Fuel pressure is regulated by the manual valve on the end of the rail, and you can recognize it from is 1.5" round appearance, with an in and our fuel line, and a small rubber vacuum hose going to it.
But first you put a gauge on the fuel rail. Should be around 30 psi I think? More when you accelerate, because the vacuum line is supposed to make it do that.
But your problem is more likely the ecu is in limp mode, due to some error condition it thinks is dangerous. Is the check engine light on? Seems like it should be? Have a free read done at any parts store.

Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.

2000 Volkswagen Passat 4Motion 2001 passat v6 misfires at low rpm while trying to accelerate

When were the sparkplugs,airfilter changed,is there damp in the coil packs or the seals worn allowing in damp.The maf sensor(mounted in airbox top) may be faulty or the throttle throat may need cleaning.Fuel contamination can play a part, how old is the fuel filter as they should be replaced every 2 years.Check that all vacuum pipes are secure and not cracked as leaks can add to the problem.

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.
