THIKPO Fuel Injector Tester & Cleaner Kit — Dual-Channel, 8 Pulse Modes, 8 Adapters

THIKPO's Universal Fuel Injector Tester and Cleaner Kit is a portable, dual-channel tool that diagnoses and cleans gasoline fuel injectors using eight pulse modes and eight adapter sizes.

This compact kit combines a multi-mode pulse generator, two-channel output, and a set of adapters to let DIY mechanics and technicians test, compare, and flush petrol fuel injectors without removing the entire rail. It supports simultaneous testing of two injectors, offers selectable 12V/5V drive levels, and includes protection against reverse polarity and short circuits. The removable adapters cover a wide range of injector geometries, and the LCD displays the active pulse mode for straightforward troubleshooting.

How does this tool identify common injector problems?

The tester simulates injector pulses to reveal issues such as clogged nozzles, electrical failure, or uneven spray patterns. By switching pulse lengths and voltages, you can see whether an injector responds consistently under different conditions. Using the included adapters, you can also run a pressurized cleaning cycle to remove deposits while observing injector behavior.

• Eight pulse modes: short, medium, long, continuous combined with high/low voltage
• Dual output lets you compare two injectors side-by-side
• LCD shows current pulse mode for repeatable testing
• Reverse-polarity and short-circuit protection for safe operation

What vehicles and injectors will these adapters fit?

The kit targets most 12V electronic fuel injection (EFI) and gasoline direct injection (GDI) systems on petrol-powered cars. Included are eight generic sizes that match a broad range of domestic and import injectors plus two specialized fittings for VW/Audi and BMW N-series injectors. Note that diesel mechanical injectors are not supported.

• Eight-size adapter set covers common small and large injector bores
• Special adapter for VW/Audi-style injectors and threaded BMW N-series adapter
• Compatible with 12V EFI and GDI petrol injectors only (not diesel mechanical)
• Adapters allow pressurized cleaning while monitoring injector response

How do the pulse modes and power options improve diagnostics?

Multiple pulse durations and two drive voltages let you recreate different engine conditions to test injector timing, response speed, and flow consistency. Short pulses show rapid response, medium or long pulses expose flow issues, and continuous mode helps when cleaning. Switching between 12V and 5V drive simulates real-world electrical conditions for more accurate analysis.

• Four pulse lengths plus continuous output for varied test scenarios
• Selectable 12V (high) and 5V (low) drive to mimic system voltages
• Pulse patterns reveal clogging, sticking, or electrical faults
• Works with a fuel pressure gauge for off-engine diagnostics

What safety and power requirements should I know?

The unit includes protections for reverse connection and shorted outputs; indicator lights warn when a fault is detected. It runs from a 12V vehicle battery or an external 12V DC adapter rated at least 1.5A. For cleaning operations, prepare a compatible injector cleaner and a separate 12V power source before you begin.

• Reverse-polarity protection prevents damage from incorrect hookup
• Output short-circuit protection flashes the power indicator if tripped
• Powered by 12V battery or external 12V/1.5A+ adapter
• Requires separate cleaning fluid and battery or adapter (not included)

Who this kit is for: THIKPO's tester and cleaner is suited to home mechanics, small-shop technicians, and automotive hobbyists who want to diagnose and restore gasoline injectors without relying on dealer-only equipment. It's practical for anyone who needs a portable, multi-mode tester that covers most 12V EFI and GDI injectors, compares two injectors at once, and supports off-engine cleaning when combined with a pressure gauge and cleaning fluid.
