SOURCE: 2001 Hyundai Accent cranks, won't start

its the camshaft position sensor . Its located (atleast on my 1.6L) to the right of the front HOT plate the conection runs between the engine and the right side fan. easier to work on if you take off the air intake thats by the left front side of the battery. you will be working between the fan and the motor. only one bolt but is tricky so u need a 1/4 inch nuckle with a 1/4 extention. once located and you have the right tools it will only take 30 minutes to replace....dont forget to take off negative battery cable before you start.

SOURCE: Lights come on. I hear one crank but car won't start

Will the wipers work with the key in the run position? If not, it's the battery. Try a jump start. If the battery's ok you need to measure volts and amps at the starter to check for clean connections and internal failures.

03 Santa Fe car sometimes won't start but only when immobilizer light stays on will start after a while has power just wount start


Yes. Immobilizer lamps that stay on or continue flashing indicate the vehicles immobilizer has not recognized a valid key. Depending on the system, the vehicle may start with a correct rotation but invalid key, or it may not crank. Your problem us most likely a defective key, however the immobilizer antenna could also be weak and not properly picking up the key. Both problems will require a dealer or technician or locksmith with special tools to learn new keys to your immobilizer.

RESTART VEHICLE AFTER BATTERY CHANGED


Computer reset for starters
Second alternator is failing get tested
Third fuel filter and pump
These are the norms for routine maintenance with battery change
Since battery died we know it wasnt getting voltage on the road
Or it was getting it intermitently
The alternator can pass tests intermitently
When checked
The best old fasioned way of testing alternator run vehicle disconnect from battery positve side
Let run if power drop or car stops alternator needs replaced
Battery is only good for starting a vehicle
All other power like accessories comes from a transformer in vehicle that stores voltage
Youll see in car a second bar with ground and power going to it this is your transformer do not jump accross transformer
Other then mentioned above routine maintenance is needed

2004 sonata will not start


Filling up the gas tank can stir up the fuel fumes. You may need to check your evap system? I can't rule out bad gas?
When the problem is ongoing, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. With intermittent issues, need to test when problem is ongoing. How long since a tune-up? Any applicable trouble codes?
Problems at higher rpms, the basics, you check for a blockage of some kind, fuel--air--exhaust.

My hyandai sonata only starts when i press the immobiliser however the immobiliser is not working and i have replaced the batteries i need my car can u pls help?


Take the batteries out and put them back in again. Make sure they are in correctly. Try the immobilizer again. If it still does not work, reverse the batteries and try again. If that doesn't work you may have to contact a Hyundai dealership for help.
