Engine will crank but not start, also before this happened I was driving down the road and it just stalled.
If you want to keep guessing, you just might get lucky after you've spent hundreds of dollars on parts you don't/didn't need. If you could tell us which (if any) DTC's (Diagnostic Trouble Code) are stored in the ECU (Engine Control Unit), we might be able to help you identify the problem and cause. The other solution is tow the vehicle to the nearest Hyundai Service Dept and have a qualified technician diagnose the problem. They'll give you an estimate of repairs (parts, labor, tax, time frame, etc.).
When you disconnected the intake air hose & sprayed starter fluid into the throttle body, you removed the Mass Air Flow Sensor. The intake air hose MUST be connected so the computer knows what the airflow is so it can adjust the "air-to-fuel_ratio. - it didn't do this because it wasn't connected and that's why "the engine started but ran rough and then died."
The fuel filter is located underneath the vehicle near the fuel tank, left side (driver's side) below the left rear passenger seat. Recommend you NOT Replace it until you have verified that the fuel perssure is low at the fuel rail. It may not be the filter that's causing the problem -- it may be the pump itself. Verify fuel pressure first.
FUEL PRESSURE TEST [2.4 I4]
1.
Turn the ignition switch to the OFF position.
2.
Apply battery voltage to the fuel pump drive connector to check that the pumpoperates.
The fuel pump is in-tank type and its operating sound is hard to hear withoutreoving the fuel tank cap.
3.
Pinch the hose to check that fuel pressure is felt.
FUEL PRESSURE TEST [2.4 I4]
1.
Reduce the internal pressure of the fuel pipes and hoses by the followingprocedures.
A.
Open the trunk door and disconnect the fuel pump harness connector in thetrunk room
B.
Start the engine and after it stalls, turn the ignition switch to the OFFposition.
C.
Disconnect the battery negative (-) terminal.
D.
Connect the fuel pump harness connector.
2.
Remove the bolt connecting the fuel line to the fuel delivery pipe.
Cover the hose connection with a shop towel to prevent splashing of fuel causedby fuel residual pressure in the fuel line.
3.
Using the fuel pressure gauge adapter, install the fuel-pressure gauge tothe fuel pressure gauge adaptor. Tighten the bolt to the specified torque.
Fuel pressure gauge to fuel delivery pipe
25~35 Nm (250~350 kg·cm, 18~26 lb·ft)
4.
Connect the battery's negative (-) terminal.
5.
Apply battery voltage to the terminal for the pump drive and activate thefuel pump: then, with fuel pressure applied, check for fuel leakage from thepressure gauge or connection part.
6.
Start and run the engine at curb idle speed.
7.
Disconnect the vacuum hose from the pressure regulator, and plug the end ofthe hose. Measure the fuel pressure at idle.
Standard value :
320~340 kPa (3.26~3.47 kg/cm², 46~49 psi)
Something eles you should be aware. When the timing belt was replaced, was the balance belt also replaced? It's necessary to replace it as well when the timing belt is replaced. If the balance belt broke, it probably damaged the crank sensor & tone wheel (blalde). The tone wheel (blade) needs to be inspected to see if it has been damaged - if it has, you don't want to reuse it -- get a new one - please don't try to straighten it out if it's bent. If it's not perfectrly straight, it can damage the new crank sensor.

I have a 4 cylinder, it has 105,000 miles on it, the timing belt was changed at 60,000 miles. At first we thought it might be the fuel pump but that is working, The reason for that thought was we sprayed starting fluid into the intake and the car started but wouldnt continue to run. Engine light didnt come on before it stalled while driving down the road. It was kicking and bucking before this happened, so we changed the wires and plugs and also one power pack. oil always gets changed every 3,000.
where is the fuel filter and how do we change it. we do alot of our own due to the money situation. cant afford to take it to Hyundai. We will be testing for a spark tomorrow, there was no idiot lite that came on when the car died. gave it fuel starter into the intake valve and the engine started but ran rough and then died. thanks for any help that you can give will right more tomorrow.
Thank you for all your help with my car, a friend of ours came over with the code reader and it says that the crank sensor is not working. So from what I do know it has to be purchased at the dealer, however I am going to look on ebay first, because their cost at the dealer is about $200.00. But I need to look at Ebay first. Thank you again and I will recommend this site to all my friends.
Thanks Heidi
Dear Ghost4548, I need your assistance please. We are picking up the crank sensor today and hopefully putting it on too. Do you know where it is located on my 2003 Hyundai Santa Fe 4 cylinder? Pictures and or a description would be most helpful, and maybe some info on replacing it? Anything would be helpful to us. This is the code that my car was displaying that was not working. And is there another sensor that maybe a part of it not working that should be replaced with this one. Thank you and have a good day. Heidi
And you know the fuel pump is good because it is running and you verified actual pressure output?
Need more information. The 03 Santa Fe came with three different engines. Which engine do you have? the 2.4I (4 cylinder), the 2.7 V6?.. or the 3.5 V6? How many miles on the vehicle?... Has the timing belt been replaced at 60,000 miles? Could be anything!... Did the 'Check Engine' light come ON?
Can't help with anything specific...you dont have enough info. Offhand first place to look is fuel filter, and crank sensor. BUT without proper testing I would not buy anything till you have tested for fuel delivery and spark. A code test would also be helpful.
Problems stalling while driving. Most recently happened while doing 110km/hr. Problem happens when fuel tank below 3/4 of a tank
