Check to see if you have fuel pressure (49-52 psi) at the fuel rail test port. If not, your fuel pump relay or Crankshaft Position Sensor could be defective. If the Powertrain Control Module does not receive a signal from the Crank Position Sensor, The fuel pump relay will not energize and the fuel pump will not run.
