Alright here is my 2 cents worth. I have been using this site for 3 years and it is very informative but I almost never comment. I have a 77 280z 2+2 that I have turned into a race car. I have the fuel injection and on 2 different occasions I have fried the relay you are talking about. Both times while racing, the first time I was lucky and had a spare but the last time I had no spare and no way to get one in time for the race. I made a lot of inquiries and was able to rewire the car to finish racing the weekend. The first thing I was able to do was to direct wire the fuel pump to a on/off switch. the next thing was to jumper the wires that went into the relay. Now when I say I was I mean an engineer on my team did it. I have the diagram he made on how to jumper it so I could tell you if you want to go that route. But I am still trying to figure out some of the bugs with it. The first bug is all my gauges do not work, which really sux for racing and I do not seem to be getting full power to the injectors. I can race just not as fast as before. So to sum it up it can be rewired I just haven't figured it all out yet.
