Car won't start (No spark)

[Xx AzN xX]

Hi everyone so the problem im having is that my car is not getting spark to any of the spark plugs. The car cranks but dosent want to start. 

Heres some back ground info. I have a 03 g35 coupe 69k miles, only modes are intake and exhaust. So this problem happened roughly 4 days ago, i went to go try to start my car and it would crank but it wouldnt start. After trying a few times it started and ran fine. Idle was good. And no codes. But as soon as i turned off the car it wouldnt start again. But now even if i try multiple tries to start it, it wont even start anymore. I scanned the car again and still it has no codes

I cheaked the battery, starter,alternator, fuel pump. All working. 

When i cheaked for spark i got nothing. No spark in any of the cylinders. 

Dose anyone know what could be causeing this?. Theres no fuse that would be related to the spark in spark plugs is there?  Please help thank you.

Could be the NATS (Nissan anti theft system). Maybe the system lost its coding to your keys or if you are using one that doesnt have the chip in place and tried to start the car.

Oh. But if thats messed up how come im still getting fuel from my fuel pump?

Oh and another thing is that when i turn my key to the "on" position the red security light is a solid red. Is that normal?

Welcome to NICO!!

I'd have a dealer take a look...

You could also use the FSM (link in my sig) to try and troubleshoot yourself, but the dealer uses scanners to diagnose problems that you don't have.

Ok got the car working, i think it was a bad chip, and i was also using a spare. All i did was get the original key and it works like new now.

I want to thank u all for helping much apprciated.

Glad to hear its working. That's the NATS kicking in.

Seems to be working as planned. No chip that is recognized, no workie

You should start your own thread and reread what you wrote

Your post makes no sense

If a vehicle starts then the engine must have turned over while cranking just prior to starting
