Hello Everyone,
I am trying to revive a 73 2.0 from a long period of rest (5 years). I am having some troubles and have search till I can't see straight. I am in the process of trouble shooting but have one question (for now):
I read that I should have 20 clicks from my injectors if I press the accelerator pedal to the floor slowly before starting.
Should all 4 injectors click? Right now only injectors 1 and 4 click, 2 and 3 do nothing. BUT, if I swap the wires from 1 to 2 and from 3 to 4 I get the oposite. 2 clicks and 3 clicks but not 1 and 4.
Is this normal?
73 2.0 Stock D-Jet FI.
I think they all should click since the clicks when opening the throttle is equivalent to the carb acceleration pump. Sounds like one of your injector bank drivers is not working.
2 injectors fire together on the FI.
Given the fact that the action changes when you swap the harness, I'd suggest you go thought and clean and reseat all the case grounds first as you might have an issue there, PLUS D-Jet is picky about grounds so it is good thing to get out of the way.
Good luck
Check your connection at the distributor for the trigger points. Use a multi meter to check if both outer pins of the trigger point connection have continuity with the middle pin.
No, only the set of injectors that is being 'activated' by the trigger points. I went through that pretty recently and learned.
If you rotate the engine (and thereby the trigger points) a bit you should switch to the other bank.
That makes sense. I will rotate the engine and check again, then clean the grounds and check the dizzy. I am making a list for the weekend. I was almost sure my harness was bad. I printed off Paul Anders D-Jet test pages and will slowly start to look for my problems.
Thanks everyone for your help.
The condition following the swapping of 1+4/2+3 indicates a trigger point issue.
FI ground issues are 1+2/3+4
No.
FI grounds tied together are 1+2/3+4. So if 1+2 or 3+4 are not working check their common ground point.
Trigger points control groups 1+4/2+3.
