My 2003 elantra GLS does not start after been sitting for a few months.
Usually engine makes cranking noises for a few seconds when the key is turned to ignite and it starts when I release the key to "on" position. But this time, it continues to crank as long as I hold the key at ignite, yet goes silent and dead when I release the key. It seems to me that the engine is trying to start since it trembles very bad and the belt under the hood runs. It just somehow does not start up.
The battery is just replaced new and should be no problem. All other electrical parts work fine. Any suggestions? Thanks a lot!

disconnect the earth wire from the battery and place a multi meter in the circuit and read the current draw through the current (AMPs) section of the meter. That will tell you what is drawing current and how much.. Things to check include the glove box light is off, boot light is off. the radio amp is off when the ignition is off. When you have done that hook the multimeter across the battery after replacing the earth wire ( red lead to positive and black lead to negative) and start the engine hold RPM at around 1200 and read the voltage in the battery It should be 14.5 volts dc now set the multimeter to read ac and see if you have any voltage there IT should be 0 voltage . That will show that the alternator and rectifier diodes are ok. Check that the drive belt is in good condition and tensioned right.. You say 3 batteries in 13 months . How many have been brand new out of the battery shop type and how many are new to you from some place else. If they have not been new as off the shelf new then have a load test done on the battery as it may have an internal short
it can if you have the proper tools and a little patience its not very hard at all it may be a little snug i cant remember off hand where the starter is located on that car but its relatively an easy fix.
If you follow your upper radiator hose back to where it attaches to the engine, that is where the thermostat is located. it is called the thermostat housing and it is held onto the engine with 2 or 3 bolts. If you purchase the thermostat from an auto parts store, they often can give you some specific guidance too. Of course, you need to start this project with the engine cold, and first drain the coolant out of the system. Make sure you have a new gasket or sealant to install teh new thermostat too.
If the car is turning over but won't stay running, it is not the ignition switch. You also said it is "trembling very badly" when it is turning over, this leads me to believe that it might just be moisture under the distributor cap or a bit of carbon build up on the rotor.
Try this: remove the distributor cap WITHOUT REMOVING ANY OF THE WIRES. There are 2 screws that hold it in place, loosen them and turn the cap over to look inside - if you see any moisture, wipe it out with a dry rag. Next inspect the rotor, that's the piece still on the engine under the cap, on the end of it is a metal contact. If it is at all blackened (carbon build up) either LIGHTLY scrape it with a flat blade screwdriver or LIGHTLY sand it until shiny with fine grit sandpaper. Put the cap back on, retighten the screws to secure it, and see if that gets it to start.
what u do is go to your local auto supply store and buy throttlebody cleaner you remove the rubber hose from the throttle body with the engine off of course u open the throttle and spray cleaner in it then use a tooth brush inside it replace the hose done
except it will be hard to start the first time crank engine over with foot to the floor on the gas pedal do not pump it
