In What Order Are The Fuel Injectors On A 2001 Bmw 330ci Numbered?

January 7th, 2010 Posted in BMW

Hey guys,
So I’m trying to replace 2 fuel injectors, my diag. computer tells me that injector number 1 and number 4 are bad. Only problem is I don’t know which injectors 1 and 4 are (doh).
I have a 2001 330ci, so it should be an inline 6…
does injector 1 start at the side closest to the bumper or vice versa?
Anyone know?

    The injectors are number the same as the cylinder, starting at the front of the engine,closest to the front bumper, #1 to #6, #6 being at the very back, closest to the firewall(bulkhead). Hopes this helps, Make sure you check your connections on the injectors, no corrosion and good contact.
