I'm having difficulty troubleshooting an issue starting my 1997 Pulsar N15 (also known as Nissan Centra, Nissan Almera in other countries).
If the car has been sitting for a few hours (or overnight), it takes about 20-30 seconds to get going.
Initially my mechanic diagnosed that fuel pressure drops to zero once vehicle is turned off, then has to rebuild pressure to injectors to restart vehicle.
Since then, we have:
- Replaced Fuel Pump (with new)
- Replaced Fuel Pressure Regulator (with second-hand)
- Upper engine de-coke
- Cleaned Throttle Body and Air Idle Motor.
- Several applications of Fuel System Concentrate
So far I've spent over $500 with no change to the starting characteristics.
I've posted a 50 second video of car starting at http://youtu.be/CVvK7-gmtCY
Does anyone have any ideas for further diagnosing the problem?
