2005 Nissan Armada cranks no start changed fuel pump in tank replaced relay under dash unless it's not the right relay

Have you run OBD2 scan for fault codes ? What led you to change the parts you have so far ?

Your guessing ,have no clue ! Replacing parts instead of testing electical circuits an doing a diagnostic scan of all the control modules rarely work's . changed starter,fuel pump,emc and relays are good and had a new key re coded. It still will not crank. Your best bet ,take it to a qualified repair shop.

Check all earths are clean & tight

upon researching this make & model of car it seem that the fuel filter is located in the fuel tank on the fuel pump & should not need replacing unless your tank is dirty.

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

Check you fuel pump relay. located on IPDM marked as ECM relay in the picture. Just change places of ECM RELAY and FOG LAMP relay and try to start. If it starts change the ECM relay. good luck

yes you have to drop tank to replace fuel pump and filter as it is one unit pretty easy though.

crankshaft sensor is either under the harmonic balancer pully or bolted to block facing it you normally have to pull pully to change sensor but some you dont you will need a puller and a installer if you have to pull the pully

relay should be under the hood in relay area

if this was helpful please give me a good rating

tell them to replace the ecm relay....actually there should be a recall campaign for this on your vehicle.

I would start by pulling the fuel pump fuse and starting the vehicle. This will get rid of the pressure on the fuel line. Once the vehicle will not start crank it over for about 10-15 seconds. Then the fuel filter is located under the brake booster on the drivers side. It has two hose clamps that hold it on. Remove the two hose clamps and replace the filter. Then install the fuel pump fuse. Turn the key to the on position and wait till you hear the fuel pump shut off. Turn the key off and repeat this step 3 times to build fuel pressure. Then you should be ready to go!

Fuel pump is not in the tank but near the engine/ on the engine.
Broken membrane?

But then whole other list of things can be wrong.

You can dismount the fuelpump and test it by moving the eccentric handle in some leverage setup.
