This summary uses the existing diagnostic information shown in full below.
Your car's computer thinks there's a big hole somewhere in the fuel system, which means gas might be leaking out.
The engine control module (ECM) has detected a large leak in the fuel system, which could lead to reduced fuel pressure and performance issues.
The P0093 code indicates that the ECM has detected a fuel system leak that exceeds the allowable threshold. This could be due to a physical leak in the fuel lines, injectors, or fuel tank, or a malfunctioning component that is causing a drop in fuel pressure.
• Strong smell of fuel
• Decreased fuel efficiency
• Engine misfires or stalls
• Damaged or leaking fuel lines
• Faulty fuel injectors
• Cracked or damaged fuel tank
ECM: Engine Control Module, the computer that controls engine functions.
Fuel Pressure: The force at which fuel is delivered to the engine.
• Inspect fuel lines and connections for visible leaks.
• Check fuel tank for cracks or damage.
• Use a fuel pressure gauge to test for pressure drops.
• Replace damaged fuel lines.
• Repair or replace the fuel tank if cracked.
• Inspect and replace faulty fuel injectors.
• Fuel pressure gauge
• Leak detection kit
• Basic hand tools
$150 - $600
Moderate
• Toyota Hilux
• Ford Ranger
• Chevrolet Silverado
• Regularly inspect fuel lines and connections.
• Avoid overfilling the fuel tank.
• Use high-quality fuel to prevent deposits.
Fuel System Issue
• Do not ignore the smell of fuel; it could indicate a serious leak.
• Have your vehicle inspected by a professional if you suspect a fuel leak.
Check with your vehicle manufacturer for warranty coverage on fuel system components.
The P0093 code has been associated with vehicles experiencing significant fuel system leaks, often due to aging components or physical damage.
High – A fuel leak can be dangerous and should be addressed immediately to prevent fire hazards.
Operating a vehicle with a fuel leak can pose serious safety risks and may violate emissions regulations.
• Engine running
• Fuel system pressurized
The fuel system components are located along the fuel lines, from the fuel tank to the engine.
Q: Can I drive with a P0093 code?
A: It's not recommended to drive with a P0093 code, as a fuel leak can be dangerous and lead to a fire.
Q: How do I know if my car has a fuel leak?
A: You might notice a strong smell of gasoline, reduced fuel efficiency, or see visible fuel under the car.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
