"Luckyman"...

If you've time, just keep troubleshooting. Take detailed notes... what you did... what didn't work. Keep searching these pages. Someone else has been there, and maybe shared a solution. If you exhaust all efforts, then you can source an indie. Good luck, er, best wishes.

Luckyman, you have to be patient and do a thorough troubleshooting, eventually you will get the car running

Since you can crank the engine, then I would next check for fuel, can you hear the fuel pump running? If so, then you check fuel pressure and flow, for this you don't need any fancy tools, not sure if where you live the auto part stores have tools that you can borrow or rent (for the fuel pressure tester, for the fuel flow you need an empty container and a watch.

Note: All cars are supposed to have a safety switch that cuts power to the fuel pump when you get involved on an accident, but don't know how the Porsches address this issue (someone that knows please share your comments)

After confirming that you have fuel then you check for spark, I am sure that you know this but by a process of elimination you will find the cause, good luck!

Porsche does it thru the crank position sensor; of the DME does not see engine rotation, it shuts off both the fuel and ignition systems.

But as his problem is only on one bank of the engine, it ain't the CPS.

The safety systems that I was aware of, have a type of a 'safety switch' that opens upon a measured impact or g-force, that sometimes get triggered by hitting a large pothole..

Which is why they chose to use the CPS, as these cars are often under high G loads on both the track and the street. The only impact activated sensor in these cars is for the air bags.................
