'Spout' is the circuit from the PCM to the ignition module. When unplugging the spout connector with the engine running the code 213 will trip inadvertently. You shouldn't see it on a running test with the spout connector in place though. When Ford finally remote-mounted the TFI to the heat sink and...

If you disconnect the spout connector while the engine is running, RPM should drop. Plugging it back in will have the opposite affect. Nothing moves in a TFI-IV distributor.

Re: Fluid leaking from E40D

Most likely the front pump bushing galled, stuck to the torque converter and then spun in the pump housing. It's an E4OD thing. Usually happens under load.

If so, it will need a front pump, and possibly a torque converter. A new/reman pump will have the bushing staked so it can't spin.
