Ok I have had the common "its an injector going out" symptoms. The rough idle bucking while driving ect. Yesterday morning I got a light 7 and 3 injector circuit low voltage. I checked em again at lunch to double check what it said and now I have all 8 injectors low voltage.
I did read bad electrical system can mess a FICM up. My batteries are about done. Changed one today gotta wait till tomorrow for the other to come in.
Is there anything easy I can do to verify if the FICM is bad or is it pretty much straight foward crap. My truck is getting harder and harder to start fast. If FICM is bad I would like to change it now but don't want to pay for one if its not the problem. Can't get into dealership till wed to hook up to a scope machine for them to pin point the problem.
Any help is appreciated. Thanks.
