Okay, Have a 2000 Cherokee with 125k. Bought it with 117k and 2 weeks starting having the No-start issue. Here is what I have done to solve this.
Replaced starter, replaced fuel pump and filters twice. When i dropped the tank the second time I scrubbed out the fuel tank to be sure. I'm kinda hittin the wall on ideas. I'm thinking fuel injectors? I don't know what else could cause this problems. Any ideas?

Ok, I am gonna try not to be a db, but I hate nothing more with people wasting there hard earned money on stuff that doesn't need replacing. We need tons more info, does it crank, or not? If it does crank does it have spark? If it does have spark does it have fuel? When it does crank does it Try to start, sputter, start then shut off, anything?

I bet the parts guy love to see you coming. You can't just throw parts at it. I replaced my fuel pump last week, after testing and finding the pressure regulator was bad. Than 3 days later I had a no start issue. All it ended up being was the rotor came apart. Do some investigating, it will pay off in the long run.

Yes the jeep cranks fine. Usually crank it once let it sit for a few seconds and try again and it fires right up. When I replaced the pump the first time everything was fine for a few weeks. I also replaced the plugs, i forgot about that.

hmm, can someone chime in? These have a internal regulator on the pump right? Sounds like it is taking a while for the fuel to prime. Maybe you should check fuel pressure? Check it a few times to c if changes. Might be a pinched line somewhere,

o, and I think it is commen for many, including myself with a 5.2, to have to crank for 2 seconds or so b4 it will fire.

Is there a specialty tool to check pressure? I assume I should check it at the rail. There is an outlet and when it has set for awhile nothing comes out of it when pressed.
