Hey guys, new here. My buddy and I are working on a 72 1.7L and it's only running on 1 and 3. Cleaned and checked the trigger points, still no dice. Now, when you unplug the connector for the trigger points, it runs on all 4, for about 3 seconds til it starves of fuel. Input?

Turn the plug on the distributor around and see if it runs on 2&4. If it does, you have a trigger point problem. Also if it does, your injector plugs are switched.
One and four fire together. So do two and three. |

QUOTE(The Cabinetmaker @ Sep 20 2016, 02:13 PM)  Turn the plug on the distributor around and see if it runs on 2&4. If it does, you have a trigger point problem.

Cabinetmaker is right about the injection grouping, it's 1 & 4 and 2 & 3. If you're seeing both cylinders 1 and 3 working, then both injection groups from the ECU are working, and I think this also implies that your trigger contact points are working, too. Your issue does not appear to be the ECU or the TC's, leaving the harness, the injectors, and the grounds to check. |
