Replaced computer but still cant get spark.

If you turn the key on and do not hear the fuel pump run at all after you have replaced the computer then i would look at the (ASD) relay (auto shutdown relay) for the problem. Remove the relay from the power panel. To test the relay,use a ohm meter and connect one end to the #85 and the other end to #86, the resistance should be between 70/80 ohms. Then check continuity between terminals #30 and #87a. The meter should indicate continuity. Then check for continuity between #30 and #87, the meter should not show any continuity. Then connect a jumper wire to terminal #85 and negative post on battery and connect the other jumper to terminal #86 to the positive post of battery. By doing this it will energize the relay and during this time connect the ohm meter between #30 and #87. This should show continuity. If not replace the relay. Hope this will help you.
