Hi - sorry this is my 1st post
I have a 2002 BMW 530i E39 - it starts from cold fine but occasionaly after a short run - it wont start up. The engine turns over and I can hear the fuel pump running but it does not fire up. If I leave it for a while and go back to it - it starts. I have chnaged and air filter. - but its made no difference. Because its so intermittent - it is hard to diagnose - for example - it wasnt starting so I took one coil off, plugged a spark plug in and checked it sparked - it did - but the car started as well!
Not a power problem - starter turns over fast when it doesnt start. - Have changed the battery anyway, but no difference to the fault. Also put a new set of plugs and filters in. Have also changed the crankshaft sensor. Will be changing the 2 camshaft sensors next. Its only done 70,000 miles and never been abused.
