280zx Fever,

To rule out #2, #3 ecu input to the injectors try the following.

You will nead a basic auto elec test light (twin diode type, red & green) about $35.00 AUS if you have to buy one, borrowing is better. Clip the light lead to the fuel injection manifold. with the engine running place the pointy end of the light into the back of the fuel injector loom plug on both wires. the idea of this test is firstly, establish that lights activate on both loom plugs. You should see the light flash at a constant rate on and off. to confirm what you are seeing is correct functionallity check a known working injector loom plug for the same light and rate. also confirm your results for both wires. You could have a faulty dropping resistor or connections.

cheers

Will this work with a normal test pencil. I have the same problem (except none are firing), I have voltage going to both wires of the injector, and when I test with the pencil it just sort of dims on and off
