You have an Optispark distributor, make sure all connections to & from computer, distributor, ignition module, and coil are in place & in good condition. Also scan the car for codes, they ma give a hint. If everything looks OK, you will need to do some basic trouble shooting, & go trough the whole ignition system one component at a time. Get a maintenance manual.

 

ok thanks
