Will it try to start if you spray some carb cleaner in the throttle body? If so you need to check fuel pressure and if low, power to the fuel pump while cranking, the gauge not working could be a seperate issue. Could it be that the car is out of gas since the gauge doesn't work? Just asking. If so you may just need a sending unit. If you end up needing a fuel pump, you'll get a sender with it. I've never seen a sender and a pump go out at the exact same time, the use two different circuit's. The ECM really doesn't have any thing to do with the fuel gauge on this car.

good morning to you and welcome to fixya.com. hope we can get you fixed here. just a couple of questions first? have you changed the fuel pump yet? if so where did you buy the pump from? your pump is actually building up to much resistence and is unable to overcome it in turn no power is getting to pump as needed. i have a grand cherokee with 230k so i love hearing that you have that many miles. lets keep you rolling. let me know and ill help you out.

Seems to be a chronic problem with crank position sensors... On yours it is tested between b&c terminals and should have no continuity there. (should show an open circuit if good)
