Don't know what you mean jump fires. But first check to see if the distributor gear is still locked in by taking the cap off and try turning the rotor. If the rotor turns then the pin in the distributor shaft has sheared & needs replacing. Then after checking that and it is ok, then pull out the Ignition Control Module, and the coil, then take them to Auto Zone to be tested.

Faulty distributor hall effect pickup?? faulty wiring from distributor to ECM assuming its EFI. If it is point ignition then take wifes fingernail file(paper one) and file contacts.
