I just finished up installing a used rebuilt 4.0 L in my 2000 Wrangler. I used all my parts from the old motor to the new one, Intake, Alt, PS Pump, AC compressor etc... The motor turns over but will not fire. Pulled a plug and it smells like its getting fuel and there is fuel spitting out on the rail bleeder. Any Ideas on what I should do to trouble shoot this problem.
The FSM says something about if the camshaft sensor was removed the oil pump drive and sensor relationship would be lost, then it takes you through a series of steps to correct it, all the way down to using some DRB scan tool? Is this a possibility seeing as how I never messed with the crankshaft sensor. It says if the camshaft or crankshaft was rotated which Im guessing it was during the rebuild. Im affraid after all my hard work installing this I will have to rely on some crummy mechanic to help finish the job. Do you think thats possible? Thanks for the other info all of you.
Hey TD, I've got a lack of fire problem on my 98 and have been troubleshooting it as well. I have no fire. I've replaced the coil, crank sensor, and battery. Nothing yet and was thinking about checking the Cam sensor. Can you tell me where it's located?
