Rb25De Neo Not Starting

[RB25DETC33]

Hey guys, so ive had a TPS issue with my r34 (fault code checked and confirmed) and after a period of driving, the cars idle and engine operation become erratic. The car then began not starting, i figured it was due to the tps. Replace the tps and the car still has a problem with not starting. When i press the accelarator down while the engine is not on I get a loud buzzing sound from deep in the engine bay, as if it is near the trans. I do have fuel pressure, not sure on spark but the buzzing is giving me concern.

Anyone had this issue?

the buzzing is because your tps is out of adjustment; you can turn your ignition to on- loosen off the screws on the tps and move it around till the buzzing stops then retighten the screws; car should then start

Thanks bud, but its not the tps, its deep down, like near the transmission. Not sure if its a solenoid or what. It only buzzes when the throttle is more than idle. There seems to be spark or there would be a code thrown up when I check the fault codes, but I get code 55.

I seem to think it could be the park neutral start switch on the gearbox. Ive taken a quick vid showing the issue:

no doubt the noise is low down but ive had the EXACT same problem on my auto 32 and the EXACT same buzzing sound and itcame from down near the trans, as soon as i had adjusted the tps it stopped

You were correct on the buzzing sounds from the tps. I adjusted the tps and the buzzing did occur in the same place, although for some reason it has not solved my problem....

at least your car is now buzz free! keep looking, youll find the problem
