Fuel puddled in intake
Ok here is the back story.
Hard starts when warm, progressively getting harder. When it does start its because I crack the gas pedal and it barely runs for a few minutes, then all feels fine. Last time during the hardest start yet I noticed the fuel pump got really loud when running. This led me to the fuel accumulator since it fits the bill for the warm start issue ive been having and the sudden fuel pump noise. While replacing the accumulator I took off the upper air intake and there was fuel puddled in it. If I remember correctly this is a sure sign of something bad, I can't remember if it's the WUR going bad or somthing else and I can not seem to find it again in the forums. Any info/links or experience would be graciously taken.
Pre thanks!

The cold start injector sits right under the T/B. When it goes bad it leaks all the time.
You can troubleshoot it by replacing the banjo bolt in it's supply line (found on the front of the fuel distributor) with a solid bolt,which will block off the fuel supply to the injector. No more fuel puddle means the injector is bad.

That's the air cleaner. Now we're talking apples/apples. Between the fact that your car will barley run and the fuel in the air cleaner, I bet that you have a ruptured diaphragm in the wur.
There's a rubber vent line that goes from the wur into the air cleaner in case of a diaphragm rupture. Better remove the wur; get it rebuilt as an adjustable one and since you run higher than stock boost, get a heavier diaphragm installed. You can send it directly to Brian Leask (Google adjustable wur) or to Brian Boddart (RarlyL8.com) and he can do an exchange with you.

On it and thanks Metal guru. I will pull it tonight and do some research on digital WURs. Chances are i will send it out Monday for the works since I don't recall anyone raving over the digital one.
Thanks again.
Thanks again.

The possibility of adjusting control pressure with a laptop is appealing but IMO the digital wur is not and may never be ready for prime time.
