On the 1990-1996 Nissan 300ZX, the Z32 300ZX Twin Turbo fuel system components degrade with age, causing significant reliability issues. The fuel injectors become clogged or develop poor spray patterns, fuel dampers can leak, and the rubber fuel lines become brittle and crack. The extremely tight engine bay makes fuel line inspection difficult, and leaking fuel near hot turbo components creates a serious fire risk. The factory fuel lines use rubber hoses with spring clamps that weaken over time. This is considered the most critical maintenance item on the Z32TT.
Perform a full fuel-system inspection with the plenum area exposed, checking injector balance/resistance, all under-plenum rubber hoses, the fuel pressure regulator and damper, and every hose connection for seepage or cracking. Replace aged rubber feed/return hoses with modern EFI-rated fuel hose and new fuel-injection clamps, and on Z32TTs it is common to replace all injectors or convert early-style injectors to the later Nissan-style units while the plenum is off; any leaking damper, regulator, or brittle connector should be renewed at the same time. After reassembly, prime the system, verify base fuel pressure and injector operation, and confirm there are no leaks with the engine running and under heat soak. Typical cost is about $800-$1,500 for hoses, regulator/damper, and labor, but a full under-plenum service with six injectors can run $1,500-$3,000+ depending on parts choice and shop rates.

On the 1990-1996 Nissan 300ZX 3.0L VG30DETT Twin-Turbo V6, the Z32 Twin Turbo has over 100 vacuum hoses that deteriorate with age, causing a cascade of problems including boost leaks, erratic idle, failed boost transitions, and check engine lights. The rubber hoses become hard and brittle after 25+ years, cracking and splitting. The complex vacuum system controls boost, EGR, HVAC, and fuel pressure regulation. A single cracked hose can cause multiple symptoms.
Replace ALL vacuum hoses proactively with silicone vacuum hose. Z1 Motorsports sells a complete silicone vacuum hose kit ($80-$150) with color-coded hoses for easy identification. This is a full-day job requiring patience and labeling of every connection before removal. Take extensive photos before disconnecting anything. The Nissan FSM vacuum diagrams are essential reference.

On the 1990-1996 Nissan 300ZX, the Crank Angle Sensor (CAS) on the VG30DE and VG30DETT engines is located inside the distributor and is a common failure point on both naturally aspirated and twin turbo Z32 models. The CAS provides timing information to the ECU, and when it fails, the engine will not start or will stall intermittently. The internal optical sensor deteriorates with heat and age. CAS failure is one of the most common reasons for Z32 no-start conditions. Replacement requires distributor removal.

On the 1990-1996 Nissan 300ZX, the Z32 300ZX HICAS (High Capacity Actively Controlled Steering) and standard power steering systems develop leaks from aged hoses, the power steering rack, and the HICAS actuator. The HICAS system adds rear-wheel steering capability but also adds complexity and more potential leak points. Power steering fluid can leak onto the exhaust or hot engine components, creating smoke and fire risk. Many owners delete the HICAS system and convert to a standard power steering setup to eliminate the rear steer complexity.
Inspect the entire hydraulic system with the car clean and full of the correct ATF/power steering fluid, paying close attention to the pump high-pressure hose, reservoir return hoses, steering rack boots/seals, and on HICAS-equipped cars the rear steering lines and actuator for wetness or seepage. Replace any cracked rubber hoses, leaking rack or HICAS components, and copper sealing washers, then flush and bleed the system; if the rear HICAS hardware is leaking or the owner wants improved reliability, a HICAS delete kit with the proper lockout bar and power steering line conversion is a common permanent fix. Also clean any fluid from the exhaust/manifolds immediately and verify the pump has not been damaged by running low on fluid. Typical repair cost ranges from about $150-$400 for hoses and fluid service, $600-$1,200 for steering rack or HICAS component replacement, and roughly $300-$800 for a HICAS delete depending on parts and labor.
