Have a '70 1.7 that I picked up that hasn't been run in years. Gone through ignition, points, plugs, timing and it runs . . . badly. Discovered when running that I can pull the ignition wires to 1 & 2 and it runs the same. No injector clicking with key on and opening the throttle switch on 1 or 2. 3 & 4 click. Could the problem be the trigger points and do all stock 1070 1.7's have trigger points?

An easy test is to hook up a meter to the injector plug to see if the ICU is sending a signal to the injectors. Plug has two contacts, one is ground. So check that the ground is good, then put the meter to the other connection and turn over the engine and see if the voltage gets to the injector. That way you are checking that the ground is good also from the injector to the rear junction for the inj. ground wires.
