We had a similar NO START, and replaced the coil, then Cam, Throttle position, and Crank Sensors. I never really knew which was the cause, but I think it was the cam sensor and/or wire connections. Wire brush all ground straps you can find in the engine compartment. especially the ground for the ECM. knock on wood, we're going strong 10k miles later on our 1995. I can't stress the importance of good grounds, and good voltage where needed on these cars.
