Turbo won't start is a classic issue. There are several items to check. We have a thread dedicated to it on Pelican
http://forums.pelicanparts.com/911-9...snt-start.html
But here are a few things to check:
Yellow relay in engine compartment (I think it is yellow - I switched to EFI a while back and memory may be fading, but think it is yellow)
boost sensor connection - it is on the magnesium recirc chamber
fuel relays in the front trunk - best test here is when you turn the key you should hear BOTH fuel pumps running. If you do not, then check the fuel relays.
If you still get stuck, give me a call 240 876-1305 or drop a line. Not sure where you are located but if close by I am happy to drop by and help you figure it out. It will be straightforward assuming mice have not introduced other variables.
We need to get you to swap out all that overengineering for EFI!!
