406 1.9td problem
this issue is a weirdy one
just changing back to diesel from veg on this car as new person wants it that way ..
when running diesel we now have a clatter ...as if cold start advance is operating
engine management light is on
well it goes out on start up then comes back on when it does engine starts clattering more
occasionaly twice engine will not rev past 2000 rpm but if u switch off= then straight on again it will rev freely
it has 2 wires going to cold start mechanism under pump
removing feed to them made no difference
it starts easy reasonable amout of power just much more clatter
certainly got me thinking ..
i am told this is ecu sending wrong sigmals to pump
unplugging makes it go tofull advance as theres no change in engine note i reckon she is fully advanced now ...
anyone know how ecu is cojntrolling this is it by voltage
is it just for cold start
tia
