300zx, No start, will crank/partly fire

[Zynes]

So first off, hi i'm new to this forum or any 300zx forum for that matter. It all started when i got the car low price was AS IS, and i didn't care, anyway it was misfiring and i pegged it to a bad injector, the last coil pack on the passenger side plenum. We'll i finitely got around to replacing it and while i was at it i replaced the whole plenum as well because it was stripped and i was able to find about one for 20$ anyway i changed out the intake and injector etc now the car will crank and it fires every so often but doesn't turn over any advise would be great.
