Checking Control Pressures

Anyone have the control pressures handy for an 86 930, approx 75 degrees outside. Starts cold perfect, but been having a hard time starting warm, and also have a fuel smell on acceleration. This weekend went to the NC mountains to drive along the Parkway, and at one point was at approx 6.7k feet and could not get the car to start (warm), had to coast down 3k feet for it to finally start! So, going to start with checking the operation of the WUR first. Going to order a spec book, but if anyone does have the pressures handy that would be great.

Just checked the cold control pressure at approx 75 degrees and it was 2.7 bar.

It could be a leaky fuel accumulator. Try pinching off the hose that exits from the bottom and see if it will start hot (if your hoses are still pliable). If that cures the problem, replace the accumulator.

Control Pressure

Thankyou 930turbo. I was just talking to a friend on the phone and suggested something similar, to disconnect the lower line, plug it, then crank the car and see if the Accum leaked gas from the bottom.
