NEED HELP on 97 Jeep Gr. Cherokee

[craiger]

Hello. I am having a problem with my 97 Jeep Grand Cherokee Laredo. It has a straight 6 cylinder motor, AT tranny. It will start for 2-3 seconds then dies. If I rev it up it will die, if I let it idle it will die.

Now here is the good, I have another identical Jeep Gr. Cherokee that I have switched many parts already on and off of it to check out what the hell is going on. So far no luck. Here is what I have switched: Computer, Coil, Pick up module, MAP Sensor. The running Jeep still works when I have taken these parts off of the non-running Jeep. So I know that these parts are not the problem .

I initially thought it was a fuel problem but it is reading 50 psi at the fuel rail line.

Please Help me out here.
