I have a 2007 Murano S, with 134,000 miles. The engine was running fine until this morning. I passed a slow moving vehicle, and then immediately the car started sputtering and shaking. I was barely able to pull over before it died. I tried to start it, and it would start, but die a couple seconds later. I had to walk about a mile the rest of the way to work. This evening, I went to the car and tried it again, and it would run for longer, able to actually rev the engine and even move it a few feet before it died. I gave up for the night. Someone suggested a fuel filter, or perhaps a fuel pump. It does kinda feel like it's not getting enough gas to keep it running. It has a half a tank of gas in it. I read that the filter is part of the pump assembly. Any idea if it is the pump before I spend $150 for a new pump and change it beside the road tomorrow? And yes, I saw a video on how to take the lock ring off and back on without using the special Nissan tool. I don't have a fuel pressure gauge and didn't even see a place under the engine cover to hook one up, either. Thanks for any help.
