no start after motor swap
I've been working on a new 94xj. I swapped my stroker motor from my 89xj into it. My 89 was a 5spd and the 94 is an auto. I swapped the auto flywheel in of course used the cps that was working before the swap. As far as I can tell all the connections are connected. I also used the distributor from the 94. Today I finally got all the loose ends tied up and tried to start. It would crank away but no spark.
When I pulled the motor did not mark the flywheel and torque converter so I'm not 100% sure if its in the right location. What am I missing?

First off, the flywheel only goes on one way.
You could have whacked the CPS upon engine install?
I would do these two things.
Setting Your 4.0 at #1 TDC
With #1 spark plug removed, turn the engine over clockwise using the 3/4" front crankshaft bolt. You will see the degree marks on your front cover. Mark the 0 with chalk or white-out.You will see the timing mark on the balancer. Mark it with chalk or white-out. While turning the engine over, put your finger/thumb over #1 spark plug hole. As the mark on the balancer approaches the marks on the front cover, if you are coming up on #1 TDC, pressure in the cylinder will push on your finger. If there's no pressure, you're at #6 TDC and need to crank the engine over until you see the marks coming together and you get pressure. Set the mark on the balancer to the 0 mark on the front cover.
