Compression test - dimkozi - 25:th-Apr-2017

Hello everyone,

Want to do a compression test on my petrol Astra J...how long should I wait for the car to stall after I remove the fuel pump relay???

Tried the other day and it was it was idling for 20-30 mins without stalling...is that normal???

Cheers

Hi,

I'm not a mechanic but I would of thought it would of stalled quite quickly.
