If it is flooding then the fuel pump, module and injectors are fine. :confused: ok the module could be holding the injector open to long.


Just a quick check, Brad. That's all. Sure, the car was running rich before so I am doubting as much as you are that there is a fuel delivery issue. That said, things may have changed since the car is not running at all. Also, Ben says that he can't hear the pump running so following these steps are the only way to confirm. I'm 99% sure that the pump is working based on the symptoms we've been told. I'd rather be 100%. Again, it only takes a minute or two.

and then after it is pressured up only run again while cranking or am I wrong again.

I have not worked on mine yet but I thought that was the way they were built, so that in a accident, when the engine quit, the pump quit, or is this only an american safety feature.


The 928 fuel pump isn't energized until the starter circuit is opened. The pump continues to run for a couple of seconds after you shut the car off. Opposite of an American car.

Pull the fuel pump relay, bridge pins 30 & 87 and listen to the pump, you will know right away if it is working. This is also the way you want to test for fuel flow.

Ben, if you follow this tip then be VERY CAREFUL that you are bridging across the correct terminals. Doing it incorrectly could damage the computer.

Hey guys, Thanks again for the help. I do have manuals downloaded and I will try the test with the jumper. Sorry for not being more involved. Been pretty busy here. Will get answers soon. Thanks

Don't sweat it, get it done on your own time and don't rush it. Sometimes something that should be easy takes hours, and sometimes it goes fast. Doing it properly is the best thing.

And that is so true and the best advice out there.
