Known issues on the 1990 XJS. Three recalls are on federal record for this model year. The first covers the ignition system: the high tension lead from the ignition coil can shift closer to the #4A fuel injector hose, causing the injector hoses to crack or split from ozone deterioration and expel fuel into the engine compartment, a fire risk near any ignition source. The second covers the fuel tank assembly: excessive fuel vapor pressure after prolonged cycling can weaken the tank structure, leading to leaks that can result in a vehicle fire. The third covers the vehicle speed control system, where dirt entering the electronically controlled valves in the cruise control actuator can keep the cruise control from disengaging under normal driving conditions, risking loss of control and an accident. Owners have filed 18 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a fuel line for cracking, inspecting the tank structure, or servicing the cruise control actuator, it keeps you on the OEM specification for your specific 1990 XJS.
