Engine is not running?

Hi thank you for your response as I was trying to figure out how to reset the security system I found a shorted fuse in engine compartment. Sensor (3) 15 amp.I am able to start the car but shut it down because of a loud tapping sound. Can't tell if it's coming from cylinder head or pistons but it don't sound good at all. As far as I can tell the sound is closest to cylinder #1 or #3. Have the following codes each is listed twice PO223, P2106 and PO365. It never made any tapping sound before and it's so loud I shut the engine down. This model has two camshaft sensors exhaust and intake. The throttle position sensor or throttle control actuator?

Wow Thank You Very Much I will check throttle body and clean. I will have the timing looked at along with camshaft and intake/exhaust valves.
Thanks

Update. I cleaned the throttle body and had a mechanic look at the car. We retested compression cold start and 160 on all four cylinders since replacing blown fuse. Mechanic suspects the variable valve timing could be causing the noise racket and suggested replacing the VVT Solenoid or Hyundai calls it a actuator. I'm going to test the one on intake side for resistance. If out of range I will go ahead and replace it. I can only pray that the timing didn't get messed up and have to realign everything and valve adjustment. Pulled valve cover off and looked at one V.V.T solenoid/actuator. It had some gunk but not bad. Screens looked good. Tested Camshaft sensor bank 1 and 2 voltage from computer. Close to 12 V but battery is getting low again right at 12 volts 11.95. Is it possible to test camshaft sensor T.P.S sensor/actuator with ignition on engine not running? Was able to identify Pin # And wire color for both. Please help

I have some good news the super loud type writing noise stopped for now. I slowly pulled out of drive way to feel the noise vibration. My guts wee dragging on the road behind me but after going around the block they caught up. Went ahead and bought oil control valve solenoid or Engine Variable Valve Solenoid exhaust side. And was down to two codes po223 and p2106 after I worked on ETC actuator. And Throttle position sensor and installed the part. Now have codes 223 2106 365 2110 and 2119. Test the power to T P S #1 and #2 Have 4.0 5.0 volts and good signal too. I would greatly appreciate your help with correcting the no start from hell.

Hey thank you for your time in helping us with the Santa Fe. We suspected it might be the Engine Control Module. All these codes. It has troubled from us from the first day when these intermittent no starts began there was no warning no Mil light, It came on only after replacing the battery. I had a mechanic look at it too. He also suspected the computer. I'm taking it back to the dealer tonight.

Hi I have no clue as to how and why but when it began our Santa Fe was running fine and showed no signs of trouble. What would cause intermittent no starts/no crank, replace battery, no start/no crank now with a check engine mil. We take it to Hyundai Service dept who tells me they could not properly diagnose the no start with engine not running, perform compression/leak down tests with active codes 223 445 2106. Tow the car home find a blown fuse related to one set of codes P0445. I'm able to start the engine but have a loud tapping noise. Recheck compression and have 160 psi on all four. Test drive the car noise goes away after driving 1 mile up to 65 mph. Park it have two codes 223 and 2106. Next day start engine have hesitation in engine power and idle and a total of 11 codes. With the addition of the two codes mentioned my code reader showed 2009, 2110, 2119, and 365 twice. P2110 is also a code listed in a 2010 Hyundai Santa Fe 2.4 T.S.B that pertains to the ETC relearning set values. Take it back to dealer. Now we have active codes P0200A, P0222, P2106 and the Hyundai mechanic tells me they will need to replace the intake manifold and ETC body. How all of this came about but it's confusing to me why the check engine light did not come on from the moment the intermittent no start began? Old battery had good voltage at cold start and alternator was charging. The starter wasn't acting up either. The blown relay fuse was a sensor fuse for Injectors #1 - #4, canister close valve, canister purge control solenoid valve, oil control valve 1/2 exhaust/intake and variable intake manifold valve #1/2 The 5 year 60 warranty has expired and we are the 3rd owners the only warranty that still applies to the car is the 8/80 federal that only covers PCM, Catalaytic converter and 0BD2 device. The California emissions 7/70 does not apply because car has 71.000. My question to you sir is this WTF happened here? Is it possible to consider a computer malfunction because if there was a mechanical problem with air intake or the E T C why didn't ECM/PCM pick up on this?

Once my car was not able to start due to winter cold and may be oil got freezes as per the Hyundai technician. He tried to start many times but failed it cranks over and over but doesn't run?

The guide helped me find out my fuel pump went out, thanks for he help this site rocks!

I have another question about my other vehicle. Its a 2010 Hyundai Santa Fe. Bought it in 2015 at 143,000km (88,856 miles) I'm the 2nd owner. It now has 204,000km (126,760 miles). Since day 1 I've had problems every now and then of it turning over but not starting. Replaced the ignition column which they say is common with these SUVs.
Still been having the same issue. They checked the keys and those are fine.I had the car just completely die on me and thankfully that was just an alternator a few years ago.
No codes on it and no other explanations from anyone.�
The mechanic says he needs to duplicate what is happening to see what the issue is.
Any advice?

Thank you for your answer and being very descriptive and informative I truly do appreciate that very much. I've been having issues with this Santa Fe and I'm glad that you've given me another possibility other than the same' ol excuse or answer.

Thanks again

I will thanks. Its basically always a waiting game for it to happen again because its usually months in between incidents happening.

Hi Joe,
I've got a 2010 Santa Fe that was cranking but not starting from time to time you mentioned the crankshaft position sensor.�
I haven't done anything yet and it has happened a few more times but eventually starts.
Since then I have (2 different times) I have turned the key and heard a click and nothing else. I checked the battery and its fine, radio, interior lights, dashboard all light up properly. The 1st time I kept trying and after a day and a half it started up like it was fine.
Today was the 2nd time and I've tried it a bunch of times and it hasn't started yet.
What are your thoughts?

Thanks

Chris
