Hi, I am Mike, welcome. I'm reviewing your question.
Fuel pressure on that isn't that much, only like 10 psi or so. If you have fuel pressure, you probably don't have the fuel injectors working. Check the fuse/s.
See if it starts up for a few seconds with a few shots of starting fluid or a shot glass of gas poured into the throttle body. If it does, then it's most likely the fuel injectors either have no voltage to them, so you could check with a voltmeter or 12 volt test light with the key on run, or that the fuel injectors do not pulse, meaning as long as the fuses are ok and the ecm is getting power and ground it could be faulty fuel injector drivers inside the ecm but let's rule out the other things for right now.
They are fuses ecm1 and a ecmb fuse.
