Subject:
COLD START VALVE THERMAL AND TIME SWITCH WIRING HARNESS INTERCHANGED
Model and Year:
1986 PONTIAC 6000 MODELS EQUIPPED WITH 2.8L (RPO LB6) ENGINE
TO:
ALL PONTIAC DEALERS
General Motors has determined that some 1986 Pontiac 6000 models equipped with 2.8L (RPO LB6) engine may have two circuit wires interchanged in
the cold start valve thermal and time switch.
This can result in a grounding of the cold start injector power circuit. This grounding can blow the 10 amp fuse in the crank cavity. Thereafter, the cold
start injector will not operate causing difficult or no starting..
To correct this condition, the circuit wires will be inspected, and if required, be reversed and the "crank" fuse replaced per instructions in this bulletin.
