Why wont it start if it has fuel pressure but still fires with starting fluid?

Asked by GuruFKRTD Apr 29, 2020 at 10:31 AM about the 2009 Volkswagen Passat

Question type: Maintenance & Repair

I swapped out this motor in this 08 passat. Swap
went well and then I go to start it and I cranks great
but no start! Itll almost start with some starting
fluid. If checked fuel pressure and it has more than
enough pressure! Any ideas?

What’s it mean English language lights on


If you mean fuel pressure at the rail, it probably means that the injectors are clogged or the pulse to them is dead..... The previous answer? I don't know what's going on.

So I got it running but it's got a rough idle! Turned out it was the cam sensor! But the rough idle I think is the maf sensor because when I unplug it it runs better with it plugged in
