Question about 2007 Hyundai Tucson Limited
Our 2007 Hyundai Tuscson started up in a snap until around the 15,000 mile point. You would turn the key-- no gas pedal needed and it would start right up just with the quick turn of the key. Since around the 15,000 mile time, when you try to start it, the starter engages but it does not start right up. It may take 3-5 seconds of battery - starter activity, anong with pressing down on the gas pedal a few times. If you do not press the gas pedel it does not want to start-- the starter will just crank. The car does indeed start but not like it originally did. I am wandering why this is occuring? Could it be a computer issue or fuel injection issue? Any thoughts on this? I would like to shorten the battery-starter crank time as it seems excessive.

SOURCE: Car starting problem
I think your right that the humming is likely to be the fuel pump and so thats OK and should happen without the key being turned to the Start position. If the humming only happens when you turn the key to the start position rather than just when you turn the key to the point where the electrics come alive, then that would be a new symptom that would be interesting to hear.
I understand how frustrating this can be. Just a couple of concerns here. I think if your starter truely starts your car then there is not likely anything wrong with the starter motor itself. However that would not rule out a solenoid that is being problematic, and only activating occasionally.
I have had bad batteries classified as good by shops that check batteries, so don't assume that the battery is not the problem.
If we assume the battery and the starter are good including the solenoid then I would say you have to check all the connections on the wiring - i.e. take the terminal connections off the battery and clean then thouroughly - while the batter is disconnected take it out and trace the cable links to the Chassis earth connection and the positive connection down to the starter - take the cables off and clean the connections to the car, body and to the starter motor. Also clean the connection that goes to the Solenoid post on the Starter motor taht comes from the ignition switch ( the smaller connection on the starter) . Also check the earth strap between the engine block and the car body that allows the starter circuit to be completed. It could be a poor connection in any of these places is setting up a high resistance that is creating a problem for the starter circuit if the starter motor is physically not turning over.
Stick the battery back in - make sure all the connections are cleaned lightly greased and tightened and try to start it.
If it wont go - try getting a friend to help you put jumper leads across your battery from their car and trying to start your car. Make sure their car is running when you try to start your car. If it works every time 1st time with the jumper leads then I would have to suggest the battery on your car is bad - despite what the test guys say.
If it still plays up with the jumper leads after cleaning all the cables i would point to the Soleniod on the starter motor and suggest that the solenoid is defective.
If you want to check the starter directly - its a bit dangerous so you have to be really careful and have a very good friend who is willing to let you try this with his car battery and that would be while you get under the raised up car which is firmly choked and in neutral, with the starter motor in place connect the negative to the earth strap connector on the engine block, and then while the friend stands ready with the disconnected Positive jump lead and holding the negative jump lead in place on his battery, you climb under the your raised up car with the positive jump lead and a screw drive and attach the positive jump lead directly to the positive terminal of your starter motor while bridging between the positive terminal and the solenoid terminal with something like a screw driver or another think wire. (you have to be really careful doing this cause there are so many things to accidentally touch with the positive cable and cause arching ) but once your all in place your friend can attach the other end fo the positive jump lead to his battery and that way you have taken out all the circuitry and are effectively testing your starter while in place on your car and while under load. As long as your jump leads are good and you are in good contact with the starter connections and the soleniod contacts, if the starter doesn't turn the engine over you have something up with the starter. As you have taken every thing else out of the loop - i.e. the wiring and your battery.
If the starter does turn the engine over this way it says the starter is good and there are problems with the wiring or your battery.
Sorry for the long reply but thats all I can think of to try and work out where the problem may be.

Could be a problem with the clutch pedal switch. I'd have a look under the dash first to make sure no wires have been knocked of the pedal switch. If there's no sound, not even a clunking sound it may be the solenoid. I'd first want to eliminate the pedal wiring. Remove the small wire on the starter (most likely a spade type terminal) and using a piece of insulaated wire attach it to the starter where you removed the spade. Flick the other end of the wire on the positive of the battery. If the starter operates your looking at the pedal switch/ relay fault. If not its the starter. MAKE SURE CAR IS IN NEUTRAL BEFORE TRYING THIS. Ignition switched off. That way it will crank but not start.

Sounds like it might be either the fuel filter or the fuel pump, cause if you ran the tank down, you probably had sludge in the bottom of the tank that you sucked into the engine, you can try using a fuel system cleaner, you may have sucked sludge into the injectors running it, Zmax sells a fuel system cleaner, or there is one called RUN RIGHT, I would try putting some of that in letting it sit a few min then after it sat a few to soak in and break down the sludge, then start the car up, kick your idle up to around 1500 RPM do not go higher then that cause you will damage the engine, try that and see if that works for you, if not then I is probably the fuel pump or filter.
hope this helps.

Your gas tank must of been crushed,in some kind of offroad incident because if you can't fill it up the filler tube must be kinked.Or the pollution system is faulty such as the purge valve or vapor canister.
