I've got a 97 Ski Nautique with GT-40, fuel injected. About 1 year ago I had some electrical and fuel issues and thanks to the posts on this site was able to track the problem down to the 2 relays on the back of the engine, specifically the one that controls the fuel pumps. I replaced both of them with genuine parts (from skidim) and have not had a problem until last week. The engine died for about half a second while at speed and then picked back up again, and on 3 or 4 other occasions would crank but not start. Doing some tests it looks like the relays are again at fault.
Having been through this issue before, the symptoms pointed to the relays and they are very inexpensive and easy to replace. But the question raised is why these relays are failing again after only 1 year in service. I suppose it is possible that one of them was simply a dud, but I'm wondering if anyone else has had ongoing problems with these relays failing. As they are only relays, I would think they should last for several years without a problem. Perhaps they don't have as long a life span due to the hot and dry climate I live in (Sydney Australia), but then this isn't that much hotter than a typical summer day in California either. I don't winterize here as the temp does not go below freezing.
Could this be a symptom of an overall wiring problem due to the age of the majority of the electrical wires?
It's no problem to keep a couple spare relays around, I just hope this isn't a symptom of some other more serious electrical issue.
Would appreciate any feedback.
