Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
One of the most common causes for this fault here is a weak fuel pump needing replaced.It may be heard to run and you may have fuel in the tank but it may not be producing enough fuel pressure to allow the engine to start.
If you have not had a fuel pressure test done this should be done to see if this is the cause here.
The other common component is the crank sensor intermittently acting up.This is located at the back of the engine where the engine bolts up to the transmission.

It sounds more like a crank sensor fault here from what is described.The picture is from the top and should be where the top of the transmission bolts to the engine at the back of the engine up front.
It is usually held in with one bolt and a wiring connector.You dont have to disconnect the battery when replacing it but you can if you want to be safe on this.
