Injector fault tracing

Hi, I’m hoping someone more experienced can shed some light on an injector fault I’ve been getting before I start going down the wrong road.

Ive been having a recurring fault on injector 6 relating to fuel pressure below minimum trim level. I had been planning to replace injector 6 but it’s a right Censored to get to! So before I started a job I know I’ll swear at I thought I’d check the live values again. I’m now wondering if it may be injector 4 which is at fault with a high reading, and that no. 6 is underfueling to compensate? Could this be a possibility?

I’ve not had a fault code come up for injector 4 though.

I’ve attached the live values from cold and after a drive and warming up. First photo is cold and second after a drive.

Thanks all Thumbs Up

Injector 4 is by far to high....

Start changing that one...

And then measure again...

I bet, 6 will come up within normal values Best regards
