Hello,
I have an '86 Audi 4000S with the 1.8l/CIS-E engine. Recently it started losing power and about a couple of days later it got to the point where it would not keep running. It will start if it has been sitting for awhile, but then it dies. If I restart it, it will die again quicker, and then the third time it won't start at all unless it's been sitting again for a long time. I replaced both fuel filters, and the fuel pump seems to be running fine. I took out an injector and it is spraying some fuel when the engine is started, but I guess it's not enough. I have check all hoses going into the fuel distributor and can't seem to find a problem. I'm guessing it might be a fuel pump, but was wondering if anyone has had this problem in the past, or knows of a better way to make sure it's the fuel pump before forking over a lot for a new one. Any help would be appreciated!
Brian
