it 4.0 and it has gas.
I did get spark.
took out the injectors and had my wife turn the engine over and fuel came out the injectors.
And yes it was running before.
Also change the cam sensor
This was a rebuild motor and the engine compression check out fine.
But every time i try to start it sound like its back firing. But then sometimes it will catch a run for a few seconds and then shut off.
I 've been working on this Jeep on and off since November of last year and I really need to finish it before the summer is over.
The only thing I have not change is the crank sensor on the flywheel.
