hello again,

its my diesel again! its been running ok exept now and then when i take a sharp turn or over a bump the ecu light will come on for a while ie 1-2 mins with no effect to the engine, so i took it to a friend of a friends garage who has a diagnostic machine i think it was called a diag 3 oh and im in france which has made communication a large problem. anyway he plugged it in and i believe he cleared some faults which i couldnt read as they were in french and he then started the car, now i have no rev counter with a lumpy tick over with the engine management light permenantly on it also takes a good few turns to start, previous to this i have had the diesel pump changed, leak off pipes changed, a non return valve fitted to the fuel return pipe. there was also a fault code found in england (also a non vauxhall garage) called a engine speed input circuit-what is this?, i have changed the charged pressure sensor, but no diff.what the f**k is going on. help !! :cry:

please help!:shame:

Hi TellboyO

I have got a 1998 Astra 2ltr Di which had a no engine speed fault and it turned out to be the crank sensor, which plugs in at the front of the engine at the top right.
It was very easy to replace as it is only held in by one screw into the engine block.
Hope this helps
