Leaky injector cm2350

[joed2323]

Tried doing the fuel system leak test thru insite and the fuel rail pressure drops on its ass from 29200 clear below 20000 in about 10-30secs easy.

I assumed it was a faulty fuel rail pressure relief valve on the rail, so I swapped it and still drops like a rock.

So, how do I pin point which injector is dumping fuel?

I did the cyl cutout test and that didnt help.

Id rather not take the truck to kw and give them my money, do they sell a kit to isolate the injectors?

The older cm871s are fairly easy to check which injector is bad but this is a cm2350
