=================================================
OK, game plan is to first ascertain there is firing of plugs, then will
disconnect the injector wires. If I have fire and the fuel pressure holds
up like earlier, then will assume controller is holding injectors open.
If pressure leaks down, then must have multiple injectors leaking (which
I doubt) then fuel is probably leaking by the regulator ( this should not
keep from starting since the pressure is good when pumps are on), and I
must have got it flooded and have never cleaned the plugs. Will get new
set of plugs and some starting fluid tomorrow morning while in town.

Thanks to all for brainstorming, may need more help if controller is
putting too  much fuel in on start
