[70-914nut]

Need help with fule injection for 1.7 1970. cant get the fuel to the engine. tried putting fuel in every line. checked fuel flow to the pump. seems to have a little air past the filter (new) pump is sluggish after rebuilding and cleaning the varnish out. i would think yhay the pump would pull fuel to the bay right? with the engine turning over but not starting the pump runs. i do have some vacuum lines gone but the big main one is there and the distributer line as well. please help. im ordering a new pump because i just dont think it is operating as it should. thanks

Do you know if your FI is energizing the injectors?

You can test this in 2 ways:

First, disconnect the +12V from the ignition coil. Tape the spade up if you think it might hit chassis ground. Removing +12V from the coil will allow you to turn the ignition on and test the FI w/o burning up your points or Pertronix.

With +12V off of the coil, turn ignition to ON and open the intake butterfly.

You should hear the injectors click. This should test if the injectors even operate.

Then remove the distributor. You can take the cap off, that is not needed here. But do keep the FI contacts connected.

With the ignition ON, spin the distributor with your hand. This will simulate the engine running, and the fuel pump should turn on and as you spin the rotor, you should be able to hear the injectors opening and closing.

You can even test for fuel flow by pulling out the injectors and placing them in a jar to see the spray. But you have to keep turning the distributor.
