Sending you a PM. There was a guy in Atascocita renting one in early 2022 that I used.

DI's can be tricky to diagnose so you really need to go system by system. Start by confirming the air compressor puts out 80+ psi. Then move to fuel pressure. My comments below are from working on my 2000 DI but I think most systems are the same. The air compressor has an o-ring under the...

The service manual (found on Google) has a procedure for dead head testing the air compressor. It should hit 90 +/- 2 psi during cranking.

I used the SBT tool on my 2000 GTX and it worked great. I found a used one on Facebook marketplace nearby. On my GTX, you use the tool to get the engine in the right spot, then the pump bolts on the back without needing further "alignment". I was shocked at how much my original motor mounts...

That pump is specific to DI's, and they are problematic for many. Aftermarket replacement units are even more problematic. Do you have a picture of what you took apart? I have never seen anyone replace the internal o-rings, though it sounds like you have it apart. I would think you could find...

Good work! You have my condolences for continuing to work on DI's. My one and only rebuilt was enough for me!

Check dead head pressure output on the air pump to make sure it is high enough. If that checks out, it points to a bad fuel pump, which is not surprising with an aftermarket unit.

Aftermarket DI fuel pumps are hit and miss, and lots of folks recommend staying away from them. Is it possible the fuel pump drained your battery? Another thing to check is air pressure. Fuel pressure is regulated by air pressure, so if your air pressure is low, your fuel pressure will be low...

I wouldn't. You want the full synthetic oil designed for "direct injection". The (newer?) XPS Snow full synthetic says "direct injection" on the bottle and should be fine.

Check voltage at the battery when it is running.

That is a vent line, see diagram below from the 2000 GTX DI shop manual.

Are you talking about the oil line? You can see it in this picture with the oil line connected. This motor was from my 2000 GTX DI.

Your photo matches how I set my 2000 GTX DI. The 2000 SeaDoo Service Manual actually does not have a photo, but the 2002 version does and it matches what you show.

One way to rule out the air compressor as the problem is to hook shop air to the air line. That is where the fitting @etemplet mentioned can be used or you can hack it together (what I did my first time).
