fuel injection issue, trigger points? Options

[luskesq]

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?

All stock 1.7 have the trigger points in the distributor. The way to test them is have someone turn over the engine while you measure continuity between the center and either of the the outer pins of the distributor. The circuit should open and close once per rev of the distributor rotor. One side of the trigger will fire injectors 1 & 4, the other 2 & 3. As the triggers wear, the slider blocks wear out - the circuit fails to open, and the ecu doesn't receive the signal to fire the injectors.The function of the trigger points is unrelated to the tps. good luck.

Buried under the vacum hose to the advance is a 3 wire plug into a receptcle on the side of the dist. That piece goes into the dist but I don't see screws holding it in place. It is lower than the point plate so I don't see how I can either service it or replace it without pulling the plate (with points) off? Am I missing something (likely)? Thank you again for the help.
