I have a 1988 Toyota Supra Turbo. When I bought it, it had a blown head gasket. I had the head rebuilt and put it all back together. I have been able to time it twice but after each time it will not start the following day. Now, it will turn over but not start. It also it not getting any spart to the #1 spark plug. The car has been running twice for 10-20 minutes each time so I know it runs... What could be the problem? Thank you. Lindy.
