Sorry for being long winded on this. I have a 05 Titan 4 wheel drive crewcab with 182,000 on it. Was running like a top the day I last drove it and the engine died like someone just pulled the plug on it. I was in heavy traffic and thank God I still had forward momentum and was able to pull over to the shoulder. Tried starting multiple times...nothing. At first thought I had a bad ECU relay and had a spare in my glovebox. Replaced it, nothing. Then thought it was the cam shaft sensor (I had experienced a bad sensor before). I had my truck towed back home and immediately changed the cam shaft sensor, still nothing. Then remembered about the IPDM going bad on these things, so I ordered one of the new black IPDM's to replace the old original white one. I knew this was the fix. Still nothing! Thought well how about the crank sensor, yep, replaced that too and still nothing. So much for my shooting in the dark troubleshooting. I then decided to try some starting fluid and once I sprayed it into the intake the engine came to life for a second. Hmmmm... fuel issue? I disconnected the fuel quick disconnect on the engine and when I did there was no fuel coming out. Dry as a bone. I turned the key to the "on" position and the fuel pump is supposed to spin and pressurizes the system for a second or two. I couldn't hear any fuel pump spinning and still no fuel out of the disconnected hose. I did this multiple times and then try just cranking the engine for 10 seconds or so. Starter would spin the engine but still no fuel from hose. My fuel gauge said 1/4 tank of gas by the way. So I figured it had to be the fuel pump. I did check for power at the connector (black wire with yellow stripe) on the IPDM for the fuel pump and yes I had power from the connector for a second or two (like it's supposed to) by watching my voltmeter while cycling the ignition switch to "on". (Therory of operation...After the engine starts, the cam shaft sensor sends a signal to the ECM that the engine is running and then the fuel pump stays energized. It's only when you turn ignition to the "on" position that the pump is initially energized for a second or two to pressurize the fuel circuit allowing the engine to start. If engine doesn't start, fuel pump does not keep spinning.) I pulled the rock shield off around my fuel tank and asked my wife to turn the key to only the "on" position. I finally was able to hear the pump spin for a second or two and quit. did this several times to make sure I wasn't hearing things. The pump is pretty quiet. So I knew I had power to the pump. I started to drop the tank and noticed it was pretty light, plus I was not able to siphon any gas out of the fuel tank when I disconnected the fuel filler hose (thought maybe the hose was not getting down into the area where the gas was!) I shook the tank and the damn thing was empty - dry as a bone. I had run out of gas! Nissan has a recall on the pump (NHTSA Campaign ID Number: (Recall #) 10V074000) for the 2005 - 2009 Titan and Armadas to replace the fuel sender unit inside the tank for this exact same reason. However when I called my dealership they looked up my VIN and said it was not one of the 2005 Titans that was supposed to have this repair done. I will be looking into this and contacting Nissan headquarters soon. So I have the tank removed, which was a little bit of a PITA due to the evap hose connector hard as crap to remove then to try and work on the top of the tank to remove the fuel line disconnect and electrical connector was a pain also. Especially working in your driveway with the truck jacked up in the rear end. I'm getting too old for this nonsense! I should have listened to my buddy and disconnected the bed on one side, loosen bolts on the other side and jack the bed up, but I'm a one man shop here. I have the new NISSAN factory fuel pump, hoping it will last longer than the AutoZone type cheap-o fuel pump assemblies. It was $325 online from Conyers Nissan and hope I never have to do this job again. I am putting it all back together this weekend and I let you know if it worked or not. I feel pretty confident this is my problem. Should have grabbed the bottle of starting fluid from the get-go. I would have more cash in my pocket now if I did!
