Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Do you mean not reaching the fuel injectors or not making it past the fuel injectors and into the engine/intake manifold? If the later, check the injector fuse/s.
Ok, how are you confirming this? Is there a Schrader valve on the fuel rail or some other way you are confirming this? Do you happen to know the fuel pressure?
None at all? Did you check the fuel pressure?
Is there a Schrader valve on the fuel rail? If not, you could probably install a T fitting that usually come with a fuel pressure tester and hook it up right in front of the fuel filter. It should be 34-43 psi.
If it's low, make sure the fuel pressure regulator diaphragm isn't busted and allowing the fuel to just reroute back to the tank without building up pressure. Usually when they bust if you pull the vacuum hose off of the regulator, it will have gas in the vacuum line and the regulator should be on the fuel rail. If the pressure is good or even too high, check for a smashed fuel line between the filter and the fuel rail.
If it is small and looks like an air conditioner line test connection, then it's the Schrader valve and the fuel pressure can be checked right there.
It's getting late and I am going to bed, I'm tired. Let me know tomorrow or post tonite and I'll read it by noon tomorrow and reply back. I just don't want you to think I am ignoring you, just incase you reply and I don't respond.
Ok, I am awake now, so let me know when you get the results.
OK, I have given you just about every possibility anyhow.
