I've got an '11 Equator with 55k and a 4.0 v6. I've had it for about 6 months now and noticed every once in a while, it cranks a little long to start. This issue has progressed to full-on no start (twice now). I have no engine codes. I have called the local Nissan dealer and they are stumped.
The first time it happened, I checked for blown fuses and bad grounds. I eventually assumed I had some water in my gas (froze in the line) I had just fueled up the day before, and it was 5 deg F when I tried to start. I got the turbo heater out, warmed it up, and it did start after a lot of cranking. I put in some "heat" and assumed I was good to go.
Now the other day it did it again, but I learned a little more... I was desperate to get it going because I had to get somewhere. I cranked and cranked. (pausing a few times to let the starter cool). I could smell gas, and hear the fuel pump. Finally I could start to hear the battery dragging down and as soon as the trip computer blacked out (too low of voltage), it sputtered! It was very rhythmic crank 2 seconds, sputter, crank to seconds, sputter. It never actually started though, and I had drained my battery enough that it stopped cranking. I put my booster pack on it and it cranked nice and fast again - but no sputter???
Now it becomes repeatable: I cranked until the trip computer blacked out and it sputtered again. I got the timing of the sputters figured out and I let go of the key when the next sputter was supposed to hit - boom now it's running.
I'm at a loss. Everyone I've talked to says a crank position sensor fault will throw an engine code. I don't know enough about how this thing runs to take it beyond that.
Thanks in advance!
