Engine cut out problems

tintin · 3rd February 2018, 19:30

Good evening all,
Have got a problem with my zt-t diesel, it has cut out 3 times now (whilst accelerating and stationary at a junction)! The car has started again usually after the 2nd attempt and has been ok until the next time.
It is now parked on the drive and won't be moving for fear of being stranded!

I have checked a few obvious things like the battery terminals and easy to reach connectors but everything seems ok.

The last time it cut out the engine management light together with the oil light were flashing intermittently with the associated clicking noise from the ECM behind the glovebox. (Oil level is fine)?

The car has got fitted one of these tune up boxes connected to the MAF! I will disconnect this and return the car to standard before I do anything else, But can anyone help as to where to start looking and any common or possible causes ??

Many Thanks,
Tintin

Your CANBUS processor has bought the farm

The ECM is or has been wet, and requires repair, the oil lamp flickering is a classic sign, especially when you associate it with the fuel pump relay chattering in the passenger compartment fusebox.

Drop me a PM if you need it fixing

Have you tried simply disconnecting the MAF sensor? It stopped mine cutting out and jerking, randomly at times, although it was not accompanied by ANYclicking or dashboard lights. New MAF sensor has sorted mine. However, Brian knows so much about these, he's probably certain about your symptoms.

I hope when you disconnected the above tuner it was not replaced after you got the car sorted, I am sure advise was given to not to

Hello
The plenum chamber was full of water and had just reached the level of the ECU hence the problems. Brian's diagnosis was spot on as was big Russ s.
All sorted now though.
