I had stopped for gas as I was running on empty. I hadn't driven it for a few weeks. The mpg have been slowly decreasing.I was at a red light and I spilled my drink, then noticed the radio went out and that the car was no longer running. There is a hole where my cigarette lighter should be but is not because of an attempt to fix it. Could it be my fuel filter got gunked up from sitting and being so low in gas or could it be that the drink got into my fuse box? what would it specifically be that would cause the car not to start? It sounded like it wanted to crank but it wouldn't.

the filter pipe has allen fiting can I unscrew it to remove filter without harming motor

My car won't start unless I hold the gas pedal to the floor.

Start it it smokes really bad an when it calling down it would cut off in traffic when I stop at a red light.

Have to pull door handle upwards HARD from the outside to open door. No problems opening door from inside. How can it be to fix myself? How much if shop fixes?

Next morning, car wouldn't start. The key turns, but it won't turn over. It's not making any sounds. The lights are not coming on, all electronic parts of car won't work. I don't know if it's the alternator or the battery. Any suggestions?

He says it will cost at least $80. Is it ok to do these myself if I buy the parts? Which parts? Where to buy? How difficult to do?
