I recently bought a 2000 sonata with the 4 cylinder engine and the car has 112xxx miles on it as of date. About 110xxx miles i tried to start the car and turned the ignition to the crank position but nothing would happen. I attempted this 3-4 times and then car turned over and was fine. Then, about 2 weeks ago it did the same thing, outside temp was in the 20's F, and i thought it was the battery so i jumped it and it turned over. Now, yesterday, the temp was about -20 F but the car turned over fine in the morning and when i tried again about 4 hours later it wouldnt crank over. The climate control fan would turn off when in crank position and i could hear a small "humm" but the engine wouldnt turn over. This time it lasted the whole day. I went out the next afternoon and tried it and it started right up. I have replaced the battery with a 825cca new battery and it didnt solve the problem. Could the starter be bad? I thought if a starter went bad it went bad, not that it would function intermittently. Anyways, any info would be greatly apprichiated. Thankx.

The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. As you have said you've replaced all the sensor, given quality parts most of what I see when this code happens is plugged passages within the variators themselves or the cylinder head. you might have some luck with a good engine flush and change oil change intervals to 2000 miles for a year.
Since the 4 cyl engine uses direct ignition, here is the info for the V6. Standing in front of the car, the cylinders in front are 2-4-6 and the cylinders next to the firewall are 1-3-5. The wires on the coil are 1-4-5-2-3-6. The actual firing order is 123456.
My rule of thumb for Timing belts: replace at 60,000 miles, and every 40,000 miles thereafter. Having said that, I often let cars go until the timing belt starts showing signs of wear (usually every 50K - 75K miles)
But www.autozone.com (register free at www.autozone.com) is recommending for your car driving in "severe driving conditions" (aka normal stop-start driving) that your 2000 Sonata have: 60,000 miles - replace 90,000 miles - inspect for wear 120,000 miles - replace 150,000 miles - inspect for wear
The 155 page owners manual (I found one at the link below - you may prefer to try Hyundai) makes no mention of the timing belt at all.
The sensor is located on the left hand rear side of the block (near the bell housing). It is held in place by a 10mm bolt. It's to the right of the exhaust manifold (LH - radiator side) on the V6. Once you purchase the new sensor you'll be able to identify it on the engine. The connector to this sensor is located in the illustration.
A word to the wise... replace the O2 snsr as well.
What's the difference between 'CRANKS" or 'TURN OVER'? Do you MEAN the engine cranks (turns over) but WONT start? If this is the problem, then there are NUMEROUS possible causes (i.e., fuel pressure (fuel pump) Bad Gas/Petrol, Ignition, Air Flow, Cylinder Compression, Crank Position Sensor, vacuum leaks, Nut behind the steering wheel, ECM, etc. An alternator belt would not cause the problem you describe. Take the vehicle back to the mechanic you replaced the belt and tell him to fix it!
OK!... Tell you STRAIGHT UP!.. this is a GUESSING GAME online. Fuel Pump failure 'apparent'?.. Did anyone VERIFY it was the fuel pump? Unless you guys know what you're doing, you need an EXPERT's EYE and BRAIN on this one -- it could be almost anything!.. Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there... otherwise it's a GUESSING GAME! There are too many possible causes which prevent a SPARK (i.e., fuse, ECM, Wiring, ignition failure sensor, bad CKP (crank position sensor), out of time, etc.
i would check the fuel injector o # 5 cyl... if the injector is leaking it will foul the plug out and cause a skip. the next time it happens remove the plug and check for wetness. you may also be able to put a fuel pressure tester on, if so install the tester, turn the key on 2 or 3 times leaving the key in the on position at the end, do not crank the engine, watch the tester for a minute or so and watch for a pressure drop.
A recent battery replacement might be a sign that the cables are not clean or tight after replacement if it was working fine before. The click is probably just a relay in the start/ignition system which is compleatly normal only you hear "it" now instead of the starter. check all the battery connections on each end and cables leading to the starter and make sure they are all secure and clean. -- LET US KNOW--
Has anybody been working on the car latley or has it gotten the spark plugs or wires changed latley the clicking that you hear is normally spark plug wires going bad they ark a spark to the closest metal around them 1 way you might be able to see is pop the hood and start the car at night if you see it sparking then thats it just buy a set of wires there prob 40 bucks... I had alittle toyota and thats all it was its because there small 4 cylinder cars so something tiny will make the whole motor act up,, Check that and let me know ill help you out more with any questions please rate me
