The fuel pressure (~40 psi) should be maintained for several minutes after the pump shuts off. If not (intially high but bleads dow quickly), there is a leak. The leak could be the check valve in the pump, an injector, or the fuel pressure regulator, or a hose leak. If it's never high to start, then the pump is bad, or there is a blockage. Logical places to look for blockage are the fuel filter and the inlet screen on the pump.
I think you should resolve the fuel pressure reading you're getting. This could be an indication to the cause of the symptoms that you see.

Thanks for your help, I will check everything later today or tomorrow morning. This morning I turned on the van and it works fine, I was maneuvering to make some space for the other car when I put the van in neutral and the started reving up, it was doing about 2000-2500 RPM's, could this indicate maybe a MAF problem? I haven't tested it yet, just cleaned it, I will test it soon.
