Intermitent engine faults

Do you have remote central locking, and a Chipped Key? Rick

 

[Blackfox]

Remote locking. Not sure about the key. If it was a security issue would the mentioned codes come up.

Again not sure, I had an issue some time ago re CKP sensor and after trying to start many times and then establishing the CKP was bad changed it but still could not start but NATS LED was flashing fast so had to get guy in with computer to reset the NATS, all good after, Rick

 

[Blackfox]

Replaced sensor. No luck. it had the same resistance as the old one. Note: I have a ecutalk cable now and the sensor is reading rpm as the engine turns over. Also, there is no voltage supplied to this sensor with the key in the run position.

Checked the ohms on the spill solenoid and it is a little low. getting a pump control module fault code now. going to pull the pump in the next day or 2.

I guess you mean the stop solenoid on the pump? with ignition on do you have a voltage here? Rick

 

[Blackfox]

There is voltage going to the solenoid terminals.

OK can you hear it clicking as power applied and removed, if not then the solenoid is bad, Rick

Looks like a PR50 Platform Nissan r3mR

Nice looking motor I had a Japanese Import r3mR 4 years ago.

Mine was a Japanese Import so might have been a different specification but the spare key was just a straight metal key the other two keys had remote locking buttons and there was no imobilizer fitted on mine.

Just to close the loop on this issue. Turned out to be the pump. Burnt up pump ecu. Took the pump out, bought a new Bosch ecu out of Japan. Local diesel shop calibrated the pump. Put it back in and away she went.

Ouch a costly fix but good to hear that you got it sorted in the end, thanks for letting us know. So you're all fixed up in time for winter.

 

[Blackfox]

Control module for the pump was 500 USD and calibration was about the same.

 

[solarman216]

Mmm a used pump from the UK would probably have cost about £100 plus shipping, I have certainly sold them at that price, Rick
