96 Barletta 3.1 just died. New fuel pump. Only runs on ether. Has pressure on fuel rail. Pressure regulator or ECU? Is there a relay to energize the injectors? Checked all known fuses...all good.

When you are trying to start it can you hear the injectors pulsing. Have someone turn it over while you hold a piece of PVC pipe up to the injectors. You should be able to hear them pulse. Or remove wires and test for pulse with multi meter.

okay, you've a MAF sensor AND a MAP sensor...your diagnostics should have thrown codes up for these...invest in a handheld scanner for fourteen bucks and we can see which sensors are makin' you huffin' ether there (very unhealthy for the motor as it STRIPS away any lubircation)~save harmful~...your principal combustion measuring devices probably need to be looked at~
