Where is the fuse box on a 2010 Nissan Sentra?
The interior fuse panel is located behind the storage compartment drawer in front of the driver’s left knee. Open the storage compartment and squeeze together the two side walls to release it from the dashboard.
Is there power going to the fuel pump?
Yes, power flows through the fuel pump relay. 1. Remove the fuel pump relay. 2. Check the relay socket for the ONLY terminal that faces differently from the other three. That is terminal #5 and feeds the load (fuel pump). You can double-verify the terminal number by checking it from underneath the relay. 3.
Why is my fuel pump not getting IGN on?
If the ECU doesn’t respond with a ground, and it is also missing on ECU pin #8, then perhaps it is not getting the IGN ON signal on ECU pin #38. If the ECU is getting the IGN ON but doesn’t respond with a ground for the fuel pump relay then it could only be either a bad ECU ground or the ECU itself.

What should crank speed be for fuel pump?
A good crank-to-start speed is about 300 rpm. Besides the rpm, another section of the CMP tells the ECU the relationship of TDC for each piston. That is how the ECU knows when to energize the ignition power transistor and fire each fuel injector.
