Hyundai Kona: Fuel Delivery System / Fuel Pump Repair procedures

Inspection

1.	Turn the ignition switch OFF, and then remove battery (-) terminal.

2.	Remove the fuel pump assembly.

Using an ohmmeter, measure the resistance between terminals 1 and 6 of sender connector (A) at each float level.

Pin No	Description
1	Fuel sender ground (-)
2	Fuel pressure sensor (FPS) signal input
3	Fuel pressure sensor (FPS) ground (-)
4	Ground
5	CAN [Low]
6	Fuel sender signal (+)
7	-
8	Fuel pressure sensor (FPS) power supply (+5V)
9	CAN [High]
10	Battery power (B+)

Also, check that the resistance changes smoothly when the float moves from "E" to "F".
