First off id like to thank everyone that makes Nico great. thanks to the handy search button, i havnt had to ask a question about doing my swap untill now.My problem is, after all this time, ive finaly finished all the mechanical work on my swap, i started the sr20, and it fired an the first go, and settled into idle like nothing, it sounds great and seemed to be running realy well. i took it for its first test drive at midnight on sunday, went to the gas station. Drove like a dream. So i park and fill up the tank thinking "finaly, i can die happy lol"

I get back in and try to start the car. nothing happens. i can hear the fuel pump kick on, but the starter isnt working. Earlyer that weekend, i had the same problem, i used my fsm to trace the problem to the starter (EGI) relay. I replaced the relay with another one i had out of my parts car. I found that i had blown my 100A fuse in the trunk (battery relocation) and replaced that also. The car fired right up. I drove home from the gas station and the car ran well. The next day, i tried to fire up the car and again, nothing happened exept for hearing the fule pump again. After some more searching, i found the same problem, blown 100A fuse, blown relay. i replace the relay again (parts car) and bypassed the fuse this time. The car started, i drove, came home, turned the car off. the next day, i tried to start the car again, and again, the relay is blown. I have no idea why my car eats relays. anyone have any ideas?

ive already checked all my grounds and they are good. ive checked all the wiring again and again, but cant seem to find anything "bad" but perhaps im just not looking for the right thing. i dont think im getting a short anywhere. can you think of anything else that would blow relays. (and please dont say my mom lol) lame.

the home made variety, but i didnt skimp. im running 4g wire up front to a distrabution block and from there to the starter and accesories. in back im grounded to the spare tire tower, ive heard this can cause problems, but ive ground off the paint and im getting a perfect ground. ive tested everything with a multimeter.
