    Recently swapped rb25 series 2 into my 95 240sx. The engine has great compression, is getting spark, and is building fuel pressure but I think the injectors aren't firing. It is side feed to top feed converted and has a forward facing intake manifold with fmic and z32 maf.

    Coils and spark is good. What am I looking for when checking the injectors?

    A buddy was telling me that it needs a tune to run properly with z32 maf, but shouldn't it start and idle with the maf unpluged? It's getting everything except injectors firing.
