I had similar symptoms, spark but no fuel coming out of the injector lines and no start when I poured a little fuel in the air intake, and what I did makes no sense to me but I unplugged the OVP relay, jumpered the voltage pins and it started. I then plugged the same OVP back in and it has started ever since - about 2 weeks now. My 91' 2.3 has the OVP relay behind the battery - mine has 2 red fuses in the top of it. You can jumper pins 30, 30a, 87e, and 87l together to bypass the OVP function (put battery voltage everywhere it needs to go). The side of the relay has the pin layout on it. Good luck.
