Question about 2003 Kia Sorento
Fuel pump sensor has 2 wires onto high pressure pump. One wire is ignition live. It's the second wire I can't work out. Should it be an earth? Trying to figure if sensor is faulty Thanks in advance for any help

Does it cranks when you turn on the key to start.-------- If its not cranking then get the coil and spark plugs checked.-------- Also is the fuel pump coming on when you turn the key on.-------I agree fuel pump is replaced, but is it coming on when you turn the key to on.If the fuel pump is not coming on then get the fuel pump relay inspected in engine compartment fuse box under hood or give direct 12 volt power to fuel pump and turn on the key and see , if fuel pump runs or not.--------- ----------- when you start the car, does the starter gets power, test it with meter. Test the voltages to battery, starter and alternator.--- If battery is weak car will not start, if battery connections are dirty or loose car will not start.If battery to starter connection is loose car will not start, if starter is weak, the car will not start.If fuel pump is not getting voltage the car will not start.-------- So once you confirm that battery, starter , fuel pump all are getting power and all are working, then get the coil pack and spark plugs inspected.This will help.To confirm where the problem lies.Thanks.Helpmech.

I have 2005 Kia Sportage with a check engine light. No other symptoms. I was told by Kia and Local mechanic that it is the fuel injectors. Error Code states that Fuel injectors are running lean. Put Master airflow- no change. Ran engine test with propane to run rich and trim never changed from 15. Car runs great. Kia dealer said that this is because we use Ethel in gas that it effects the alumium fuel rail delivery to the injectors and that it is necessary to change all of them .Kia Dealer wants $1,000.00 deposit to place order 6 fuel injectors from Kia. (Has anyone heard of that?)Also put fuel injector cleaner in tank.Does anyone have any suggestions before I spend over $1,000.00 to replace all 6 injectors or possible idea of what could be wrong?

Remove the accelerator and cruise control cables.
Remove the engine coolant hose and throttle body.
Remove the P.C.V. hose and brake booster vacuum hoses.
Disconnect the vacuum hose connections.
6. Remove the surge tank stay.
Bleed off the pressure in the fuel pipe line to prevent the fuel from spilling & squirting you in the eye.
Disconnect the connector from high pressure hose.
9. Remove the surge tank and gasket...be careful with gasket, you can reuse it.
11. Remove the delivery pipe with the fuel injector and the pressure regulator....
When the delivery pipe is removed, be careful not to drop an injector.
Disconnect the wiring harness of the coolant sensor assembly.
Remove the surge tank.
Ignition coils and ignition wires:
disconnect ignition coil harness connectors
disconnect ignition wires from ignition coils
remove hold down bolts from ignition coils
while gently twisting pull up and remove ignition coils
while gently twisting pull up and remove ignition wires
remove spark plugs (always check gap on new plugs, even if they say they are "pre-gapped" )
Install in reverse order, don't over torque anything and keep your work area clean. Now would be a good time for wire replacement too---depending on the mileage on your Kia
Do a good visual inspection of hoses, clamps, wires & pulleys while you have it "opened up" ---Good luck, thanks for using fixya and i hope you get many more trouble free miles out of your Sorento. =)
