Hi everyone. This is a little long, but i figure I would include as much info as possible...Ted
i got sucked into helping my friend fix the fuel line on his 88 9000S. I am a vw person, and have/can do just about anything with them, but saabs are foreign to me.
the check valve on the sending side of the fuel pump was cracked where the hose attaches and was pissing gas all over the place. I get new check valve from Saab no problem, now the old plastic hose won't go on. get some hi-pressure rubber hose and snake it thru to the fitting in front of the tank (that sucked!), put hose clamps on both ends and yeeha, the thing fires right up. runs for 5 minutes then craps out. took an hour to figure out it was out of gas (DOH!).
get it running again, but it's idling roughly. turn idle stop screw up a 1/2 turn and it's better, but I shouldn't have to adjust a FI'ed idle...it's supposed to be handled by the FI system. drive the thing around last night for an hour and everything seems fine, idling a little high, but i can turn it back down later...
my friend calls me today and says that he can't get it to start. it cranks but won't catch. he thinks we're pinching the new rubber fuel line on top of the tank. I say no way, if it was pinched we couldn't have driven it around for an hour last night without it stalling. (i was flooring it last night around town just to make sure it wasn't pinched)
what should i be checking next?
fuel pump?
vacuum leak in FI system?
air filter?
My vw was having idle problems and i sprayed carb cleaner into the little unit that adjusts idle. Does the 9000 use some thing similar?
This is from JAn's VW page about it:

The other complaint I read on the forum was about wandering idle
after otherwise good running. The solution for this is courtesy of
a friend who went to VW's factory school.
The name escapes me, and it is called different names by
manuals and mechanics. What it is, is a check valve that is
in the "blow-by" or crank-case "breather" plumbing circuit.
On the 16v, this is a can about the size of a 12 oz soda can.
It is located at the end of the intake manifold above and
forward (towards the grill) of the distributor. It has two
rubber lines about 1/2" and 3/4" going to it, and a 2
conductor cable/connector going to it.
Apparently, this adjusts manifold pressure at low idle. My
friend tells me that VW use to replace this under warranty,
but it started to cost them big dollars. So, the procedure is
to remove it and flush it out with Gumount, STP or other
carburetor cleaners. Remove it from its bracket. Disconnect
the hoses and cable. Place it on the ground, and load it with
cleaner. I don't think you can hurt it.
The problem is that is gets sticky with blow-by oil mist and
doesn't open or close directly at idle.
