Anyone out there know anything about cars???

We've taken our 2000 Crapiac Shitfire...oops, I mean Pontiac Sunfire....to three garages now and almost $900 later (if you include all the cabs we have been taking) no one can seem to figure out what is wrong with it. It is a big mystery. We can put people on the moon, but three teams of trained mechanics and at least one diagnostic machine can't figure out what is wrong with one the world's most popular crappy cars.

First it started with the engine just quitting while driving. All the lights, blinkers, etc. stay on. When you try to start it again, it will eventually start, sometimes 2 tries later, sometimes 20 tries later. Then it progressed to just not starting up in the first place, till you keep trying over and over.

We had the battery boosted, battery & connections checked, engine electronics checked, oil/lube/filter done, topped up all the fuels/liquids, got a new air filter, new fuel pump (which was apparently a $600 shot in the dark), spark plugs checked, etc. And it worked great after we picked it up so we drove it everywhere. This was about a week ago. Until last night when we broke down on the coldest day of the year, in a black car at night out on the highway. It was fun, let me tell you.

We called the garage that put in the fuel pump and they really have no more ideas. When it quits the battery and engine lights comes on, but go away as soon as it starts again. When it quits and we try to start it, it kinda goes like duh duh duh duh duh. And if you are standing outside, you can kind of hear it wheeze a little after, before you give up and turn the key in the off position again. These sounds come from the passenger right side of the car in the front.

Anyone got any ideas at all??? Right now it is a two door lawn ornament and I am about ready to jump off a bridge. If only I could get to one...
