SUBJECT:
LOSS OF POWER, HESITATION ON TURNS
MODELS AFFECTED:
1985-92 ELECTRA\PARK AVENUE\ULTRA MODELS 1986-92 LESABRE MODELS
CONDITION:
Some 1985-92 Electra, Park Avenue, Ultra and LeSabre models may experience a loss of power or hesitation while driving on sweeping right hand curves, such as an exit ramp, or on hard right turns, when fuel level is below a 1/4 full designation on the fuel gage.
CAUSE:
Vehicles that have the above symptoms may have fuel pumps and strainer assemblies slightly mis-positioned on the tank sending unit, allowing the strainer to not stay fully submerged in fuel.
CORRECTION:
Replace the fuel pump strainer with Part Number 25121783. This new strainer replaces the old strainer on all Nippondenso 51 mm fuel pumps and will stay submerged in fuel to prevent starvation. The Nippondenso fuel pump can be identified by the number 16, (or 51 for supercharged engines) on the I.D. Tag which is attached to the wiring harness, (see Figure 1).
