To begin with I'll give you a little background on the swap to let everybody know why exactly I have decided for the swap. I have a '99 Si and my brother has a '97 DX. We both have planned on modifying our vehicles but quickly decided to focus all of our efforts on a single vehicle to save money. Given my brothers hatch is already gutted and cage-ready, minor suspension work, etc etc, we decided that we are better off by putting the b-series motor into the hatch and his Y7 into my car. I thought from day 1 that this would be a straight up swap and I'd be back to driving my car in no time. I've swapped axles, main engine harness, ecu, radiator, pretty much everything for an engine swap to work. I am now to the point where I can drive it. Everything is buttoned up and ready to go, however the car will not start. I'm getting spark, the starter is turning to motor and everything is working....except I'm not getting any fuel. The fuel pump/main relay is not clicking like it should be when you turn the key and my pump is not turning on to prime the lines. We checked the pump, check the relay, checked the fuses, checked everything and for the life of me I cannot figure out why the relay is not working. The ONLY other thing that I can think of that would be different between the two cars would be the interior/dash harness. Would there be a difference in the harness to where it would not let the relay work?? Or is it something smaller than that? I'm really hoping that it may be something stupid that I have overlooked but any help is much appreciated thanks.
