Thanks for the info, unfortunately this has been already tried with no luck.
How do I figure out which part is the problem? Any ideas?

Past experience here on BC would tend towards the crank sensor and most would find that the least expensive way to go, except that you won't since you can't do the work yourself.

You should wait and have Popatim help you with it. Plus then you'll not only learn, but will gain confidence to do more on your own.

Well, I picked her up last night. Only had the chance to drive her home, which was like 1 mile. Had to hurry to get somewhere and the Bonnie had no gas and the car seat was already in the truck, so I took the truck.
I'm driving the Bonnie to work today and probably go for a ride tongiht, so we'll see what she does.
She did ride fine coming home last night.
