Injector flood

Post by Ruff Ryder 6 »

I really hope someone can help me here. what i have is a V3.0 board with the MS-I daughterboard and plan to use MSnSE. it is a nissan 240sx with the KA24DE engine. my problem is that when i wired my injectors, for some reason there is 12v power going to all the injectors. i have a common power wire which goes to my fuse block and the each bank has 2 injectors on it (1,4 and 2,3). when i turned the key on my car the injectors filled my intake manifold with gas and there was well over a gallon of gas in the cylinders, plenum, and intake piping almost all the way back to my turbo. :shock: i checked my wiring and found that both sides of the wire has 12v power on it. i was under the assumption that MS would ground the injectors in order to fire them, so right now the injectors are just being held open. i don't really know what i have done wrong so any help would be appreciated

sorry to revive an old post. Were the injectors recently replaced? When a side feed leaks, it leaks into the intake usually, not externally. Check the o rings becasue you will flow fuel past them any time the pump is running.
