Message	You are losing fuel pressure most likely because the orings got pinched when installing that new injector. What happens is the fuel system should hold pressure until the next start and this likely isn't the case. What you need to do is put a fuel pressure gauge inline and watch the pressure when you turn the key off. If it goes down with the key off, you've got a leak. Some bleed off is normal but it should hold pressure. The next test you will need to do it pinch the return line and see if the pressure bleeds off. If it doesn't your leak is not in the injectors. If it does, then you will need to pressurize again and pinch the return fuel line and the send line, making sure the fuel pressure gauge is isolated inside with the injectors. If the pressure bleeds off, you've found your leak. Injector(s). Good luck.
