Ok So you said that you replaced the OptiSpark?

Is it giving you any codes? if it is giving you any timing reference codes it is the opti or the crank position sensor, but if its not giving you any codes my money would be on the Coil and or the ignition module.

Also on the optispark it has the long harness that goes down to it, if that harness is damaged it can act like if the opti is bad, but in reality its the harness.

i replaced the fuel filter coil and module yesterday and it is still not getting any fireit will fire once every two or three hours but will die in 5 to 10 minwill that still be the opti spark or crank position sensor

check that harness going down to the opti, you know the one on top that pops up from behind the water pump on the right side of the car
