2009 CaymanS Fuel Pump Failures

Speed Addict · 09-23-2009, 12:57 PM

I got my 6spd CaymanS a little over 5 months ago, and I have already had the fuel pump burn out twice. Porsche can't find anything else wrong with the car, and they claim this isn't a widespread issue...something isn't adding up. Has anyone else had their fuel pump die?

09 cay 3k miles and about 4 mos. old...no issues

The first fuel pump failed at 4k miles, and the 2nd at 8k miles. So I guess every 4k miles I should just plan on having the car at the shop for several weeks. This isn't what I was expecting from a new Porsche.

Speed Addict,

Where are you located? What brand and type of fuel are you using?

Speed Addict · 09-24-2009, 02:13 PM

I am in San Diego and use 91 from Mobil/Cheveron/76.

How low do you run the fuel tank before filling up?

extanker · 09-24-2009, 03:07 PM

its not a good thing to run a tank low all the time [picking up dirt and running the pump hot] i think it would hurt pumps for the long life ,not a often as they are failing in his case...imo

This isn't the problem, I never let the tank get lower than a 1/4.

I hope this isn't the same problem that has been a huge issue in the turbo BMWs. They have been having High pressure fuel pump (HPFP) failures at a very high rate with many owners going through 3 or 4 in 20,000 miles. One wonders if Porsche is using the same supplier.
This seems to be the achilles heel of the direct injection systems which require very high pressure pumps (>3,500psi) to work. BMW has been blaming bad gas but that is clearly not the problem. Is there a way to find out if Porsche is using the same parts as BMW?

Speedaddict: there's always redress via the lemon law since you're in CA. Sorry to hear about it though.

FWIW, my wife has a BMW335i and the fuel pump just died at 3900 miles. If I have to deal with multiple failures, I'll send the car back to BMW. Repeat failures are simply unacceptable from ANY new car.

Just burned mine this weekend... 5,400 miles. Dropped off the car today, dealer promised to pick up tomorrow.

Yes, I have. Need help.

Jay240: the good news is that it sounds like your dealer has this part in stock. I had to wait close to 2 weeks each time my car went in for the fuel pump since this part was out of stock and had to come in from Germany.

ford_jj: have you taken your car to the dealer? How many miles are on your car?
