Hi All,
My 1.8 X-Reg Nissan Primera is sitting in a garage after a week of trying to diagnose a problem.
Whilst driving along I accelerated the car hard to around 5500 rpm, just under the red limit. Suddenly the power dropped off and the car free wheeled to a halt and the engine stopped.
Trying to restart the car, would turn over and run for a few seconds then simply cut-off.
RAC suspected a faulty fuel pump and towed me home.
Put the car into a garage with a good mechanic who's found the fuel pump to be working fine.
Further tests he's tried to work out why it starts, then dies after 5 seconds:
- Had it hooked up to 2 separate diagnostic computers, both showed no faults other than ignition system is shutting down after 5 seconds.
- Recommended to change cam and crankshaft sensors, done this, not helped.
- Checked spark plugs are sparking, fuel injectors are working initally and then stopping.
- Checked coils, power to them initially, then power drops off.
- Checked the immobiliser is being switched off by having key and transponder checked. Both working fine.
He suspects it's maybe the ECU that's faulty, although would the diagnostic checks identify a dead ECU?
Can anyone through any more ideas into the pot, my mechanic is determined to resolve this.
Cheers
Mike
