So on my 01 grand cherokee my pcu went bad so I went to a junk yard and pulled one for cheap . But now it just starts and runs for about 3 seconds then stalls .so my key doesn't send the proper signal to the used pcm ,and on every like 10 times I try to start it it will run and drive perfectly but when I shut it off it it starts and stall

IF YOU PULL OUT CAM SENSOR YOU HAVE TO PUT A TOOTH PICK IN THE TWO HOLES ON THE TOP AND THEN PUT IT BACK IN AND FACE IT TO THE BACK OF THE ENGINE.KING OF 4.0

Check the sensors on the throttle body. There is a sensor that controls air to fuel ratio. If that sensor is bad then the car will run and then stall out while in drive. I had the same problem when it was cold outside last winter. If you dont want to dish out the money without knowing if it is that part at fault or not then start the van pop the hood and located the throttle body. Place your hand on the sensors and give them a little shake and then make sure they are plugged in all the way. You could also turn the van off and unhook the sensor clean the connectors and plug it back in. That should do the trick and if it doesnt stall anymore then I would replace those sensors if I was you. One more thing. If your giving the sensors a tug while the car is running and you hear it going to stall you could located the gas pedal cable and give it a rev or two by hand so it doesnt stall out and turn off. By the way. You van isnt over heating at all is it?

after i replaced the battery in my 2003 350z, it would stall immediatly after i cranked it on unless i gave it a little gas. I fixed this by cleaning the MAF and throtle body valve. Total supply costs were $15 and took about 20 minutes. My Z is not only fixed but runs smoother and cleaner.
