Jeep hard to start when the engine is cold?

I have a 94 Jeep Grand Cherokee. When the engine has sat for a while, it will barely turn over. This started about a week ago. After it has run for a few minutes, it will fire up like the battery is fully charged. If it sits for 10 minutes or 2 days, it starts as if the battery is dead. The battery is fairly new (about 3 months old). Any ideas as to what is wrong?|||Try charging the battery with and external charger, then starting it cold. If it works then your alternator is not charging the battery well - or your battery is not taking the charge (even on new battery).





I noticed that sometimes my trips are all so short the batteries never really recover (charge). So if I charge then using external charger, I can see it take about 1 hour or more to charge them. Then the cars usually starts much faster (like 1 second instead fo 5 seconds of cranking). Then it is good for another year or so.








Good Luck...|||what you have is a bad starter. What you need to do is pull it out and have it bench tested. There are auto parts stores that will bench test your starter for free or very little cost. What is going on is you have a very high resistance building up on the inside of the starter do to worn out parts inside the starter it's self. I feel that once your starter is tested this is what you'll find. While your at it make sure the battery clamps are nice and clean and that the ground connection between the battery and the ground connection on your engine is clean. This can sometimes cause problems also but usually not to the degree your talking about.|||Try to checkout this site http://www.cartechhome.com it has a lot information regarding car problem diagnosis.
