  1. Material Needed.
  2. Step 1: Make sure the key is off.
  3. Step 2: Remove injector wiring harness.
  4. Step 3: Set DVOM to measure ohms.
  5. Step 4: Test resistance with DVOM.
  6. Step 5: Repeat with all injectors.
  7. Step 1: Turn the car on.
  8. Step 2: Set up DVOM to measure DC voltage.

Do I need high or low impedance injectors?

How do I know if my injector is low impedance or high impedance? You can measure the resistance across the two electrical terminals of the injector. If the resistance is between 1.5 and 4.0 Ohm you have low impedance injectors. If the resistance is between 8 and 16 Ohm you have high impedance injectors.

Where can I get a fuel injector wiring harness?

For fuel injectors, or fuel injection wiring harnesses or connectors, check out O’Reilly Auto Parts.

Why does my car have no pulse to injectors?

P0193 can be due to disconnected fuel pressure sensor hose. It can also be caused by excessive cranking without engine starting so we should not worry about this as it is the injectors that are not working. Lets try this. With test light connected to injector RED wire. Turn ignition on. Test light should come on. Crank engine.

Why is there no spark at the injectors?

The engine in 4.6L v-8 there is spark but no pulsing at the injectors. It was the PCM power relay that was bad cost me $34.00 all fixed I love this site. helpful? The security system can cause non starting. If there is a fault with the security system, the THEFT indicator light would glow or flash rapidly after ignition key is turned ON.

Why are the Spider injectors leaking in the L35 engine?

The spider system uses a central pump with 6 tubes connected to it that lead to each of the 4.3L vortec cylinders. In the L35 and LF6 engines, the spider injectors are known to leak at the pressure regulator and at the supply and return lines due to a design fault.
