I would test acctual pressure at the port ans see what ya got. FYI you will have to go to the local hardware store and get a 90* street elbow and put it between the schrader valve and the fuel pressure regulator. A guage won't fit the way it is cuz the lift ring is in the way.
Also, check to see what kind of voltage you have at the batteries WHILE cranking. You need to have at least 10.5v for the IDM to fire the injectors. You might also check the oil level in the HPOP (big sqare box on front of motor), I belive it has a pipe plug in the top and a 1/4" ratchet will fit in the hole. You want the oil level around 1/4" or so from the top. Also check to make sure the oil pressure is coming up while your cranking and that the tach is reading.
FYI-WD-40 works good as a staring aide and isn't as volitile as eather.
Let us know what you find and we can go from there.
