Default 991 C4 Cranking but not starting.
So this morning I started the day poorly. Got into my 991 C4, turn the key and the car cranked over and over but didn’t start. Tried a couple more times with the same result. It cranks hard without any sign of battery issues. I drove the car last night and it worked perfectly with no signs of any incoming issues. Any ideas before I call Porsche for a flat bed. The car is in my garage which isn’t too easy to extract.

Ignition fused blown? I know this is a different car, but my truck did the same with the ignition fuse pulled. I was working on it and had the fuse out. The truck would just turn over and over but not start until I put the fuse back in. Just a guess.

Do you hear the fuel pumps kicking in?

Is it super cold where you are? It's zero here.

If you were low on fuel you could have a freezing issue? Might be a stretch.

Opened the door and turned the key this morning. Heard some rumblings from the front of the car but didn't hear the "spray noise" from the rear of the car that you usually hear when doing that.

Good thinking but Seattle isn't too cold currently. My garage is around 60 degrees F and it has full fuel.

Good call! I'm going to look at the Fuse box and see if I can find the one for the fuel pumps.
