voltage alone? My friend has a Volvo that has been known to have ABS modules go bad b/c of cracked solder joints and they were not exposed to any fuel or moisture(gel coating)...we had to melt existing joints and add more solder to correct the problem. Perhaps Nissan just used the wrong grade of solder for the amount of heat the injectors are exposed to under the hood. I thought I heard something about solder crystallizing..maybe that's what happened here.
