Does your glow plug light come on then go off after a couple of seconds when you turn the key to on? Can you hear the fuel pump humming for 20 seconds after the key is turned on as mentioned? How's your engine oil level?

Oil on the full mark, fuel pump is humming, wait to start light comes on for about 10-20 secs.
Here is some more stats from the scanner all while cranking engine over:
140 rpms
ICP 700-1000 psi
IPR% 15% sitting up to 65% cranking over
EBP psi- 53
EBPV 4.9
fuel lvl inpV- 0
Fuel lvl inp%- 0
koeo test po605 Internal ctrl module ROM error
po470 still stands
po603 is erased and hasn't came back
can I rule out cps since the gauge and the scanner is showing rpm's (150)?

So IPR goes up to 65% and ICP peaks out at 1000 or less? Try unplugging the ICP sensor and see if that helps?

Still got the scanner handy? Watch voltage while cranking. Below 10.5 volts we've seen issues where the IDM would not fire the injectors. Low ICP is still a concern. How full is your engine oil? Any blown fuses?

If you're not getting any white smoke while cranking the injectors are not firing. Check the IDM relay fuse under the hood. Fuse # 27 - 30 Amp Maxi.
