This is my mother-in law's van and it's stuck in my driveway!!! I tried starting it and no success. Sprayed some starting fluid in the intake and van started but only ran a second or so. Rapped on the bottom of the fuel tank and actually got it started. Ran fine for a while in my driveway. Thought it was fixed shut it off to gather my wife and when I went to restart it it was the same as before. Tried everything that I did the first time to no avail. IT WOULD run with the starter fluid but that's it. Help me please
