Engine - Hot Fuel Starvation Above 4000 FT. Elevation
Number 86-6(Gasoline)-15A Date 3/86Subject: HOT FUEL STARVATION AT ALTITUDE (ABOVE 4000 FT. ELEVATION)
1982-84 PHOENIX AND 1982-85 6000 WITH 2.8L-V6 ENGINE (LE2, VIN CODE X)
In high altitude areas with high ambient temperatures, some 6000's and Phoenix models with 2.8L-V6 (LE2, VIN Code X) engine may experience a no-start condition after a short hot soak (10-45 minutes). Other vehicles may start and then stop running immediately thereafter. These vehicles will not restart until the engine has cooled down. This condition may be caused by fuel starvation (vapor lock) and can be corrected by installing Electric Fuel Pump Kit, P/N 14094438. This kit utilizes a low pressure (3psi) electric in-tank pump.
Included with the kit are detailed instruction sheets for installing all parts found in the kit. In addition to installing the kit, the float level in the carburetor should be adjusted to compensate for the change in fuel pressure caused by the addition of the in-tank electric pump. Use procedures found in Section 6C3 of the shop manual to adjust the float levels. Float levels for 1983, 1984, and 1985 vehicles should be reset to 1/4 inch (6.5 mm). Float levels for 1982 vehicles should be reset to 3/8 inch (9.5 mm).
