We have a 1998 V70 with a fuel pump fuse problem. Earlier this year, the car developed a problem where it would occasionally blow out the fuel pump fuse and refuse to start. At first, replacing the fuel pump fuse would fix the problem for a few months, but then the fuel pump fuse started blowing more and more often. (It seems to blow the moment you start the car - so, we replace the fuse, start it up and it runs fine, until you turn it off and have to start it up again! The fuse never blows while the car is running.)
Now the car is almost undriveable, it's so unreliable and goes through so many fuses. Sometimes we use two or three fuses just to get it going. We have taken it to two independent garages. The first could find nothing wrong and suggested we replace the 10 amp fuse with a 20 amp fuse (which we did, but it didn't seem like very good advice).
So we took it to a second garage, which also could find no mechanical problems, but they also checked the codes and said the car comes up with all kinds of weird codes that make no sense. The second garage suggests it's a software problem and that we take it to a Volvo dealer, because perhaps the software is causing the fuse to blow.
Anybody heard of anything like this happening before with a V70?
