Wouldn’t start at all
My 1994 Ford Explorer started getting a little hard to start about a week ago sometimes. Usually after it has been running for awhile. It did not overheat. But this morning it wouldn’t start at all, it turns over good but acts like it’s out of gas, but it’s not. I let it sit a few hours and it started but then wouldn’t start again after I let it run a few minutes. It is getting air but don’t know about fuel or spark.
