First, I mis-understood previously and provided the wrong name for the part that they tried first, it's not a 'charge plate' for the spark plugs, it's a 'coil plate' that charges the spark plugs. (I think I got it right this time, I'm really not knowledgable about car parts.)

This morning the car still didn't start. They tried to order a part to fix it which, once replaced, allowed the car to start but then it shortly died out every time.

They also managed to kill my battery that I only have had since October during all the work, so they replaced it. They also told me that they have tried quite a few other things, and replacaed a few sensors and things, the car still will not stay running.

I plan to call them again in the morning to try another suggestion. Since the car was running absolutely fine, with no warning signs of ANYTHING and all suddenly it won't start and many things involving the fuel seem to be wrong, I wonder if someone put something in the gas tank or something? It was a Saturday and I was at the mall with lots of people. Maybe someone thought it was funny to put something in a gas tank? I will see if the mechanic checked my gas for foreign chemicals or if they can.

I feel like I will never see my little car again!
