car backfired a few times than died
ok, long story short, a buddy of mine was driving his Z down the freeway and it backfired a few times then died... we had it towed to my house and we tested the fuel preasure (sits steady at 41), replaced the coil pack, plugs, and wires, verified the valve train was ok, and it still wont run. You can turn the car over and it will start and idle at 200 rpm's as long as you keep your foot on the break. ignition timing was at about 12 degrees. I think it's the opti-spark... any other ideas of what it could be if it isn't this?

Something similar happened to my 94. I was driving it when all of a sudden it back fired and cut off. I tried to fire it up and it would die right away. After a while it would just crank. When I checked there was spark at the coil but none out the opti. Most likely its the opti I would say..

It ended up bein the opti.... we replaced the opti and got new 8.5 wires (the wires were a complete PITA to route) and it fired right up. He said it runs better now than it ever did.
