Pull the brown vacuum line from rear of injection pump. This connects to the vacuum shut-off element. If vacuum lines were connected incorrectly, constant vacuum will cause the pump to shut off fuel delivery within a few seconds after engine has started (the amount of time required to build up enough vacuum). If removing line allows engine to run, check the vacuum lines for proper connection and also test the vacuum shut-off switch (device is controlled by ignition key position). Sometimes the shut-off switch can fail open allowing constant vacuum to be applied, thus causing engine to stop running after a few seconds.
