Thats not safety boost m8. That happens when one of the turbo's is dead. But I wouldnt have thought that would cause it to stall:confused: Maybe you have a boost hose off somewhere.

Hi,

 

try checking your power transistor unit. it is attached to the cam cover on the right hand side. This is a common problem for pre-93 production car. There is a possibility that the engine stalling might be caused by the PTU due to vibrations & heat.

 

The PTU is a pack of six power transistors which behave as solid-state relays to switch 12v current to each coil pack under the control of signals from the ECU. It is the rectangular device bolted to the right hand cam belt cover. The wiring to the PTU runs across the front of the engine, then down the left hand side, where it joins the main ECU wiring loom. Several other harnesses are taken off the PTU harness bundle on the way back to the firewall.

 

Common symptoms are:-

1- Failures can be intermittent - causing loss of ignition to one or more cylinders - or

2- Failure can be complete and sudden, causing instant stalling - very dangerous in heavy traffic

3- The component fails at 100,000-130,000 kms.

 

try the site http://www.aus300zx.com/ under the Tech section.

Its got a write up on the PTU.

The guage not going past 0 is your give-away. If you can get another gauge to check it then do so - but it looks like one of 2 things - a turbo problem - or a boost leak - with the engine running have a listen under the bonnet to see if you can hear anything.

well I've got an ex Nissan mechanic who owns and worked on 300's. He's just finished one of the guys car from here and it's purring like a kitten. He's a real genuine guy who takes pride in what he's doing. I can ask him tomorrow if you want, I can't gaurantee he'll do it cos he's real busy, but I can ask.
