1986 944 NA injectors not firing tried all the tricks

[skigolfnut]

Long story but stay with me,
My daughters joined the Navy and left her car with me to try and keep it running,
I would start it about once a month or 2, and it would start fine and run in the driveway, Finally the battery died and I did not start it for 6 months, new battery and it turns over but no start, checked the fuel pump and it was not working, so I replaced the fuel pump and the DME relay and the Fuel regulator,
I am getting good fuel pressure up to the fuel rail and past the regulator to the tank return, but the injectors will not fire?
i can squirt gasoline in the throttle body and the car will stay running as long as i spray gas in there,
I pulled the alarm box and was going to do the by pass tip but it has a aftermarket alarm called THE UNGO BOX in place of the stock alarm, it has a red push button that is supposed to reset it but when I hook up its red hot wire to the battery the alarm siren goes off, the red hot wire to the alarm has been unhooked for a couple of years and I we have never had a problem with it before,

I am stumped, if my crank sensors were bad it should not stay running correct?
doesn't that tell the spark plugs to fire?
any suggestions would be great,
