it cranks won't fire or not getting any fuel
2003 nissan atimal it cranks won't fire or not getting any fuel don't hear fuel pump when come on.
Is this a good question?
mitchell1 you are not telling us what you have checked regarding the fuel situation. Now here is how it all works according to the SM:"
The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump." So what the means is that you need to check your pump, the relay after that the POS and the camshaft position sensor as well as all the wiring in between. Then if still no error found you need to check the ECM.
Without sending you on a wild goose chase I recommend that you check the fuel pump fuse (see image for loaction)
Next is the fuel pump relay
FUEL PUMP RELAY
Ignition switch: ON (Engine stopped)
Turn the fuel pump relay “ON” and “OFF” using CONSULT-II and listen to operating sound
Fuel pump relay makes the operating sound.
CHECK ITEM (REMEDY
Harness and connectors
Fuel pump relay
The relay is built into IPDM E/R
