Описание: Got it 👍
Here’s a clear, mechanic-style guide for Toyota Land Cruiser starting problem + how to check fuel pressure. This is useful whether it’s hard start, no start, or long cranking.
🚗 Toyota Land Cruiser – Starting Problem (Common Causes)
1️⃣ Weak / Dead Battery
Symptoms
Slow cranking
Clicking sound
Dashboard lights dim
Check
Battery voltage: 12.6V (engine OFF)
While cranking: not below 10V
2️⃣ Starter Motor Problem
Symptoms
One click, engine doesn’t turn
Starts sometimes, sometimes not
Check
Tap starter lightly (temporary test)
Check starter relay & wiring
3️⃣ Fuel Problem (Very Common)
If engine cranks but doesn’t start, fuel pressure is the first thing to check 👇
⛽ How to Check Fuel Pressure (Land Cruiser)
🔧 Tools Needed
Fuel pressure gauge
Safety gloves
📍 Where to Connect
Petrol models: fuel rail service port
Diesel models: low-pressure line before fuel pump
✅ Fuel Pressure Values (Petrol)
Engine Type
Normal Pressure
V6 / V8
38–44 PSI (2.6–3.0 bar)
EFI system
Stable, no drop
⚠️ If pressure is low or zero, engine will not start.
🔍 If Fuel Pressure Is LOW
Check these parts:
🔹 Fuel pump (very common issue)
🔹 Fuel filter (clogged)
🔹 Fuel pump relay
🔹 Weak fuel pump wiring
🔹 Pressure regulator
🔍 If Fuel Pressure Drops After Turning OFF
Leaking injector
Faulty pressure regulator
Bad check valve in fuel pump
🛢️ Diesel Land Cruiser (1HZ / 1VD / D-4D)
Common issues
Air in fuel line
Weak supply pump
Blocked diesel filter
Faulty suction control valve (SCV)
Test
Hand-prime pump → if it starts after priming = fuel supply issue
🧠 Quick Diagnosis Trick
Spray starting fluid (petrol engine only)
Starts for 1–2 seconds → fuel problem confirmed
