Hi still need help with a 4.6 range rover m reg , back fires and only just runs for a few seconds but is very erratic, backfires when turning over .
replaced the coil pack,plugs, leads , compression check is fine , fuel pressure fine , cam and crank sensor fine. clean fuel, had a crypton tune guy out but the computer plug in is not recognising his machine so he is a bit limited however all the checks above have been done .
is it possible to slip a tooth on the timing chain?
it would appear that the firing order was wrong as it sounds like its running on crossed leads but they are in the right order.
could the new coil pack be duff?
help !!!!! its my 1st range rover and at this rate it might be my last
any help will be appreciated
