yes please help ,03 G35 cranks but wont start.....what is causing the fuel pump not to run check fuel pump it was goodwhat could be causing the car to shut it off

 

Did you check for spark, crank sensor, or any codes?

 

check your fuses under the hood. There should be one for the pump.

 

There is a relay like 2one mentioned behind the battery. You'll need a multimeter though and some alligator clips to check it properly. You'll want to check all the terminals and see which two have continuity with no power supplied. Then connect one terminal to positive and the other to negative on those terminals and it should click. Which, means the electro magnetic coil is working inside, but then you need to find which terminals have continuity while the power is supplied.

I can't remember if it's a four, five, or six pin relay, so that's why I am giving generic instructions.
