This is a good one. I have a 95 XJ, 2 door, 5 speed, 4.0. After 280,000 miles the motor finally gives up. I decide it is time for a new engine. I buy one and pull the old one out with the wiring harness still in tact but unplugged. I pull all of the wiring off of the old engine and all of the amenities. ie oil sending unit distributor and coil and so on. I put all of this on the new engine. I put the engine back in and plug everything back in. I go to try to start it and nothing. I check all of the wiring, it is all good. I can get the engine to turn over if I hook a wire from the batery to the solenoid to jump it. The fuel pump will not run because it starts off of the starter relay. I am trying to go thru the wiring diagram but the haynes book is real vague and I don't have a yellow and brown wire into or out of the ECM. Any ideas, I am out.
