I need some help on this issue ive been having with my titan.2007 Titan, 75,000 miles.The problem that im having is when the temp outside is cold approx 35 F or so, the engine wont start.it cranks fine,it has a new battery,just had it check out.I have added fuel additives in case there's water in the tank.I also always try to keep the tank at least 3/4 full.This morning just about kill the battery trying to start it.I put the charger on,went inside for several hours (4) while it charged.About noon time,tried to start it and it cranked right up.I'm open for suggestions.

Don't crank too long. Unburned fuel has to go somewhere.

When the ECU relay goes bad I think the engine will turn but won't fire. Might want to try the relay. Swap it with the other relay which I can't for the life of me remember it's name. Or, just go to the dealer and buy one for about $5. You should keep one as a spare anyhow.

I drove the vehicle to the local advance auto where they did a load check on the battery.If am not mistaken the battery that i have is rated at 550 cca.The load test gave the battery 547 cca at the time it was tested.I have addedd a bottle of heet just incase there was moisture in the line.I have also noted while i was doing the center console mod that there seems to be something inside the dash that turns on and off momentarily while the ignition is off.Also i have replaced the IPDM.It was replaced it last month because the vehicle would not start.After i replaced it, it started right up.As of now i Have to wait until the weather gets cold again.

Same sort of issue....had to have it towed to the dealership last Wednesday. Dealer spent a bunch of time diagnosing, decided it was a bad IPDM, so they replaced with the newest IPDM, which has a lot less relays onboard. Called me Friday nite to say it was repaired. Went to pick up the truck Saturday morning, temp was ~30 degrees. Truck WOULD NOT start!! Service manager came in later in the afternoon, truck started fine, killed it and tried to restart...no-start again!

Tech came in Monday morning, truck started fine, kept starting all day long. He cleaned and retightened all the grounds, but couldn't find anything that should have caused the no-start condition.

This morning (Tuesday), the truck cranked for a time, then started.

Truck is an 08 XE CC, no remote start, no chips in keys.....no real mods. It started fine during cold last winter......

Same issues with my truck.Once it starts,it'll keep starting all day regardless if is cold or hot.As long as the weather is warm is fine it starts right up.If the temp goes down to about 25-30 degrees normally it will not start.I have since also replaced the fuel pump.

Mine received a new battery (750CCA) in late October after the Nissan replacement installed 10/2011 developed a bad cell. The ECU relay was replaced by Nissan 12/2011. Vehicle has only 24000 miles, I keep maintenance current and don't abuse the vehicle.

Dealer stated they checked the fuel pump and filter, found no issues, no codes set. Only thing was that the there was a CAN communication issue with the IPDM, which the service manager stated was usually an indication of IPDM breakdown and failure.
