No Power To Fuel Pump

Gen-2 997 High Pressure Fuel Pump Recall

I just received a phone call from my local OPC. Apparently, Porsche has issued a recall notice on some DFI 997s for warranty replacement of the high-pressure fuel pump. The official OPC line is Porsche is 'concerned' that the 'quality of the pumps wasn't up to scratch' on certain cars (mine included) and are therefore replacing them FOC. Symptoms are bad starting and rough running / reduced power.

But why, I'm asking myself, issue a recall if there's no issue other than rough running or difficulty starting the car? These could be dealt-with on an individual basis and let's face it, Porsche isn't given to issuing recalls (it let plenty of engines explode due to IMS bearing failure for example, but no recall). No - I think it must be more serious to spur Porsche into doing free 'repairs'. Call me cynical, but I'm wondering if the pumps are leaking fuel into the engine bay if they fail/start to fail. Hmmmm, just near all that hot exhaust plumbing!! That would certainly explain Porsche doing something about it.....

S80 Fuel Pump Relay Question

I made a simple jumper with a toggle switch to go across terminals 3 and 5 on the CEM (what would be the lower horizontal lugs on the relay) It's not switched with the key which is why I added the toggle switch, so the fuel pump isn't running with the car off. I can switch the fuel pump on and start the car, so I'm going to drive it to a shop about a mile away that has a system that's supposed to emulate the VIDA system and can replace the CEM code if needed. There's an XC70 recall involving CEM software that covers basically the same problem I'm having with the fuel pump not working because the CEM won't latch the relay. It's probably the same "feature" that's part of the Immobilizer, but caused by a software error. I'll be very happy if it's just software and I don't need a CEM. I'm 100% certain that my Volvo dealer would be replacing the V-V-T solenoid, ETM, MAV, fuel pump, etc. A very sad thing to have zero dealer confidence. I'll keep you posted. I took the car to my local indy shop that has an Autologic system and they were able to read all of the codes but unable to reprogram the CEM. There was an SRS code-00D3 that could be causing the problem. Very nice guys and no charge for this visit! So I bit the bullet and had the car towed to my Volvo dealership about 15 miles away. They called me and said my SRS computer under the console needs to be replaced for $1,100+. I had already checked it to make sure it wasn't flooded by coffee, or something, and the boot was intact and connector clean. I've seen Volvo SRS modules reprogrammed with Autologic on YouTube, so I'm going to bring the car home and check back with the other shop. When I picked the car up from the Volvo dealership, they had flashed the SRS module and plugged the relay back in, and the car is running fine. Total bill was $55.00. They warned me that they just fixed the symptom and probably not the problem. The SRS module was getting a signal that the car was in a crash and shut down the fuel pump. When I was working on the car, I found 4 or 5 partially empty bottles of water, sports drinks, etc. under the driver and passenger seats. (young adult driven car) Now I'm thinking that something may have spilled and gotten into an SRS wiring connector. For now, the car is tunning fine with no codes, and I have my jumper in the glove compartment, if needed. There will be no more bottles of liquid under the seats!
