SUBJECT:
HARD START, EXTENDED CRANK WHEN HOT, AND/OR TICKING FROM ENG. (REPOSITION FUEL RAIL)
MODELS:
1991-1992 T1 SYCLONE AND 1992 TYPHOON
Owners of some 1991-1992 Syclones and 1992 Typhoons may comment that their vehicle exhibits a hard start or an extended crank when hot. Also,
some Syclone and Typhoon owners may comment that their vehicle exhibits a loud ticking noise from the engine. The ticking is usually the loudest
around the fuel injectors. The hard start/extended crank as well as the ticking noise could be a result of the fuel rail pushing down on the injectors,
allowing them to ground out between the manifold and fuel rail. Figure 1 shows the area of contact with the manifold. This condition may be corrected
by positioning the fuel rail at its maximum height.
