    Thought it was a fuel problem. Replaced fuel pump and relay. Found out I have no power at injections with key on and I have no spark. Changed ignition module and still nothing? Any ideas as this parts trial and error is getting expensive. Thanks.

    Make sure that you're getting 12 volts to the distributor. The injectors get their signal to fire from the ignition module. So if that signal isn't generated, then the injectors won't spray any fuel. /forums/images/icons/frown.gif

    did you check the coil? What about the pick up coil in the distributor? Not too hard to replace either...are you getting a spark?
