911SC Starting problem!

[worm]

My 911SC -80 did run perfect yesterday and on the evening I parked it in the garage.
This morning I sense some fuel smell outside the car (but the garage is shared with many other cars so I dont know if it's coming from mine) and now it does not run.
The car cranks and fires and then instantly dies. Tried this 4 times with exactly the same results, then decided to take the train before I will run the battery flat.

I have checked the board but nothing I read fits into my problem.

What might be wrong with it!?!?

It could be fuel pump relay. Run a live direct to the pump fuse and see if it runs like that. If it does check all fuse and relay connections for corrosion and then try a new relay.
good luck

fuel leaking into cumbustion chamber??

If it tries to fire while starter is turning, but dies when ignition switch is released to 'run' position ... and, if your car has a factory alarm with keyed switch in the driver's door, then the alarm control module is highly suspect! There is a well-documented [in factory service manual]failure mode of the alarm module that disables the car from being started!!!

Please read the following thread:

'82 SC Won't run

When I moved the car (by hand) to get better light I found the reason. Someone had broken into and emptied it totally on gas!!!
Thats why I smelled gas around the car!
Put some 10 liter of petrol in it and now it spins again.

The leasson learnt here is that the fuel-meter does not update itself if there is no gas in the tank. Mine was showing 1/3 of gas until it had run for some minutes then it dropped down and the red light came on.

Going to the insurance company and local Porsche shop tomorrow.
