Car Died While Driving, Now Will Not Start. No Codes.
 

Hi all, been a lurker on this forum since I got my Z last year. Used a lot of the DIY's for springs and other minor troubleshooting, but now I have this issue.

I searched the forum/web on this one, tried multiple methods/fixes (outlined below), still will not start.

Here's how it started... I'm from AZ, so no real weather conditions here this time of year, But I was driving in the morning to work and about a mile in, the just car died, the symptoms made it feel like I just ran out of gas (electronics still on). I had a full tank though.

Just add this tid-bit, it was after a right turn, but I was a red light. I didn't accelerate hard out of the turn so I don't believe this to be an issue.

I towed it back to my house, got my battery tested just in case. It was low, but got I it charged and put it back in but no success. I did buy some starter fluid and this made it seem like the car wanted to turn over a bit more, but never fully started.

Considering, that the starter fluid helped somewhat, I ended up replacing the fuel pump, with the newer version, mine is an 09. The old pump's housing seemed a bit damaged since one of the rods (non-spring) was hanging lower. I put in the whole new assembly (OEM), but still no dice.I feel resistance on my fuel line to the engine bay when the car is turned on and I hear the fuel pump kick on as well. At this point, I am leaning on that this is actually not a fuel related issue.

Checked the appropriate fuses, all is good. Unfortunately, no codes as well. This can't be the key issue since I am actually getting a crank result.

Any idea of what I should take a look for next? 09 base, no mods recently done to car. Only mods at the moment are intake/exhaust.

Thanks in advance!

new battery is a cheap fix, if thats the problem...maybe alt isnt charging, they can check that too.

Ck. Ignition Spark...gotta have fire in the wire.
fuel/compression/spark & correct timing.

I did end up trying a new battery just in case and same unfortunately. I read a lot on cam position sensor having issues, but since I had no codes, I didn't worry about it. I ended up removing the sensors and I got codes so I suspect that the OBD2 reader is functioning properly.

Crank position sensor? If you are sure you have spark and fuel, then I would check that next. They can go out and not give any codes.

Sorry to hear this man, hope it all works out.

Thank you for the advice about the crank sensor. Any idea to know if it's bad? Or do I just buy a new one and hope for the best lol

I would go ahead and change it. Very inexpensive part but extremely hard to diagnose without specialized equipment. Most people just change it out. I believe it’s located in the rear of the engine, passenger side. Good luck!

Fuel pump, fuel pump hat (breaking) and intank hoses are a common problem. Check your fuel pressure.

I'd check fuel pressure then try the crank sensor. Like posted above crank sensors can be a pain to diagnose.

Thank you for advise above. I bought the Z1 adapter plate with the gauge earlier this week and got yesterday. I installed it and got 40 psi, so I should be good to go. I am planning to grab a new crank sensor from Nissan today so I will throw that in and let you know how it goes.

Just throwing this out there since my Honda back in the day did this. Can it be a bad main relay? Clutch relay?

Update?

Currently waiting for my crank sensor to come in. I double checked every fuse with a multimeter just incase. So as of right now just praying it is the crank.

Update:

So I ended up replacing the crank sensor. Before I put the new one in though, I attempted to start the car with it off and it started right up. I put the new one in and unfortunately no start.

Any thoughts of where to try next? Is it timing issue? Thanks!
