Top 10 Hyundai Motor 2003 Sonata Questions & Answers

This is the problem with fuel intake lining which has air outlet which may be blocked ,you nay need to replace fuel lining from tank to refueling opening...

Good luck...

it sounds like you have a broken cable that connects from the inside of the car to the release of the gas tank. now the other release ( you said the book says is in the trunk on the lefthand-side ) it is probably under the lining of the trunk because most of them are not in plan sight for you to see.

Often there are 'UNUSED' wire harness connectors in various places on vehicles (i.e., heated seats for example when the vehicle didn't come with them). The best solution is to find out what trouble code exists in the SRSCM (Supplemental Restraint System Control Module). There are over 100 different codes/troubles which can turn on the AirBag light. Take the veh in to a Hyundai dealership to find out what code(s) has/have been stored in the SRSCM -- it simply might be a "History" code, like DSAB (Driver's Side Air Bag) Resistance - High - H. Hyundai Dealerships use two different scanning systems - HighScan and GDS. Once you find out which code, you can go to http://www.hmaservice.com/ and register and access all the info you want about your Sonata. CAUTION: Air Bag systems encorporate explosive components - trust the professionals

There are Two Balance Shafts on the 2.4. Did your mechanic also change the balance shaft belt when he changed the timing belt? If he didn't, you'll want to do that. Since you mentioned the old belt was missing teeth, those loose teeth flying around could have damaged the crank position sensor and sensor blade (tone wheel). Also, the front balance shaft (on the side of the engine nearest the radiator), has THREE different positions when the timing mark is lined up - here's the glitch - ONLY ONE of them is the correct one - this is probably where your vibration is.

I read on another site to check the "yellow" connector under the passenger seat. Connector ncould be loose or wires that go in the connector may be loose.

i have doubt about, how to test the Igniter of Huyndai sonata2003 model. the car doesn't start and i am in a way that i want to fix the problem by myself

Vehicles Covered: Hyundai Sonata 2002-2004 (2.4L & 2.7L Engines)

In 2003, Hyundai produced two types of Sonata:
Available engines:
4 Cylinders 2.4L VIN "S", MFI DOHC - see Figures 1 and 3.
6 Cylinders 2.7L VIN "H", MFI DOHC - see Figures 2 and 3.

To differentiate between these types of 2003 Hyundai Sonatas, the VIN 8th digit (Engine Type) will either be "S" or "H" as in the table above.

To locate the Engine drive belt, jack up the vehicle & place it onto jack stands, then slide under the car (toss a cardboard mat down first), then, once under the car, remove the (plastic) engine splash shield. Once removed, the drive & accessory belts are easily observed.

The "COMPRESSOR" refers to the A/C compressor, and "GENERATOR" refers to the Alternator.

Inspection - Drivebelt and Accessory Belts

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. Worn or damaged drive belts should be replaced.

Drivebelt Removal & Installation - 2003 Sonata (2.4L and 2.7L engines)

Raise and support the vehicle.
Remove the engine splash shield.
Rotate the drive belt tensioner clockwise to release the drive belt tension.
Remove the drive belt from the alternator.
Slowly release the drive belt tensioner.
Remove the drive belt from the accessory drive pulleys.

To install:

Install the drive belt to the accessory drive pulley.
Rotate the drive belt tensioner clockwise.
Install the drive belt to the alternator.
Ensure the drive belt is properly aligned and seated into the grooves of the accessory drive pulleys.
Slowly release the drive belt tensioner
Install the engine splash shield.
Lower the vehicle.

Here's the best illustration I can find of the Hyundai 2.4L and 2.7L engines - the drivebelt seems to be located on the passenger side of both of these transversely mounted engines.

Is your wiper fluid level good?Look for leaks at pump,it's connected to container,also check your hoses leaving pump to windshield,could be loose or binding.

Sounds like it might have leaked out all of the coolant and you might have cooked the engine.

If the motor is gone you may have to disconnect it and manually move it . Tough luck man you don't want that to leak. I'd make sure the fuse and relay was good first then check the switch. You could always access the motor and try to direct wire the motor to see if you can get it to move if none of these work like I said earlier disconnect and manually close it. Good luck.
