Had to just take a break. I’ve downloaded the service manual and I’ve read both it an the pages you sent. I’m lost on what you mean by syncing the distributor and the map sensor. If I wasn’t bald I’d pull my hair out. Nelnocs dad.

The vacuum has been checked and moved between its port and another without changing the way the engine runs. The distributor was changed to correct shaft play Along with new plug wires.
Well Moses I just realized that my last message wasn’t sent. I have replaced everything but the speed sensor the intake air temp sensor which tests ok. The crankshaft position sensor. The only code it is or has been throwing is the vacuum on the map being unhooked to get the engine to run. With vacuum it is 10 degrees out of time and won’t start warm. with no vacuum it is at 0 degrees and starts and runs strong. We are going to check the wiring harness to see what it is doing. Just a rundown of parts replaced. Distributor, cam shaft sensor, coolant sensor, o2 sensor, map sensorX2, ECM, throttle position sensor, idle air motor,

Hello All,
i need your help. i have a 2.5L that I cannot make run with the MAP sensor plugged in. I have tested the MAP sensor and it reads good. i have tested the MAT, Engine Temp and Idle Air Control Motor as well. Replaced the TPS, O2 sensor and the ECU. i have checked for Vacuum leaks and have come up with nothing. it runs better with the MAP unplugged from vacuum. I am running out of ideas.
Any help would be greatly appreciated.

Guess there was a little difference in vocabulary. We did time the distributor when it was installed. Rotor is settings where the book calls for it to be. Tomorrow I will have a look at the speed sensor it’s the only one that hasn’t been checked out. Just wanted to update Moses as to the end result of the battle with my Jeep. I’ve continued to work on and drive but couldn’t correct the issue with the map sensor not allowing the engine to run properly. Fast forward to the first of may While driveing the jeep it just stopped would not start. Found no fuel at the injectors rail. Changed filter did not help. Pulled fuel pump and it wasn’t even still hooked up to fuel line the tubing had turned to jelly and the sock had disintegrated There was fibers smaller than hairs plugging the fuel pump. Replaced with new pump and sock. Runs like a top now. Never even thought about it starving for fuel. But it was. Again thanks to all who shared nelnocs dad.
