04 sonata 2.4 issue
Hello all
i have a 04 sonata 2.4 with a strange issue. Randomly won't start but if I cycle key 2-3 times with out cranking it will fire up. I am leaning to the fuel pump but it will suddenly die after driving as well when at idle not on acceleration when I punch it it goes no problems. No check engine light on do codes and yes I have scanned it. I would figure if it was the fuel pump it would stumble on acceleration. All cylinders above 170psi. Fuel pressure at or around 35-36 when I tast it but I can't guarantee this reading because the problem randomly happens no rhyme or reason. I just replaced both coils on the vehicle because they were out of spec. Car has 186000 miles on it again no codes when it dies which leads me to a mechanical issue some where that the sensors can't trip for any ideas?

Cycling the key to the on position a few times, it indicates the fuel is the issue
Whether it is the pump or leaky injector or regulator, just can't tell.
Fuel pressure sounds a little low.
Good luck
