If you saying your FICM has 13V cranking that is probably your problem.

If your getting 1900 with the ICP disconnected, that is just the default setting and not an actual reading. With the ICP (injection control pressure) disconnected it has no where to measure the pressure from with out it.

When my IPR went bad, I still had 300 psi, but you need 500 psi to start.

Any smoke out the tail pipe?

through your scan tool with the icp connected...apparently you are not accoding to your scan.

What is your IPR %?
If you have 0 psi, sounds like a big oil leak....STC fitting on HPOP??

what is 13V

100% You have a huge high Pressure Oil leak or bad IPR. Why do you think its getting fuel? With ZERO psi ICP the injectors are not fireing and you are not getting any fuel. Any smoke or vapor when cranking?

Does the oil pressure gauge even register at all, when you crank the engine over? You are saying that ICP psi doesn't even rise at all, even while cranking the engine, correct?

Can we get an IPR %....most likely in the high 80s if you have a large leak.

Might want to apply forced air into the icp port and listen for a leak after commanding the IPR to close, or try to apply 12V to ipr for 30 seconds max. Do a search on testing the HPOP system

Looks like you have a hpop leak. A lot of 05+ have a problem with the STC fitting (snap to connect) I think it is on the pump. You can try using compressed air into the ICP sensor hole and commanding the IPR to 90%, this will close it, don't close for more than 2 min though. Listen for an air leak, may take some time to push the oil out of the lines. Look up this procedure, I have an o4 with dif oil rails. Good luck, you'll get it figured out.
