1983 XJS, Bottom line Car starts on time all the time revs up nicely. After warm up I shut down. I go to restart 2 minutes later, will not start. I pull the CTS plug and jumper it Shazam car starts immediately, revs up all seems normal. I shut down come back go to start, no start. I remove jumper plug back in SHAZAMM car starts immediately. Any recommendations? have anyone seen this before? the wire harness (plug looks a little shabby) I will replace the plug and CTS (again). New fuel Pump, Control Module, Coil, plugs, Filter.
