So I’m trying to get my RAM Ecodiesel back on the road, it will crank and crank and crank, has ~4200psi at the fuel rail, injectors have been tested and one has been replaced, it shows RPM when cranking so don’t think it’s the reluctor wheel, tested compression and found no loss, lift pump has been tested. I’m at a loss right now
