went out today to do my daily start up, and the car wouldn't start! the battery is good, the car will turn over, but won't start, it did go a while without gas due to lack of $$$ about a week! and now it won't start! i turned the key over to llet the fuel pump do its job and i herd it, so idk what it could be? do any of you know what it might be? by the way it's a sohc ka.

could be a number of things. could be the alternator bad or going bad. Could be the starter going bad. Could be the clutch start solenoid. Maybe the plugs. No gas or low gas could be a fuel filter problem sucking up all the junk in your tank while low. Check those things. Try banging on the starter with a screwdriver lightly then starting it. If not replace the fuel filter and check your plugs.
thank you im on it!
update/ so i tried everything stealthe said and the plugs should be fine, the alternator was already bad, the filter is fine, still got presure from the fuel pump, tried tapping the starter and nothing worked, so does anyone have any more ideas?
hmm the engine is turning but not starting...only thing I can think of are the plugs(not getting spark),the starter is bad. Could be a number of things. Frickin cars take so much just to start them. One little thing off and your screwed. Good luck man.
by the way,you said the alternator was already bad?..is it bad now?...becuase that would be the problem.

He said the car cranks fine. It would atlleast turn-over with a bad alternator just wouldnt stay running.

ground out plugs to see if you have spark, you may have a bad coil. Or a clogged fuel filter. My two cents...

i have had the bad alt for some time now and it still ran.

i already checked the filter and its good, so i will try the plugs and see what happens, any one else have an idea?
update/ so i checked the spark plugs and there all giving spark! what else could it be?
how did you check the filter?..I'm curious. Those things are very precise..one bit of particles or sediment clogging it can throw it off by not letting enough fuel in to start your motor. I would change it for the heck of it..they are only $10. My last car had a bad alternator and it wouldnt start after a while because the battery finally went dead from it not being charged by the alternator. Are you getting any power at all?..interior lights,radio,etc?

when you pulled the plugs, did you see if they were wet with gas at all? crank the car over a few times and then pull the spark plugs. Look to see if they have fuel on them at all. Similar situation happened with my car.

Turned out too much fuel was coming into the cylinders and the car couldn't fire.

Also, another thing you could try is crank the car over a few times. Then, unplug the fuel injectors and see if the car fires. It should only be for a second or so if that is the case.

the way i checked the filter was i just dis connected the hose above it with the pump on and before i have done that and the pressure was the same. about the lights and everything they light up great, i always recharge the battery so the alt is no prob.

actually, yes there was fuel on the plugs. and i know it has too much fuel to air mixture, how would i be able to slow down the amount of fuel going in?
you can do a pressure test of the fuel pressure regulator, see if thats working as it should.

However in my case, as weird as it sounds, my ignition switch went bad. If i try starting the car with the key, it won't work. It will just flood the cylinders and won't start.

Try this.

Unplug the connector that goes to the starter solenoid. Take an insulated wire and touch one side to the connector coming out of the starter and then touch the other to the positive terminal on the battery. See if the car starts when you do that. I did this for mine and it works.

If it does, your ignition switch is bad.
