Kia Troubleshooting Questions? Ask a Mechanic
Hi Im David, thanks for visiting the site. When you turn the key to the run position does the fuel gauge do its normal sweep?
on the sweep it should go to full then back down to 0 then to the level of gas thats in the vehicle.
of course I do, please standby
ok. heres a wiring diagram. it goes from the pump/sending unit to the computer at position 27 of connector B-01C
I think you need to check for continuity and for high resistance of the wiring between the computer and sending unit. just to check the integrity of that part of the circuit
yes you are.
yes you can still ask questions for as long as you'd like. just get with me when you are ready tomorrow.
hows it going?
you disconnect the fuel pump sending unit. you disconnect the connector at the pcm. you put one meter lead on the green wire in the fuel pumps connector and the other lead in position 27 of connector b-01c of the pcm, turn the meter to ohms and see what the reading is.
ok, same time here
When you found the ecm connector in water, did any penetrate inside of the connector?
all you need to do is to check the connector for good grounds and if they are good, dont worry about where g21 or g29 is.
