I bought my daughter a 2000 Ford Mustang V-6 last summer, However sometimes when my daughter tries to start the car all it does is crank and wont start. When I get home and try to start it, it fires right up. The other day It stranded her at school and I had to go get her, once again the same problem cranks but wont start. This time it didn't start for me either, I towed it home and put it in the garage until the next morning when I would have a chance to look at it. What do you know it started right up, this is getting very fustrating to say the least. I don't won't to go and just start replacing parts, however my daughter doesn't is afraid to drive it now because she my get stranded again. Looking for help on what to do.

 

It could be a lot of different things. When was the last time it had a tune up and fuel filter change as well as the throttle body cleaned?

I had this issue with my mountaineer. It would not start, then it wood. I found that when it didnt start, if I hit the gas tank with my palm, it would fire right up. Changed the fuel pump and fixed the issue.

 

It could be loose wire connections to the starter as well I would check all wire connections sence that's the easiest thing to do then go from there any codes check engine light?
