Known issues on the 1985 XJS. Three recalls are on federal record for this model year. The first covers the fuel tank assembly: excessive fuel vapor pressure can build after prolonged cycling and weaken the tank structure, and a resulting leak in the presence of an ignition source could cause a vehicle fire. The second covers the speed control system: dirt entering the electronically controlled valves in the cruise control actuator can keep the cruise control from disengaging under normal driving, risking a loss of control and an accident. The third covers the fuel injection system's fuel rail, where fuel can leak at the hose and clip fittings; with an ignition source present that leakage could lead to an engine compartment fire. Owners have filed 4 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a fuel line leak to servicing the cruise control actuator, it keeps you on the OEM procedure and the correct specification for your specific 1985 XJS.
