I have a 2005 Nissan Note (Auto) that has recently developed an intermittent engine malfunction, like when we are accelerating from a paused position, doing approx 30-40 km per hour, the engine suddenly dies, or the same thing happens when driving slowly at approx same speed... after the engine dies, of course the dash lights all come on, and we lose steering control, at this point i have to dangerously pull over and put auto into park before i can restart engine, but always starts after this situation occurs, first time. I've had an auto electrician check it out, and reports back that the computer, coils, sensors, etc are all ok... however the problem is still there, so any suggestions how to diagnose/fix this problem would be most appreciated?, thanks

fuel pump pressure would be the first thing to check

great response, i will follow up on the piece of advice, and let you know how we get on, many thanks for that, as sure the mechanic never checked this?

Also check age and condition of sparkplugs as old ones with wide gaps can easily overheat causing misfiring and failure until cooler.

It should start if you knock the gear selector into neutral whilst you are still moving (definitely not park when still moving) doesn't solve the problem though.

Were there no stored fault codes?

(My old corsa flagged up "Injector fault cylinder 3" when I tried to start it with no fuel pressure.)

Thank you all for the great tips/support, so just reporting back / confirming that the problem was indeed the fuel pump pressure, was funny, as the auto electrician was stumped, so i mentioned to him that i had been advised by a "Note" specialist, to check the fuel pump pressure... hence to the mechanics surprise when he discovered this was indeed the culprit causing the problem, he replaced it with a second hand fuel pump 2 days ago, at a cost of $280 nz and hasn't died since, so big thanks to mdvineng, you saved the day, one thing though, it now has like a flat spot when you accelerate, i asked the technician can he adjust the throttle to how it was, and he said that they have a self learning throttle system, and will adjust itself to the correct position in a few days of use, so wondering if this is in fact correct?... as never heard of this system/set up before, anyway thanks again for the support
...cheers, mike

most modern ecu's are self learning if you remove the battery for 15-20 the ecu resets its self to default
the more you drive the car the more the ecu learns (adjusts the fuel, timing, ect)

check the plugs and give it a oil/filter change

thanks for that, and yep plugs and oil change was carried out last month, was surprised how expensive the plugs are on the Notes... $60.00 each (ouch)

ecu- electronic control unit, some people also call it 'the black box' though most of the time they are silver in colour! may take you a while to learn some of our abbreviations and acronyms but there's always someone who can help.
