Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central. Please make sure to let me know exactly what is needed from me so I can provide EXCELLENT 5 STAR service.

If the coils are getting voltage and a ground pulse, then they should be firing the spark plugs. That test result means the coil(s) are bad. Did you get that same result on all coils?


On your screen you should see a rating 1-5 stars. Please make sure to select one. I am not compensated by the website unless a customer rates. Rating only pays me from the deposit you have already made, it does not charge you more, nor close the post. Also all follow ups are free and welcome.

Thanks Chris
