The fuel accumulator is an often overlooked component, but it can be changed without draining the fuel tank.

If you want the details including a simple on-the-car test and a FA destructive failure analysis, search for thread started by me, Duke2.6. There aren't many.

You can use a vacuum pump to determine if the removed FA is actually defective.

If you can ultimately find the cause of the problem and what caused it to be fixed, let us know. These cars are fairly complicated and sometimes problems can be solved, but we don't know what the actual solution was.

Let is know!
