5. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
2 and 6.
Resistance: 0.2 - 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
6. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 2 of
the connector, and the negative (-) lead to terminal 6. Check
that the fuel pump operates.
NOTICE:

These tests must be performed quickly (within 10 se-
conds) to prevent the coil from burning out.

Keep the fuel pump as far away from the battery as
possible.

Always perform switching at the battery side.
If operation is not as specified, replace the fuel pump or lead
wire.
