car cuts out suddenly - 3.0 v6 with lpg
« on: 13 August 2010, 13:38:49 »

could not restart - would just turn over as if no fuel

happened again after 5 minutes - temp normal
full of petrol and at least 2/3rds tank of lpg

did the paper clip check and no faults cam up
when engine running  :-/
and 3 -1 came up when engin not running  :-?

is it expensive to change the crank sensor?

thanks

Is the idle absolutely stable?

Does it only cut out at idle?

idle is around 500 rmp and car has not cut out on idle

today is the first time it has happened and both
times whilst the car was moving?

I'd still go for crank sensor if there aren't any obvious missfires etc..

Good spot, I never looked, don't think it would make any odds if it was crank sensor at fault....

But is it crank sensor? Presumably this happened on gas?

Change it - inexpensive place to start, then you know you have a good one anyway even if it doesn't cure it

did paper clip again
no code with engine running
3-1 with engine off.

also - when the car started after maybe 10-15 minutes
it started on petrol and then went straight to gas.

will change the crank sensor and see how it goes from there!

thanks

does it normally take this long to switch over to gas? is it an auto switch over i.e. it auto starts on petrol and then auto switches to gas?
