[QUOTE="jeepy0706, post: 436462, member: 20679"] Hello, I did look and see if this was a topic already and I did not see what I was building exactly, so here we go. I am building a stroker motor from a 4.2l block, with 4.0 pistons and crank. I used the 52 coded head off of a 4.0hp with all the wiring so I could convert it to fuel injection. I then got a cam from a build I did a few years back it is a 242 crane cam. so, I have all that together and the motor spins great and has great compression. My jeep was the 2.5 so I cut the motor mounts and moved them so I could install the motor. It is in an bolted down fitting good with a 96 grand Cherokee automatic transmission with the wiring harness. I have power to everything and all seems to be working, so your wondering by now what my issue is. well , here it is. I used the fly wheel from a manual trans that fit and bolted on to the auto. The crank sensor is for a auto trans. I think this is where my issue is and why its not cranking up. also I am having trouble mating the 95 wiring harness to the 96 harness so that I can use the 95 dash gauges and the 95 column.
