Guys,

Hope everyone is doing well and had a good start to 2014!

I have come across an issue this weekend with the fam's Cayenne S. Went to fill up and after that the car starts, runs perfect for 5-10 secs and then bogs down/shuts off.

What could this be? I am thinking fuel pump?

Any words of wisdom? Thanks in advance!!!!

Paul

 

Fuel pump failure is common for Cayennes. There are two fuel pumps. That might be a good thing to check first. When mine failed, my mechanic was able to test the pressure delivered by the primary fuel pump and determined that it was inconsistent.

 

Sounds like the primary fuel pump to me. Pull the fuse or unplug the pump and see if it will run on the secondary pump.

 

yup fuel pump..

 

+1...

 

So what's the verdict? You can't just leave brother's hanging.

 

pulled fuse #14.... car continued to run.

Soo.. primary fuel pump? where is that located.

Thanks,
Paul

 

anyone?

 

Under rear seat, this may help but search there is a DIY on the forum.

Should I be replacing both pumps?? some people are saying you should do both at the same time....

Thanks!

Change both pumps, also change the filter and regulator as well.

 

Could anyone please post some part numbers for this stuff?

Thanks
Paul

 

Specifically, you want part numbers for what year/model and components? Once you confirm, I will post with the corresponding part numbers.

 

We have most of the fuel components you looking for. If this for the 2004 S, Click Here for more information. Let us know if you need anything else or have any other questions.

 

2004 cayenne s... I need the fuel pumps/associated equipment to change out as my main pump failed.

Thanks!
Paul
