2003 Tiberon Gt 2.7 automatic.
Used to hesitate and sputter some, when i tried to give it more fuel, and also wouldn't go past 3000 rpm without acting up.
Left my key on overnight.
Ran the battery down.
Now it won't start.
Will run if sprayed with starting fluid.
Changed fuel pump and still have the same problem.
Please help

 

If at all possible, please don't go changing parts without confirming the part is malfunctioning or defective.
That can get to be very expensive and disappointing.

If you suspect a part to be defective,you can always ask here for a method to verify if it is good or not.
There are times special background is definitely required, and sometimes special tools.
If you feel you don't want to get involved there is no shame putting the $$$ where it will do the most good and that could be a qualifies shop.
Many companies are finding parts returned as defective are not defective, but the person changing parts only thought so.

 

I need help diagnosing the problem. And not being chastised for changing parts. The fuel pump was week and needed replaced.
Have fuel to the pressure regulator.
