325_driver 422 Report post Posted December 24, 2008 Have been looking every where Any one know the order in which injectors fire or if they are batch fired (e.g. batches cylinders 1,3 then 2,4 then 5,6 ) Where do you reckon i could get this information? Any help on that would be greatly appreciated Next, Any one had a fuel pressure regulator with problems ? I have a sluggish car at the moment, and think its fuel related, Fuel filters new enough, but going to replace it any way, what can i expect if the fuel pressure regulator is playing up or needs replacing ? Thanks heaps MERRY CHRISTMAS ! Quote Share this post Link to post Share on other sites

325_driver 422 Report post Posted December 24, 2008 Any help? so the injectors fire the same as the spark ?? Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted December 24, 2008 so the injectors fire the same as the spark ?? I doubt it - they're probably batch fire ---> all at once. If they are paired it would be 1+6, 5+2, 3+4, but I don't think the E30s had any sort of sequential fire (happy to be proved wrong). Quote Share this post Link to post Share on other sites

I would have thought it was the same sequence as the spark but just slightly earlier? Quote Share this post Link to post Share on other sites
CamB 48 Report post Posted December 24, 2008 I would have thought it was the same sequence as the spark but just slightly earlier? On your car, yes. E30 is too old. I am pretty sure it has some sort of batch fire - it might split them into pairs or threes (that's usual), but am pretty sure the computer only knows crank angle not cam position. Ok did some more research (I want to know) - they are two groups, odd and even - page 34 of this 16mb doc: http://shark.armchair.mb.ca/~dave/BMW/e30/e30_89.pdf I looked at the '84 diagram and 123 and 456 are grouped.

Not sure whether this is a deed end to my power loss in the e30. Quote Share this post Link to post Share on other sites
