Well to start, I bought a car with rod knock and had it rebuild. New pistons (20 over), rods, bearings head and block decked and lapped and a Titan metal head gasket. I got the engine in the car last night, primes it by unpluging the coil pack then went to start it. It tried to start and then after a couple of tries it did start, idled REALLY rough around 300 rpms and i had to keep giving it gas to keep it going. then it died and now all it does is crank but wolnt fire. So today I wend over all the grounds, fuses, connections, chacked and rechecked the CPS and the timing it everying checked out except i didnt have any spark . An I cant for the life of me figure it out. I guess what im really asking is if anyone of the supra genuses on this board has any suggestions or answers to this problem.
