03 Explorer starting issues

My dads 2003 Ford Explorer doesn't like to start when it's cold to the point where when it's supposed to get under 40 he rents a car. He's taken it to the dealer and they didn't find anything. Could it be a problem with the starter? If not, any ideas?

Did he leave it overnight for them to experience it? Does it crank and not start or not crank fast enough?

He could take it to dealership and leave it overnight out in the cold for them to try and replicate the cold start problem .

Re: 03 Explorer starting issues

If the battery is original since 2003, chances are good its toast. When a battery begins to freeze the electrolyte is limited on performance, especially if the electrolyte in the battery is low. If it's not too low you can add a softwater and vinegar solution (50/50mix) to the battery. If the level is very low and 250mL isn't enough to bring it up, then get a new battery. If you're unsure how to check or add solution to the battery, don't. The coil may also be on its way out.

If he wants to leave it at the dealer or a reputable shop. I'd start with the electrical test, move on to fuel pressure test next and knowingly it's one of those. If it has 75K or more miles and hasn't had a tune up, get it.
