We finally got it running; it wasn’t the CKS but rather the timing mark on the balancer. We removed the balancer bolt to expose the crank keyway and discovered the pulley timing mark was at least 100 degrees off from where it is supposed to be. We went to the auto parts and measured the correct spacing, about 2.25” from keyway to timing mark, and created a new mark on the old balancer. We re-stabbed the distributor and it fired right up. Moses, thanks for your help. Mike

I just spoke to my friend after he reviewed my last post. He said it felt like the notches were closer together (not 20 degrees apart) like in the photo but the timing events were accurate. He also mentioned he thought the CKS wires looked a little damaged so he is ordering another one and we will see what happens when the new one gets installed. No need to reply to my last lengthy post.

Hi Moses, Sorry for the delay, I had to go home and my friend lives 4 hours from me. I’m relaying messages to him and he is trying to find time for diagnostics. We have verified the timing mark on the balancer is within an inch or so of TDC when the piston is on the compression stroke for #1. It’s hard to find exact TDC on #1 with the head on but we are close. I’m working on a theory the balancer mark is off on the front pulley, which would cause the distributor to be in the wrong place. I had my friend monitor the location of the pulse generating notches on the flywheel compared to

I just helped a friend install a rebuilt engine into his son’s 2000 Jeep TJ with a 4 cylinder 2.5L, manual trans and 4WD. He got the engine as a long block so we only had to reuse the tin covers, ignition and fuel systems. He got it from a reputable nationwide rebuilder so we are not concerned with dumb mistakes like timing chain installed incorrectly issues etc. We installed distributor as described in the service manual (TDC on 1 of compression stroke with 3/16 pin thru Camshaft Position Sensor and distributor housing etc.). The crankshaft position sensor is a two bolt type so no adjust
