
