Not running on left bank
So I finally got this engine in the car and ready to start last night. Get it running and its not running on the passenger side bank at all(1,2,3,4) they have spark and I swapped the plugs around(thought I may have gotten a bad box). When I pull the plugs out, they are dry, so I would say they arent getting any fuel. This is by far not my first engine install(2nd one in this car alone) but I'm kind of stumped.
anyone had this problem before?

RE: Not running on left bank
Did you run it at all before installing it in the car? Jut curious if it just happened during hte install or if it could have happened before but was never noticed because it was never started. If it's not getting any fuel on the entire bank, did you check the fuel rail and injectors to make sure something isn't screwed up? How is the fuel pressure on both sides? Normally I would go with a bad gasket, or cracked head (meaning no compression) but if it's not getting any fuel at all.....

RE: Not running on left bank
The schrader valve is on that side too, so that should make it relatively easy to see if fuel is getting to the rail properly. If it is, then may be worth it to check your injectors and make sure everything is hooked up properly. It's easy to overlook small things or seemingly simple things like that when working on larger projects.

RE: Not running on left bank
I did a compression check(failed to mention that before) I'm running the same fuel rail off the other motor, but the fuel injectors from this motor(updated 19#ers) I cant imagine that 4 injectors are bad and all on one bank, but anything is possible.

RE: Not running on left bank
I know, I wouldn't think all four would fail, that's why I was thinking either a connection problem (unlikely to forget to connect all four, but possible.) And I was thinking fuel starvation. That's why I figured you could hook a gauge up to the schrader valve and see what's going on there.
Or maybe it really is just a warped head, cracked head, or bad gasket.

If thats the case than a compression check would have shown it
And I did make sure the plugs were on the injectors. This has been driving me crazy since yesterday evening. I even dreamed about it last night haha

RE: Not running on left bank
What were your compression readings? Just curious. Im with sam on this one, its gotta be something with your fuel supply to that bank of cylinders, heres what Id try, no fancy tools required. Unbolt the fuel rail, pull the injectors out with the fuel rail (if at all possible), get yourself 4 plastic bottles, tape em to the injectors (so the fuel goes into the bottle and not all over the damn place), and crank er over, then youll be able to see if youre getting fuel.
