No Injector output

[sh944s]

I installed my MS3 and began the running the test sequences for injectors and coils. The injector test gauges appear to show the injectors pulsing but the injectors are not responding. I checked the wiring in vehicle and it rings out fine. I took the unit out of the car and attached the Stimulator. Ran the test for injectors and again the gauges indicate pulsing but no injector LEDs. I removed the daughter card and tested the injector circuits by grounding U1 pin 21 and 22. Leds on the Stimulator lit when grounded.

I searched the forums and others suggested loading new firmware. Loaded the firmware but the problem persists.

Any idea where to go from here?

Ok, Here is the MSQ file

[billr]

In TS "test mode" are you specifying inj1/L and inj2/J for testing?

[sh944s]

I was specifying INJ1A and INJ2B. I am batch firing,now that I look at the drop down menu am I specifying them incorrectly? Should I be using a different designation?

Thanks,

[billr]

Well, I'm confused. When I open your MSQ I see no options for testing "Inj1A" or "Inj2B"; only "InjA" and "InjB" and the "Inj1/L" and "Inj2/J" already mentioned.

[sh944s]

Sorry my bad. You are correct INjA and INjB.

[billr]

Let us know what you get trying Inj1/L and Inj2/J

[sh944s]

OK, that worked. Thanks for the help. What is the difference between InjA and Inj1/L? Did I miss something in the documentation that would have helped me pick the correct value?

Thanks again.

I don't think I can explain perfectly, but the lettered injector outputs generally refer to outputs from the MS3X board; the numbered ones (1 and 2) are the "standard" one on the mainboard.
