Name is Greg, My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

Just an idea what your problem may be ,remove the fuel pick up and check for filter blockage had this with a sportage 2.0L could be your problem .

Fuel level and pick up is under the rear seat .

Please check this out then get back to me if needed.

Hi Greg


thanks the filters have been cleaned and replaced the problem seems to be fuel pressure but we don't know where this could be as all filters pump and valve have been checked the car has been with the mechanic for 2 weeks he has checked fuel lines etc but no joy

Expert:  Greg replied 2 years ago.
Have the injectors checked as this problem is fuel delivery restriction or a fuel leak most likely internal .
Most common is the injectors have a leak down test done normally when you can't find the problem the injector are the culprit .

Do a leak down test as i think your injectors are leaking .
You may have more engine oil than you should check the oil level if you do have too much replace the injectors .

Hi


injectors checked all Ok car now going to Kia as not able to sort the problem

Expert:  Greg replied 2 years ago.
If all these are good then a known issue with the supple line having a crack and sucking in air ,mostly on top of the tank ,
You may see the tank is wet from fuel that has very slowly leaked out but no quite enought to drop onto the floor .
