Engine Mechanical problem
1995 Ford Explorer 6 cyl Four Wheel Drive Automatic 160000 miles
----------------------------------------------------------------
Shut engine off after running fine, next time I went to start it the next day it cranked over well but does not fire.I checked the fuel shut off and replaced the coil. anything you can think of would be a great help.
I also put seafoam in the gas tank a week ago if that matters. engine runs very smooth and well with no problems. I know this could be a long list of things, your thoughts please
