I have a 1999 eclispe and having problems getting it to start. At first we thought it was the battery cause we junped it and it started so we changed the battery and it still does it. Then we changed the battery terminals cause we thought that might be it but still nothing.. I just don't know what it could be.. somebody help?

P0101 is the MAF (mass air flow) sensor that measure the amount of air entering the engine. Not enough air means rich running and a possible cause of fuel smell. Apart from running a little rougher there aren't always many signs that something is wrong.
P0107 is the MAP (manifold absolute pressure) sensor and responds to changes in manifold inlet pressure (vacuum). Problems cause include hard to start, long cranking times, sputtering/missing, blowing black smoke, poor fuel economy.

Take a good look at the alternator plug. The tabs on the inside should all look the same. Also a lot of corrosion can cause no contact. Replace the plug if necessary.

a little confusing here, maybe you need an ALTERNATOR, it keeps your battery charged, it you keep doing what your doing you will need a starter.

Dead Battery --Replace it

if you're sure the battery & connections are ok,check the starter motor and it's connections.if it does start without a jump, I would lean towards starter. the headlight isn't related. you need a new bulb. the filament inside is broken, when you tap it,you're just causing the filament to make contact temporarily

I'm guessing you checked the fuses already, so if you have spark at the plugs, look for a vacuum leak. If you still suspect the fuel pump, do a fuel pressure test.

I had the same problem couple months back and the problem was bad ground, once I got it corrected by cleaning out the battery terminal the car starts right up, thus I returned my starter back to the point of sale
possible you might have same issue

I am no expert and i am only 15 but if you go through a big puddle and it splashes on your engine spark plugs it is not good and if water goes into the exaust pipe
