flashing, see ECM Error Codes in the Electrical Sys-
tem section.
3. Make sure there is sufficient, clean gas in the gas
tank.
4. Verify that the battery is sufficiently charged to crank
the engine over at normal speed.

ination. Clean or replace as necessary (see the Peri-
odic Maintenance section).

! WARNING
Whenever the gasline hoses are removed (other than for
pressure testing), the battery must be disconnected to
prevent inadvertent activation of the electronic fuel
pump.
! WARNING
Whenever any maintenance or inspection is performed
on the fuel system during which there may be fuel leak-
age, there should be no welding, smoking, open flames,
etc., in the area.
! WARNING
Do not turn the ignition switch to the ON position with
the hoses removed. Gasoline will be pumped by the
electric fuel pump causing a safety hazard.
! WARNING
Gasoline may be under pressure. Place an absorbent
towel under the connector to absorb any gasoline spray
when disconnecting.
