Howdy all. I've got a question regarding my Nissan Armada.
Car: 2005 Nissan Armada LE
Modifications: Bully Dog GT Tuner. I have it currently set to stock settings. Also have a K&N panel filter. I've had the Bully Dog on the truck for about a year and haven't had any issues. Most of this time, I had it set to 93 octane and performance pedal response.
Description of the problem: My wife was driving home last night and the car shut down on the highway. She said the gas pedal became really hard to depress. No check engine lights or any other indicator lights. When I got to the truck, I pulled the spark plugs and they all still looked good, small hint of white on the iridium tip (NGK Iridiums). I checked and cleaned the MAF, checked and cleaned the air filter, checked oil and antifreeze. Everything looks fine. I checked for ECU codes on the Bully Dog but there were no codes.
When I tried to start the car, it would crank but won't turn over. I had the car towed home and I pulled the battery to check the voltage using my boat battery charger, it was somewhat low (50%) and the voltage was about 12.1-12.2. I charged the battery anyways.
I pulled the ECM relay as it has been known to fail on these trucks, and swapped it with the fog light relay and it still wouldn't turn over.
This morning, I hooked the battery back up after charging to 100% and it did turn over for a quick 5 secs, then it struggled to idle and died. I tried it a few more times, pumping the gas while starting but it didn't turn over anymore. It sounds like maybe spark or fuel related. Maybe the fuel condensation of sitting overnight helped it turn over? Also, could a fuel pump or alternator cause this? Is there a way to check the spark, fuel and alternator to determine what is the issue?
There are no other mechanical issues with the truck. I did notice that a few months back, I started to smell a hint of burning oil while driving, no smoke though. When I swapped over to the Rotella T6 oil, no more smell. Also, I think the injectors are loud. They ticked loud, almost like a valve tick.
Any ideas would be awesome.
Recent maintenance or modifications: Oil change 1k miles ago from conventional to Rotella T6. I don't think this would cause any issues.
