Great to hear! What did it end up being?

Now you just need to figure out which cylinder is down and why. If you messed with the CAS, make sure it's in time.

Thanks you soo much!!!
It turned out to be the CAS... There was a loose wire soldered dodgy
The car runs fine now and runs on about 2-3 pound of boost!

Glad to hear it!

We had the same thing happen at the shop. Z31 came in and wouldn't start at all. Spent a few hours testing various things only to find out the signal wire for crank position on the CAS was broken. Fixed it and it fired right up! The wiring in these cars is so old that it's really not uncommon (hence why I kept staying to check the wiring).
