Jag,
The people on this board are good at what they know and are better at what they don't know. It is a shame that this thread has taken an ugly turn. But it is a funny ugly turn. You mentioned that any suggestion would help. So here is my suggestion.
1. Buy an identical car with out the miss.
2. Test both cars to verify the the miss is in just the original car.
3. swap both engines and retest. Still fails?
4. Swap both electrical harnesses. Still fails?
5. Swap fuel tanks and filters and supply lines. still fails?
6. Swap transmissions if not done with engine. still fails?
7. Swap complete front and rear suspensions. still fails?
8. Swap chassis. Still fails?
At this point I am stumped and don't have a clue what the problem is.
Brain fart: Sell the car with the miss to a roockie Porsche want to be owner and keep the good one for yourself. I hope these suggestions help and happy motoring
