Hello everyone
I'm french sorry for my English
I come to you because I have a problem that I can not solve
I explain the problem
i was driving and suddenly the engine stopped, she did not start again
the following days she started when she wanted
a shot she starts, she has her power, another shot it starts but does not go up in the turns / minutes
it is rare that it turns a long time, as soon as the engine starts the engine cuts directly after
when the engine does not crack, I am only the starter who turns
I have ignition, my pressure at the ramp is good
I wrote well "attempting to start" in green, the pmh oscilloscope looks good to me (I am not a pro)
but the engine does not crack
I change my pmh sensor and camshaft
check all my relays
check all the probes
my engine compressions are ok
is it possible that his come from the calculator? I have a DTA S60
or so of my car
it looks a little like an anti-start, but I'm not on my car
thank you for your help

Re: engine that starts when he wants
If this happens often, can you datalog the event happening ?
When it stops, can you stop the car, leave the ignition turned on, and verify the ecu is on, or off ? Or can you keep a laptop connected to monitor the ecu and sensors when this happens ?

Re: engine that starts when he wants
at this moment it does not start, but yes how can i datalog the event ?
when it stops, the ecu i on, I have my pc connect to the ecu
when it does not start, I have each time "Rejected crank pulses" and "Crank wheel teeth errors" in the page Engine diagnostics
thanks for the help

Re: engine that starts when he wants
As it's suddenly happened, it sounds like a wiring issue.
Check all the grounds to the ECU, especially the one on the ECU case, are still connected properly.

Genial thank you are genies
problems resolved, calculator mass was failing (bounds 13 and 14)
I have it directly grounded battery, no more problems

Re: engine that starts when he wants
Hello
I shouted victory too fast
it lasted a week and she does it again
now she starts all the time
but when she is hot, she stops suddenly
either she reboots well and cuts
either it starts but no longer goes up in the towers
I moved the masses many times, I rebuilt a mass on chassis, always the same
the mass on ecu is well connect the same for the other mass
thanks for your help

Re: engine that starts when he wants
Are you getting any crank sensor errors in the diagnostics?

but sometimes yes I have
but sometimes yes I have

Re: engine that starts when he wants
If it's cutting out without throwing any errors, you either have a fueling compensation kicking in, or you have a loose wire somewhere on the output side.

Re: engine that starts when he wants
everything is well cabled
after best observation, she cuts when she is hot , cold it works nickel
especially when the oil rises in temperature, it cuts and when I restart it works in degrade mode
yet I am not an oil temperature sensor connected to the ecu
