car won't start.
no fuel delivery.
when we open up the injector lines there is high pressure.
car had been sitting for 6 months.
if we (intermittantly) spray starting fluid in the air horn, car runs great

Start by checking to see if there is power to the injectors. If you have good fuel pressure, that is the only thing that would be causing it not to start. If they aren't getting power, you need to trace the power supply to locate where power is lost. Not a fun job. Also, make sure all the plugs to the PCM are tight and not corroded.
