my ranger has almost 200,000 miles on it, and it runs pretty good. it starts right up with no issues 90% of the time. but after i drive into town or something(15 minutes give er take) and go into a store sometimes it won't start. it sounds like it'll fire for a split second and for some reason won't start. it turns over really strong like it wants to start, but it won't. then a few hours later it'll struggle but start, or it'll start like nothing was even wrong. after waiting about an hour one day, it still wouldn't start, but when i pinned the gas pedal it started?? it won't throw any codes or anything, and i have no idea what could be the issue. i've been told it's most likely a fuel related issue. any ideas of where to start? i replaced a cracked coil pack that i thought was the issue, but i still have the problem :/.
