Hi stevesS10 and welcome to 2carpros
The fuel pressure is fine -have you check for injection pulses meaning the injector/s are opening and closing if not fuel is not being delivered to the cylinders

SORRY BOUT THE DONATION THING, ILL DO BETTER NEXT TIME . AFTER ALL I'M(WAS) DRIVING A 92 TRACKER. NOT SURE ABOUT THE PULSES I WAS UNDER THE IMPRESSION THAT A GOOD COIL MEANT GOOD PULSES. I GUESS THE ECM COULD BE SCREWING UP THE INFO TO THE INJ.

Check if the injector has power-if it has the ground drivers of the computer is defective
