2003 Jeep Grand Cherokee WJ
So I I had my Jeep parked for a while do you blown rear so after a couple months I changed the rear and when I started it it stayed running for about 20 mins I had to jump start it because it’s ben long I guess but anyways the “lights were flickering and I noticed my radio would stay on when I had the key off and stuff so I was curious why it would be and still am” so I had a code “p1391 and the 6 misfire codes from 30-36 and it was misfiring bad” so I changed the “crank position sensor” as well as the “plugs” and “coil pack” and the “cam sensor” as well and now it still won’t start I changed the “fuel pump” as well and “filter” because I wasn’t getting gas to the fuel rail now it still won’t start it just cranks doesn’t even sound like it wants to start can someone please help I don’t know what else it could be “computer maybe?” Or even a “IOD fuse”? I don’t know if that wouldn’t let it start I don’t know it just stoped running out of no we’re after running like sh*t

 

You might get a little more help if you explain what year and model, and insert some punctuation.

 

Wrong forum. You have a GRAND Cherokee, not a Cherokee, and this is a technical question, not general chit-chat. Oddly enough, there is a section for GRAND Cherokee technical questions.

There are a lot of folks here willing to help you, but you have to do your part. Punctuation was invented for good reasons, and it's completely free.

 

Uh-oh. Not punctuation again.........

 

There are so many " " being used i thought i was watching Chris Farley as Bennet Brauer on SNL.

 

One thing I've found on WJs is a low battery will mess thing up really quickly. The computer doesn't like anything but a nice clean 12+ volts going to it's voltage supply. Anything less than 5 volts out screws up the programming and interferes with the bus system connecting all the modules together. After sitting for almost a year and being started on a jumper pack several times in that period, I had to get my PCM "reflashed" by a dealer.
