Because your car "Does not fire" indicates a electrical problem as in a coil, wiring etc -- not lack of fuel. If you mean that you actually have no fuel than yes you may have a fuel pump or pump relay problem. A fuel pressure test would determine - but I agree, replacing a relay is a easy start and very well could be a problem.Hi Folks,
My 07 Sentra cranks but does not fire. I suspect it could be the fuel pump / relay. I'm having trouble finding the relay, and how to go about testing it. Can I test at the pump to see if it is receiving power .
