Fuel delivery issue, engine not starting?

This vehicle listed above is a S model turbo. A friend of mine had it and it was driving for 20 miles then won't start the if you leave it a while would start and stall or drive, just random.
Codes are attached when it was running, now it barely wants to start but won't like it's out of fuel. I removed the tube going to throttle and sprayed starting fluid and it also wanted to start, a bit better but cannot confirm. He was told a fuel pump.
But isn't there a fuel pump in the tank and then the high-pressure pump?
I noticed the hpfp is not something in have seen before, looks different like its aftermarket. So am not sure if it's the tank pump or hpfp.
Here are also some numbers while ignition was on, could not get any numbers while running because it won't run. If I need to test fuel pressure where would I do it at? And how much should it be? Also, when I scanned it now after I removed the boot to the MAF sensor I noticed this code 37de not sure if it has anything to do with the issue.
