Started, but now it won't(yes I searched)

ok So I am doing a swap of the RB20 into a 93 S13, we had it running but now it refuses to start, it will turn over but won't fire, I checked the wiring the only thing that I found odd was "the orange wire" I wired it into the orage wire on both the RB plug and the underdash plug. but when I traced it out of the firewall it ended at what appears to be ,well looks like the plug for the wiper motor. any ideas where this might plug in or did I do it wrong?

maybe the fuel pump isn't turing on with the key? did you check for spark? can you hear the pump prime? might help a little.

yeah check for spark and fuel, also are you using a brand new battery or has it been sitting for a while?

did it start and run good, or did it start and barely run...check all your plugs. they can look fully pluged in, but not be plugged in at all.

My car started, but was running on two cylinders, then the next day, would crank but not start..

I spent about 8 hours screwing with it and finall found a loose cas plug..
