Well traced the ground from the fuel pump to find out that the other end wasnt connected. Easy enough to fix. Now the fuel pump kicks in and I have fuel pressure but now there is no spark. All new wires, new plugs, cap and rotor were replaced also. I swapped the coil from my 2.5l engine with the 5.9l still no spark. Also tested the ASD relay it works fine. 20 amp fuse in that line is good also. Not sure what to do now. Any ideas?

I cant tell if the fuel pump is priming i dont hear anything. The crank postion sensor is hanging off right now so that might be an issue forgot about that cant seem to find exactly where it mounts but then again I only looked for a sec. and yeah the check engine light comes on at key start then goes off. All of the gauges work gas, voltage, oil pressure. I have pressed in the pressure releif valve on the fuel rail and it doesnt seemed to be pressurized.

what did you have done to the wiring harness? and are you talking about the engine harness from the 5.9 or the 2.5?
The 5.9l harness, the 2.5l harness and the wiring harness off of the firewall were combined together. -
Got the wiring harness and the PCM in the JEEP. Trying to start it and I cant get it to turn over. I dont think its getting fuel. Does anyone know if the 5.9L requires a higher fuel pressure than the 2.5L?

Anyone have any preferences as to how I would set up dual batteries? Any preferences on the wiring kits? Pros/cons Also wondering what is the difference between the red top, yellow top and blue top Optima batteries. I have a red top right now but its about two years old. I would think I should get two new batteries am I right in thinking that? I just got a mean green Dual battery tray. Thanks

Thats the plan waiting to get the wiring harness back was a little more involved that I had time for had to combine the old engine harness, the new engine harness, and the wiring off of the firewall. Also had the PCM flashed because the 5.9L had an automatic behind it originally and now I am using a manual.

I got an NV3550 hopefully it holds up.

I was trying to but when you in and start wrenching the camera is kind of out of site out of mind. All of those hoses were from the 2.5 not that there are any less with the 5.9L but it looks cleaner to me. Also you dont have to deal with combining three wiring harnesses which is a huge job in itself.

Well did you get everything installed? Any pics?
-
Is it running with the new engine? How about some pictures?Since you asked.
Hopefully by this weekend it will be running. Here are a few pics. -
I have an ax-5 for sale 98TJ. You guys would also need to change out the input gear to the transfer case. From a 21 spline to a 23 spline
-
When taking apart the transfer case make sure you get a good pair of snap ring pliers. The kind that are made for the angled snap rings.

I have a 2.5l out of a 98TJ
-
I want to say mine sits around 40.
(haven't driven it in a few days)

-
I have a throttle body from a 4.0 TJ if anyone wants it. Let me know
-
-
I also have 6.5 in my sound bar. just a little cutting was involved.
-
Not sure what year or model Jeep you have but my 98TJ did something similar to that and it was the catalytic converter. Should be easy to test if you just disconnect the exhaust before the cat. Could atleast rule out one thing.
-
So are you saying it would work with a 98TJ? Cause I have a four banger and would love to get a bigger engine.
