FUEL SYSTEM AND THROTTLE BODY 13-5
• Connect a proper lead wire into the fuel pump coupler (fuel
pump side) and apply 12 volts to the fuel pump (between ter-
minal A and terminal B) and check the fuel pressure.
Battery + terminal terminal A (Red wire)
Battery - terminal terminal B (Black wire)
Fuel pressure: Approx. 294 kPa (2.94 kgf/cm
2
, 41.81 psi)
If the fuel pressure is lower than the specification, inspect the
following items:
* Fuel hose leakage
* Clogged fuel filter
* Pressure regulator
* Fuel pump
If the fuel pressure is higher than the specification, inspect the
following items:
* Fuel pump
* Pressure regulator
FUEL PUMP INSPECTION
Connect a proper lead wire into the fuel pump coupler (fuel
pump side) and apply 12 volts to the fuel pump (above) and
check that the fuel pump operates.
If the fuel pump motor does not make operating sound, replace
the fuel pump with a new one.
If the fuel pump is OK, the cause may lie in the TO sensor or TO
sensor circuit. (12-48)
* Before removing the special tools, disconnect the
battery and release the fuel pressure slowly.
* Gasoline is highly flammable and explosive. Keep
heat, sparks and flame away.
