Simple question, maybe not a simple answer, can't find it anywhere.
I've done the work to start and drive my failed 2013 JSW HPFP to the dealer for buyback, the pump cratered a week before the set date, and only 34k miles. Skipping the details, it didn't start, and I'm trying to figure out why. Specifically, I'm not sure the replacement pump is actually making the pressure and charging up the rail to proper pressures, and I want to verify, but don't know how. I got VCDS for this job, and it showed me a P0087 code, but not sure how significant since this is a non-running car, just cranking. Can I use VCDS to legitimately test this, or ???
I used Measuring Blocks and graphing to observe pressure during cranking, but nothing. Yes, the system is all primed.
I'm hoping there is a "clever" way to validate that the pump is actually doing what it should be, so that I can see my next move. VCDS or otherwise.
Thanks.
