So a few months ago (before I gave up and parked the car) my maxima threw both belts on the highway. It turned out the crank pulley had separated and ate the crank sensor as well. So after I replaced all these things, both belts, crank pulley, and both crank sensors the car has a hard time starting. It just cranks and cranks then finally starts, although once it's warmed up it has stranded me more than once. It just keeps cranking. Like I said I replaced both crank sensors, plugs, fuel filter, I cleaned the throttle body, and I ran a ground wire from the trans to the negative terminal on the battery. I'm completely at a loss. I don't have the heart to get rid of the car but this is a bad issue. The only code that came up is the knock sensor, but I've been told that wouldn't cause this issue.

 

How's the harness on that crank sensor that the pulley took out?

Replaced with OEM or aftermarket?

 

The harness was in fine shape and I replaced with a duralast part from Autozone.

 

Perhaps the main ground wire is corroded.

Please attach a jumper cable on a nut on the engine, and the other end to the negative terminal. Start the car. If it starts better, replace the main ground cable which connects the engine block to the battery. I helped another member with this same issue.
