Hi my name is***** will be glad to help. Thank you for the detailed description of your symptoms and test results. That is a confirmation of a faulty injection pump in need of removal and rebuild or replacement. With good fuel supply, the fuel should spray out of a cracked open injection line or there are internal problems. Let me know if you need more help. Please take a moment to rate my service. 5 star and bonuses are greatly appreciated.
