Yep a friend of mine told me about the pressure these things operate at i was very careful.Difficult to say but hopefully you haven’t caused your alternator to give a spike when it took up charge when the charger was switched off.
Next step is SCVs. There’s tests but only swapping them is 100% certain. You could send your ECU away to ECU doctor who would test it for you. I think he doesn’t charge unless he has to fix so might be worth having a word. I’m not sure if swapping the ECU with another truck would work, it may do but if it’s anything like my cursed Smart car, you have to change fusebox, instruments and keys to test.
Easiest step but more costly is to change SCVs. When you do this ensure the area is scrupulously clean so that not one grain of dust gets in while they are out.
Quick caution for anyone thinking of loosening nuts on the the common rail system. Use extreme caution and wear gloves and goggles plus shield with a towel when this is done. These systems operate up to 30,000 psi and there can be residual pressures after switch off. Don’t even consider it while the engine is running. Fluid can pass through skin at these pressures and the only way to get it back out is to remove flesh. Not nice! Best thing is to avoid doing it at all.
I have ordered new scv's my only concern is that the truck has gone from running poor to not running at all but i have fuel to the pump until it gets to the feed pipe to the common rail. I dont get why its not running at all
