'71 1.7 with original FI, won't start.
  • Fuel is circulating; although, fuel pressure has not been tested.
  • I have spark.
  • Pulled injector and placed in glass jar - no squirt.
  • Power supply relay (supplies power to ECU?) checked out good.

Distributor doesn't appear to have injector trigger points (i have only one wire coming off the distributor).

What else should I check? (IMG:style_emoticons/default/confused24.gif)

Is this no-start a new issue or has the engine never ran for you before?

Are you sure the dizzy doesn't have trigger points? How about the connector on the dizzy for the trigger points?

Where's the connector for the trigger points? Have you located that on the engine?

Without the trigger points you will have no fuel in the injectors.

It was running before changing out all the fuel lines. Maybe i knocked something loose.

I only assumed no trigger points since i saw only one wire coming off the distributor.

Should be a connector coming off the base of the dizzy. If not, find the pigtail with 3 or 4 wires that connects to it and reconnect it.

The connector is usually on the backside of the dizzy and comes from the FI harness......gotta stick your head in there.

You got the supply and return lines crossed perhaps.

Perhaps that. Also check all of the electrical plugs in the engine bay. It's not that hard to bump one and disconnect it. Every once in a while, you may be able to move it enough to disconnect the connector electrically, but not enough for the plug to be flopping around loose...
