Honestly, I've left mine on jackstands for hours. I don't see how anything can go wrong if it's stable. People wanted a failsafe, though lol

I'm also doing some reading on the PCM about the ASD relay? When I go back Iv'e read that maybe I can swap another relay into its place to check it? Any details on this?

Don't lay under a vehicle without jackstands. I also wouldn't leave one sitting for long on just a jack. You really don't need more than one stand per lifted wheel. If you lift the rear end, chock the front tires, and vice versa.

So if I turn the key to the on position (with out trying to start it) The Fuel Pump should be able to spurt some gas at the rail? and not just a drop?

I don't know it it's one cylinder or different cylinders at different times. I can't get it to "miss" when it's sitting still, only when I'm driving and that is making it most difficult.

So got my new all aluminum champion in and it gets to 240 every time I start it to get the thermostat open before I shut it off. I am sure there is still air in the system as I have not replaced all of the coolant I drained. I filled the radiator as much as possible, started the Jeep and pressure builds almost immediately and starts overflowing out of the filler, I thought it was supposed to go down? It did every other time I changed the coolant. I also bypassed my heater core (no blower, no AC), could this be causing me any problems?

Still creeping after burping it some more, again almost immediately the pressure builds and starts over flowing, I am only able to add like a cup of water each time I let it cool and fill some more.
