525 EFI with no spark
Hi ! I have a 525 efi that has lost it spark on no 8 cylinder ?
Tryed to change plugs 2 times, plug cabel and coils on that side (4+4).
Looks like just a little bit of fuel is coming but someone told me that it shuts off fuel of there is no spark ?
Good compression aswell..
Can it be a ground problem ? Or any other ideas please ?

I had this happen recently. Double check that you have no spark as it could be a dead injector. You can do a cylinder drop test with a scan tool to shut off the injector. If not, I’d say a coil has failed
