mcnatprice replied to mcnatprice's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I found out how the check the pressure at the access point on the right (passenger) side of the engine under the A/C lines and got 5 lbs pressure when I turned on the fuel pump with the Durametric software. However, I can't seem to find anywhere that tells me what the pressure is supposed to be. 5 lbs. is lower than I expected, but have no clue if it is correct or not. Does anyone know where to find this info?
mcnatprice replied to mcnatprice's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I appreciate your quick reply. It's a bummer, I was really hoping I could troubleshoot this at home and not have to tow it again.
My wife was driving her C4 home from a 100 mile trip and it died about a mile from home (I know...thank goodness) She restarted it and it ran and drove for a few seconds, then died again. It started one more time only for an even shorter period and hasn't started since. I had it towed home thinking I would be able to figure it out. I got a Durametric tool and pulled the codes: P1130 - Porsche Code 361 O2 sensing adaptation, idle range bank 2 P1128 - Porsche Code 360 O2 sensing adaptation, idle range bank 1 P0455 - Porsche Code 94 - Tank vent system (this is an ongoing issue, replaced cap twice) P1124 - Porsche Code 167 - Fuel Pump Relay, below limit value Because the code 167 was fuel related, I thought this was the culprit and replaced the Relay. No love. I still get the code after the replacement. It seems as though I can hear the fuel pump working when I turn the key, could it be that the fuel pump itself is not working like it should? The car turns over fine, but will not fire. Any help would be appreciated...thanks.
