Have a friend crank the engine and stand at the tail pipe. If it smells like fuel then it would seem your getting it but if your getting fuel it should be running.
Clear the codes again and crank. that 1280 will probably come back. If it does we are stuck until we have some way (scanner or manual gauge) to look at HPOP pressures.

if you can get ahol dof a good scanner it would be much easier, if not then you need a gauge capable of 4000 psi or more. i cant recall the exact size of the threads in the head but there are 3 plugs in each oil rail, pull one out and take it with you for the thread size. and remove the oil line to each head to get the size to block off the pump to isolate the heads

Gauge or scanner?
Gauge yes thats good, Scanner its good but it also could be wrong (bad sensor/wiring/pcm) but it would point us toward the fuel supply in any case.

IIRC If it is a scanner ,It could be a false reading,it is reporting what the PCM is asking for or expecting to see with a closed IPR ,,guage is more accurate....
