  1. Looking for suggestions. I replaced both fuel pumps of my 2005 Cayenne Turbo after the main pump died. Got it all connected back up and she runs great.... until it gets down to a bit under a quarter tank. Sometimes the engine just quits, other times the throttle gets intermittently rough, it shudders however, if I feather the gas lightly, it will continue to drive, if I press harder on the gas, it stalls. When I pull over and restart it, it drives fine for about a mile or so then same thing. Has anyone experienced this after replacing the fuel pumps? Is there an installation “gotcha” that I missed? Thanks in advance for all your expert opinions.
  2. Hi what causes fuel pump fuse to keep blowing FS 13 it is for right side fuel pump, I changed the fuse but its blowing again.
  3. Hi there, my cayenne won't drive as long i have the relay placed at 1/6 (the 404 relais) functioning. Once I take it out the car runs perfectly on one pump but once I put it back in the car stops working although I hear both fuel pumps working. What to do? Thanks for your response.
  4. First time post... hope to start contributing to the forum now! 09 GTS with 93k and excellent maintenance history, recently getting long cranking times and sometimes rough idle at startup. Starter is working properly so we can rule that out - not sure what to tackle first, coils? fuel pumps? HPFP? Durametric codes: 1023 Ignition Coil D Primary/Secondary circuit - upper limit value exceeded 1026 Fuel high pressure implausible - value below lower limit value The 1023 keeps coming back when cleared but never throws a CEL, the 1026 has been very intermittent but will throw a CEL. I swapped coils 3 and 4 (assuming D is coil 4 and coil 4 is rear-passenger side of engine?) and still get the 1023 code for "D" but no misfire codes. I tried pulling fuses 13 and 14, independently, and truck starts on both fuel pumps (with long crank). Logged with Durametric the fuel setpoint vs. actual pressure and I get 40bar at idle and it seems to keep up OK while driving up to 120bar at WOT. Plugs were changed at 80k but I believe to be on original coils and fuel pumps. So before I start throwing parts at this, any advice on what to troubleshoot next? Still fairly new to the Durametric so anythink I'm missing there with respect to data logging? Cheers, Eric
  5. Hello Porsche experts, I recently purchased a used 911 Carerra, 2003 and had the fuel pump fail. So I looked around in Orange County to find a Porsche mechanic and ended up taking it to Hergesheimer. They replaced the fuel pump but a few days latter I experienced something very troubling. The car would start but idle was somewhat rough. Revving the engine was a challenge in the lower RPM 1000-3000 then it became a bit smoother when driving with load on the engine in the 3000-4000 RPM range. Alarmed by this I called the shop to bring the car in, but this was the day before the Rennsport Reunion in Laguna Seca so I dropped by another mechanic who brought up these error codes on a generic diagnostics tool: P0134 Sensor Circuit No Activity Detected (Bank I Sensor 1) P0101 Mass Airflow Sensor / Circuit range issue Performance problem P0154 O2 Sensor no activity detected (Bank 2 post CAT ) P2098 Post Catalyst Fuel Trim System Too Lean Bank 2 P2096 O2 Sensor no activity detected Post Catalyst Fuel Trim System Too Lean (Bank 1) P0156 O2 sensor circuit malfunction (Bank 2 Sensor 2 post CAT) Initially I thought this was related to the fuel pump replacement. So I called the shop who did the work and they said bring it over. Their analysis identified similar codes and they suggested a few hours to review the harness and sensors in order to asses the problem. A week later i am still trying to resolve this and wondered if I should replace the O2 sensors myself. I have done brakes and other minor maintenance. What is the opinion of the forum here on next steps? I can provide further detail
  6. My left fuel (primary) pump went out on my 2004 Cayenne S, when I went to order the parts from www.sonnenporscheoemparts.com they said Porsche updated the fuel pumps and I would have to replace both because the old fittings will not fit to the new pumps. Is anyone aware of this update, have they installed a old fuel pump with a new one... or is it just best off to replace both at the same time anyway as if one goes out the other will be going soon also? Also I pulled fuse number 14 so I can drive with just the right fuel pump, does anyone know how long I can drive like this, parts wont come in for a few days. Thanks!
  7. Hi Everyone, So recently had a fuel pump go out on my C4. Conveniently way far from home. Got a local shop to repair, and they put the fuel pump in from the C2. The car runs, but doesn't feel quite right. Does anyone know the difference between the two pumps, apart from the part number of course? Wondering how far to push this.
  8. Hello !! I have a mystery I need help with. My car is a 2001 996 Turbo manual. I drove my car for 30 minutes, parked it and went on an appointment. Returned an hour later and...it would not start and ended up with a tow truck recovery. Well, having followed all the good advise on reasons and cures for non starting - my car still wont start !! New fuel pump relay, new fuel pump, new battery and new fuses. There is over half a tank of fuel and plenty of battery power. Itturns over really well but it will not fire !! Any other thoughts or potential reasons that I may have overlooked ?? best wishes Pete
  9. 2004 Cayenne Turbo Guys, I could use some advice. Cayenne has begun to leak fuel from the driver's side somewhere near the top of the tank. I can see small amounts of fuel running down the seams in the tank and you can smell fuel outside the car, but not inside. I can sometimes see a few drops on the ground after it's been parked. Related to this, I have a primary fuel pump failure, but these did not occur at the same time. The pump failed weeks ago so I pulled the fuse and have been using the secondary pump until I can get a clear window in my schedule to replace the pump. So now I am wondering if this leak is related to the pump failure or if I am looking at two different problems. Any advice would be appreciated before I start disassembling things. Thanks
