NOTE:
This bulletin applies to all vehicles equipped with a gasoline engine.
DISCUSSION:
Customer may report that the vehicle is hard to fill with fuel or that the fuel pump nozzle shuts off repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is the least likely cause of this condition. The following Diagnostic
procedure can be used to diagnose the issues.
DIAGNOSIS:
1. Is the vehicle a LX/LE/LC/L2?
a. Yes >> proceed to Step # 2
b. No >> proceed to Step # 4
2. Idle the vehicle 60 to 90 seconds upon stopping.
3. Does tank refill properly?
a. No >> proceed to Step # 4
b. Yes >> Inform the customer to idle the vehicle for 60 to 90 seconds upon stopping if vehicle was driven aggressively. This is due to the fact that
on the LX/LE/LC/L2 the fuel tank is a unique saddle tank design and needs 30 to 60 seconds while the engine is running to level the fuel in both
half's of the fuel tank. Allowing the vehicle to idle for this amount of time will let the fuel pump transfer fuel to the left side tank, opening the
control valve and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
a. Yes >> Proceed to Step # 7
b. No >> Proceed to Step # 11.
7. Reconnect the vapor recirculation tube at the fuel tank.
8. Disconnect the other end of the vapor recirculation tube at the fuel filler tube.
9. Attempt to refill fuel tank.
10. Does tank refill properly?
a. Yes >> Replace fuel filler tube.
b. No >> Replace the vapor recirculation tube.
