2007 international 4300, 466e, running on 4 cylinders,

Customer Question

2007 international 4300, 466e, running on 4 cylinders, 6,3,2,1 has had new valve cover gasket installed.
Just bought the truck, has 120,000 kms, previous owner said it was a nightmare
Besides not running right
The cruise, jake brake, air dump, dif loc does not work. Shows no codes.
We took off valve cover found #5 unhooked and #4 grounded out. Fixed it and truck ran very nice, once assembled still ran nice next day went to start and runs on 3 cylinders. Now on the 4 I mentioned. We have check all fuses, cleaned all grounds. Check all switches, where does a person start? Injector harness?

Hi i'm Wayne

I will help you with this

Yes start with replacing the injector harness,

if that does not help matters, then you need to remove the ECM and have it tested

I hope this helped you

Not Poor/Bad service

My dealer is saying there is not much that you can check on the ecm if the truck runs the ecm should be good. That it does not store any history.
Also any ideas why the cruise and jake brake does not work?
Expert:  Wayne replied 1 year ago.


The ECM gets signal from each cylinder,

so it can be in the ECM,

now jakes and cruise, that also goes thru the eCM<,

I suggest to have it removed and tested


I hope this helped you
