Hi all
Wondering if anyone has this problem and fixes.
Currently have faults on several codes in the listed dtc,s. Have replaced all the coils and plugs.
Still have codes for the same coils, but they are still firing.
Differant injectors fire when first start then fail after starting.
The particular coils aren’t,t getting a fire signal, so it’s a signal problem to injector, but as mentioned the same fault codes are appearing.
I have also disconnected look and checked resistance to the injectors, all fine.

Any thoughts would be appreciated
Cheers

what are the DTC's that show up

Plus your starting point with these problems is to Check your grounds. Especially block to battery negative.
