Checking Electric Feed Pump
GENERAL
Type
The electrical feed pump consists of a PWM controlled electrical motor and a gear pump.
Characteristic
The resistance between terminal #1 and #2 should be approximately 3 - 5 Ω at +20 °C.
Other information
None.

CHECKING THE ELECTRIC FEED PUMP
Check 1
Measure the resistance between feed pump's terminal pin #1 and #2. The value should be approximately 3 - 5 Ω at +20 °C.
Check 2
Measure the resistance between the feed pump casing and terminal pin #1. The value should be much greater or infinite.
Check 3
Measure the resistance between the feed pump casing and terminal pin #2. The value should be much greater or infinite.
