I just recently bought my dreamed car - 350Z, 2004 - VQ35DE.
The problem is, that the car wont start, it has blown motor - or to be more concrete, motor is knocking during trying to start it.
I was buying this car through dealer as it was already promoted as with motor failure, so I knew that the motor needs to be rebuild anyway, but I would like to just hear the car starting to get the idea if I should try to rebuild the engine or just buy new one. I just need to hear it also to be sure, that there aren't any other problems - such as with electronics, ECU and I can just simply focus on rebuilding the engine.
ECU does not show any error, or at least my diagnose does not show anything. I just try to reset the ECU and other ideas which I found on this forum. During starting I found out, that it does not give the petrol to the engine and because of that the engine does not start. ECU was during reset procedure blinking fast ten times, ten times and again ten times - it tells error 0000, isn't it?
I searched already here for a while - tried to synchronize keys, reset ECU ... But still the car does not pump the petrol to the engine, what can be the issue? Is there some ECU protection which will prevent of starting engine after the engine fails?
Other interesting problem is, that instrument cluster behaves weird - when I put the key to the "on" position, it immediately shows normal temperature of motor, 1000 rpm, speed on 50Km/h...
So, you bought a wreck of a car and are surprised there are issues? That is like buying a nasty ***** and not wrapping up and wondering why it burns to pee...
Ah, nice reply. For those with slow thinking, I was buying it on purpose, because I know that I want it on turbo for the future, so I would have to build motor anyway. I just need to hear the motor running to diagnose what happened. And to decide if I should build this engine on buy new one. And also, when I put the built engine back I would like to be sure, that everything else, except the engine is ok. I hope it is more clear now. My brother is mechanic, has built many engines till now and also has built some custom turbo cars.
But for now we are having issue to start the engine. The motor spins, it has a pressure. Only on one side it is heard that it will be probably knocking. So there is no reason why it should not start at least...
Please would be so kind and keep your sarcastic reactions.

Geez i wonder why....maybe... just maybe... the MOTOR IS FREAKING BLOWN
OK, one more time. The motor does have pressures, it is no reason why it should not start at least on 5 cylinders.
I am wondering more on the electronics - has anyone ever seen instrument cluster showing some weird values before start - such as speed at some point, rpm... ? I have tried the test procedure of instrument cluster and that was working properly - gauges went from bottom to the end as they should.

if your brother has "built many engines till now and also has built some custom turbo cars" then he should be able to find the issue
Of course he is doing it now, but for now we are trying to diagnose why even pump does not pump the fuel when ignition is set to on. That is why I am asking here, I thought that you guys has much more experience with this car. He has built many engines but not on 350Z yet and does not have experience whit this concrete electronics, so of course he has schematic and trying to slowly process with multimeter...
I was expecting that maybe someone of you guys would have some hint, at the end we dont even need to hear the engine running but all prerequsity needs to be working - we have checked that it gives a spark, but does not pump the fuel to the engine, the pump is just silent...
Yes that is going to be next step, that we will unplug relay of the pump and give it directly 12V. But it seems to me less probable, especially after I red a lot of problems from people here on forum with NATS, IPDM, ECU, Cam shaft sensor, Crankshaft sensor and so on. Especially when the gauges act weird, so I will check the pump now and will come with results, but dont think that is the issue.

Send me the car, I have diagnosed it with a dumb azz owner and will swap owners, I will also remove junk motor and install 8 cylinders of american fury
Pull some plugs and sniff for gas. If yes, refer to this-
Good luck, let us know when you solve it!
Thank you very much for your respond. Will definitely let you know the progress.
I am sorry now for such thread I made, I was not thinking that people will be so offensive here. I have the car just for couple of days, so didnt check all possibilities which we had on mind, but something like your post I was expecting, so thank you, that at least there is someone on the other side of earth with reasonable thinking.

Sounds like you got some fun electrical problems with the bad motor. When you say the ECU doesn't show any errors are you using an OBD2 reader or are just trying to count lights? Also that is not normal behavior of the gauge cluster.

We have just Delphi diagnosis, it can read at least engine codes and I was also trying to count lights.
Btw we have just confirmed, that pump is burned, so I will order some high flow fuel pump. But still gauges behaviour is too weird, any idea here?

Dead engine does not start
