I have a 1999 Jeep Grand Cherokee. It was knocking loudly, sounded like an empty spray paint can rattling on Jan 31st then suddenly just died. I have checked the pressure valve on the fuel rail and only a little squirt came out so there is obviously not enough fuel getting to the engine. So I went and purchased a couple cans of starting fluid and sprayed in directly into the throttle body while my fiance was cranking the motor over and still nothing. I pulled out one of the spark plugs and it was very dry and burned so I am guessing there is no spark as well. I don't know what to do here. What do you think it is?

Do below and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
