Hi, i just installed on my AFN a 11mm fuel pump from alh and sdi cam 038e. I set the timing on the 3 marks, according to autodata ilustration.
First start, white continuous smoke ( blown head gasket like), missfires in intake, runing lumpy.
I hooked vcds, dynamic timing off the chart. I retarded the pump to~60 timing. The same white smoke, engine runing lumpy, idle lumpy, low power. I played with timing from injection pump sprocket all day. Because of lumpy idle it was bouncing between how i set it and 38. For example in vcds injection start spec is 5 deg BTDC and actual bouncing between 27 deg btdc and 0.
Before that, the car was runing normal. I even swapped back to my .216 bosch nozzles, i thought it was too much fuel.
Is there any chance that the pump is mechanically 180 deg off? Or a different mechanical adjustment of the cam, because it opens early and closes later?
