What would prevent the injectors from firing? I have 35psi on the rail in the on position and it jumps to 40psi when i try to start. I just put a crankshaft position sensor and a camshaft position sensor, along with all the other tune up. I have spark on the coil wire at the distributor also. I dont know what else to check. And it dont fire with starting fluid

If vehicle does not start for a few seconds after spraying with starter fluid you are not getting spark. Is check engine light on ?
What is a good fuel pressure for a Jeep Grand Cherokee 5.2 liter v8? The Jeep runs butvat times when I go to park it it shut off then will start right up but dies again. Did it a few times last week when I was parking it at work . Then yesterday when I got home going up my driveway it stalled Again
Your fuel filter may be cutting the needed pressure or the pump in the tank is going out, they're quite notorious for this. Replace it with an in-line pump (place it after the filter), even better get a mechanical pump which bolts at front, bottom of the block & is driven by the camshaft. Very easy to install and a lot less$. Any parts store can help set you up with all that's needed.
