Not starting,
I've done a bunch of searches and I'm sure there is one out there that answers my question, but because I haven't found a solution.
Changed the cam and swapped an lt-1 intake manifold onto the engine. Now I can't get it to start. I timed it while cranking, checked the compression, spark and fuel...all are there. Is there a tuning issue that I should look at? also I pressurized the intake...just a small leak on the top of the throttlebody, holds pressure fairly well besides that.
Any ideas, sensors computer issues I can look for.

Just some suggestions:
Try rotating engine till #1 is at top dead center. Take cap off and make sure rotor is pointing at #1 cylinder and wire.
Try static timing to begin with.
Do you have enough spark.
Injectors firing, nod night – starting fluid.

my next step was going to be pulling the cap to check the timing again. The fuel pressure and pulse is there, I pulled the rails and bumped the starter to confirm, good strong spray. If the timing is 180° (360° at crank) off would it shoot fire through the intake? that has been my experience in the past, but never been in that situation with fuel injection. I might try dragging it to life behind the jeep.
