This happen to me like 4 days ago and the jeep been sitting in my drive way ever sens. But it started as this. When You get in a car and turn the key and it should start up right but my jeep wont start up. i have to wait 15 mins when i hear the relay clicking and i turn the key it startes right up and runs fine. But 2 nights and last night it started that way and it last 5 mins and it died. i try to kelp it running just give it little gas it work for a min and it died.
I put a new coil and i check all the wires next to do i find some broking wires and i fix them last night. i turn the locks so many times make sure the ararm is off. And I test the fuel pump and it work. But spake and fuel is not going to the right places the right time. i been reading about other people problems with those jeeps. i need help on this. that is my only car i have i hope i can get her running again. thanks

 

Are you sure the injectors are pulsing? If you pull a plug is it soaking wet?

It could be crank position sensor.

But it could also be a fuel pump. A fuel pump can pump fuel but still not be good. It may not be able to deliver enough to run the truck.

 

ya i know what you mean. But its not getting a spake when you try to start it up either. 4 days ago it did the same thing but it let me ride it to other state and back with noproblems but when i got back it wont want to start up and if it did it was only 5 to 10 mins thats all

 

A bad crank position senor wont give it no spake and no fuel?
