Everything turns on but car doesn't start?

[Declangibbs]

Hi I have a strange problem with my 350z.

basically every now and again I will get in the car, turn the key to position 2 and everything lights up and all electrics work but then the car won't start.

 

it won't even crank over or any noise just nothing.

 

any ideas? Thanks

Daft question I know !  you are pushing the clutch down ?

whats your power voltage at on your dials ? If its below 10v it won't start but all electronics still work.

I was thinking the same as @SHEZZA, and if you are it could be a loose connection on the clutch pedal switch.

Faulty/dirty clutch pedal switch. That was my problem a couple of years ago.

Yep clutch pedal being pressed. 

Okay thanks is it a hard job? 

[Declangibbs]

Just seen on another thread that you can adjust the switch. Will have a go at that tomorrow.

is there any other things it could be ?

Do the dash lights dim when trying to start? If so, could be loose battery connections not allowing starter motor to draw enough current and crank the engine.

Will check tomorrow but I know for a fact the terminals are all connected tight.

im starting to think it could be starter solenoid.

just seems strange that if I leave it for a minute it will start fine

Check the earth conenctions too.

I had a poor connection on the bulk head battery earth lead

Think I've got it sussed.

just looked at the clutch pedal and I can see the sensor and it's coated in blue electrical tape. Guessing someone has bypassed the sensor poorly.

guess I've found this afternoons job! 

 

Cheers guys

+1   particularly the engine to chassis that has previously been reported as an issue on a few occasions.
