Grand Cherokee won't start
Hi, I have a 2000 Grand Cherokee and about 2 weeks ago I noticed a problem. My jeep started up no problem when i went to work in the morning, but then after i got off and went to start it, the engine just cranks and cranks, but will not fire! I had a co-worker drive me home after trying for so long. Then I got to work the next morning, turned the key and it started right up. Since then it has happened 3 times and is totally unpredictable. Any suggestions would be great!! Thanks!!!
