I checked their is No spark at Plugs
No pulse at injectors and only fuel in rail
after the key is turned off.

Re: 02 jeep no start Sign In
Are you getting fuel pressure prime for 2 seconds when the key is first turned on but lose it when cranking?

Re: 02 jeep no start Sign In
Yes
In normal older engines I would replace the Module
I was a mechanic for many years but they have changed a lot in
10 or so years.

Re: 02 jeep no start Sign In
This car doesn't even have an ignition module and if it did, it would have nothing to do with injector pulse. It should be tested first but your probably looking at a bad Crank Sensor.
