My 2006 Tiburon won't start, at first it intermittently wouldn't start, then only once a day it would start and now it won't start at all. I tried to jump start it but it wouldn't start, we push started it and it started right up and ran great, turned it off and tried to restart it and it wouldn't start. All the lights on the dash work, radio works headlights work, no check engine light has came on, it just won't turn over like I don't have the clutch pushed in but I do. Any kind of help or advice would be greatly appreciated.

 

From what you describe, when you turn the key to start you get absolutely nothing from the starter.

If this is correct, you need to verify power from the ign is getting to the starter solenoid.
If it is, solenoid or starter has a problem..
If it is not getting power to the solenoid then you need to verify it is getting past the clutch safety sw on the way to the starter solenoid.
Once you have just which condition is present , you can go from there and either replacing the switch or the starter assy.

Sometimes a brush will hang up inside the starter and a few taps on the starter will allow it to start, worth a try.

 

Verify the clutch switch is operational during cranking.

 

Since we didn't hear back from you, is it safe to conclude you either solved the problem or had someone else take care of it?
