have you ck'd your ballast resistor? on my 89 d-50 2.6 it's mounted near
the left fender. it's a white ceramic elec. part with a coil wire under
it.if that is burnt into that could be your culprit. also could be
corroded. if new one is required,about 15.00. hope this will help. also i
need a vaccum hose diagram for 89 d-50 2.6 mitsubishi mckiney carb. about
46 hoses. can't find one anywhere. thanks.
