Hello Folks,
My 1991 V12 5.3 Marelli Ign has A Bank not firing. Have determined leads Ok. Nothing coming out of the A Bank coil. 1st stop thinking of changing the coil. Has anyone had this prob and can advise and perhaps direct me to other things to check. Is it easy to check the coil? Thinking to change the coil anyway and if it is’nt that i hav’nt wasted my money. Any advice appreciated. Charlie.

If nothing’s coming out of A bank coil, it’s usually either the coil or the amp. You can swap amps or coils to determine which.

Just for my education, is the A coil the forward-most one, or rear?
Thanks,
