there has to be pressure all the way up to the reg and inside the fuel rail. the reg does exactly what its name is....regulates the pressure, but the pump has to be running to create the pressure, backyarder style is to pull of the feed line and crank the motor if fuel pressure is there it will spit alot of fuel out, now if there is pressure and no fuel in the cyliners then you have a faulty cas or faulty injectors

Definitely not normal. The only thing that controls the pressure is the regulator, so pump on means pressure at injectors, its notlike the ecu can somehow drop the pressure when the pump is on.

Had this car actually run previously? sounds like you have some issues

Well I sorted the fuel out had a blockage in the old fuel filter god knows how old it was and it doesn't sound like a wrx anymore with the new MAF so I'm pretty happy. Next thing is the car makes power and pulls up until around 4k then it's just like dead revs and has no power. It idles fine and revs fine in neutral any ideas?

      Rear subframe stay bracket bolt removal issues

      Yes. Probably, given that there is only access from the bottom end of it, go with a drill bit. Don't start too small. 7 or 8mm is probably the right size. You want something that can make a big enough hole to do some damage, but not so bit that it clashes with the steel or binds up and breaks your wrist. A slow speed is probably a good idea too. Once the rubber is destroyed, you then have to get the crush tube off the stud, which will be the whole heat/oil/cutting exercise all over again, but this time with the need to strictly avoid damaging the stud (any further than the corrosion might already have done.

      We replaced the connector just because we could and it was still there, once we swapped the injectors around it stopped. The injectors were something I had thoughts of replacing even before I first started the engine and in hindsight I should have

      Not too sure just yet, want to have a go at doing what I can myself, but to start with want someone to cast their eye over it tell me what needs doing to get it running and back on the road, so anyone with great overall knowledge would be ideal.

      I personally would go with cutting out the rubber. Then deal with getting sleeve off separately. Rubber can be painful to cut, it loves to jam up cutting tools. I normally have success with drill bits, deburr bits, angle grinders, jigsaw, reciprocating saw, and never forget... fire. Obviously different tools won't work in all locations you're trying to work with, and you need to be comfortable with each. You personally may be happy slowly slicing it out with a razor blade, if you are, go for it with one too! Feel free to wait for others to weigh in also on their thoughts.

      So ... I got everything disconnected and started dropping the frame. Three of the four mounts started to come down but the fourth one (the one with the nut that gave me all the trouble) won't budge. The inner metal sleeve stays up tight against the chassis rail although the outer part of the mount drops a bit (and can be levered quite a lot more) but it's just stretching the rubber bushing. So I reckon there's some serious corrosion inside the inner sleeve and holding it tight to the lug at the top of the bolt. Tried everything I can think of so far: penetrating oil, whacking the top of the sleeve to vibrate it and wedge a screwdriver blade in there. I also tried to turn the inner sleeve a bit by hitting it with a chisel at the bottom. It's stuck solid. What do you think about cutting the rubber with a blade so I can drop the subframe around it anyway. Then worry about getting the inner sleeve off after? Will that work? Is it gonna give me even more problems?
