Re: Farm truck refresh
Well looks like I'm not getting a pulse signal to the injectors (at least as best as I can tell).

Re: Farm truck refresh
Got a noid light to test the injector pulse and confirmed that is the problem. I guess that means my ECM is bad...
Harness is a new swap harness, ECM has power as confirmed by the check engine light.

Re: Farm truck refresh
the injectors pulse so fast that you really can't verify if you are getting the electrical pulse without a noid light as previously mentioned.

Re: Farm truck refresh
After doing more reading I see that the injectors won't pulse unless there is spark. I'll start chasing the spark side and see where that leads...
