Rb20 Problems With Fuel Pressure Vaccuum Line.

[odessy]

Started the car today and it was idling normal and started struggling and the revs dropped. I gave it a little bit and it was struggling to rev and cut out. Now it will not start. As this was happening I noticed the fuel pressure regulator vaccuum line came off at the manifold.

I put this back on and didnt help. I can hear a sucking sound through the intake or ic piping somewhere like its leaking and the boost gauge was sitting around - 5 to -10 psi where it usually sits at around -20 from memory.

What have I done?

Some hose is off somewhere.

I think I knocked the vac line off when I was removing the oil filter... Derp. By running it with the fpr vac line off could I have broken anything?

It shouldnt have damaged anything, there is also a really little vacum hose under the manifold, its only very small and makes that hissing noise, it probably wasnt the one u knocked off but for the record anyway.
