| :Which lower manifold am i supposed to be running the rails and injectors on newer or older style plenum? 1990-1993 lower plenum :I know its possible to run on both with the exception of the newer style plenum to run without the rubber insulators. I have both lower plenums available and decided to use the older style plenum + new Nissan insolators BUT my #2 cylinder isn't/ hasn't been firing since my Z's first startup after the rebuild. I've checked literally EVERYTHING and am kinda stumped. Its got spark, fuel (good readings with the multimeter) and a compression test resulted in 156psi. Possible vacuum leak due to the rails not fitting properly? Almost ready to go jump in front of a speeding truck >:( move the coil packs around. move the plugs around. move the injectors around. see if the problem moves with them.
