Have you tested fuel pressure output from the new pump that was installed at all?

Have you tested injector pulse signals at all?

Customer reply replied 11 months ago
no
Infiniti Mechanic: peterpete190, Auto Technician replied 11 months ago

O.k.,at each injector one wire at each injector should have 12 volts DC with the key on or when cranking over the engine.Can you test to see if you have this 12 volt signal and let me know?

ill have to check other than that is ther anything else that can limit fuel intake, vapor lock? regulator?
Infiniti Mechanic: peterpete190, Auto Technician replied 11 months ago

If the fuel pump is pumping and is pumping pressure to the engine and your not getting any fuel into the engine this indicates the injectors either do not have the 12 volt signal and this can be due to a blown fuse needing replaced so all fuses need checked.Or the injectors are not receiving the ground pulse ( this is the second wire at each injector,they should all have a ground pulse off/on signal when cranking over the engine).If it is not seeing this ground pulse this can be the engine computer at fault as it controls the ground pulse signals.I have also seen a faulty cam sensor cause this issue as well with no ground pulse signal.These are the only components I see on this model here to cause this fault needing checked into.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
