Ford mechanics - Timing question

Helping friends son get f150 with 4.9 back on road. He had the timing 180 out. We did a static timing and it fired right up. Tried to do the timing with my timing light. When we disconnect the "spout connector" there is no change in the timing mark or engine rpm. If the PCM and the wiring are good shouldn't we see some kind of change? Not familiar with this engine but I think we have other issues. Thanks for any help.

    timing light?

    I thought those went out with bias ply tires?

    haven't worked on cars in years

    thought it was all done on a computer now

    I still own one. But like you, I was not aware they were used any more.

    When your SPOUT Jumper is out your computer is in Closed Loop. With the SPOUT Jumper in, your computer will try to go into Open Loop. What I am trying to say is that when the SPOUT is OUT, you've taken computer control away of timing and mixture.

    replace your tfi module

    The TFI ignition module controls the spark on your car's engine, but when it fails it can cause multiple problems. Things got so bad with TFI failures that there was a class action lawsuit in the early 2000s. As ominous as this sounds, take heart in knowing that the worst of the issue is resolved by now. Still, the TFI can fail just like any other electrical part. Here is important information that you need to know about the Ford TFI module.

    What is a TFI module?

    TFI stands for Thick Film Ignition. The module itself consists of some solid state electronic components suspended in a thick, clear electrolytic film, hence the name TFI.

    What is the TFI module's function?

    The TFI module (also known as a spark module) is necessary to control the spark output of the ignition system via the EEC (electronic engine control) computer. A signal from the TFI module is sent to the EEC and the computer then controls the spark to the spark plugs. It is a very necessary and vital component of the entire EEC-IV engine management system.

    Where is the TFI module located?

    Depending upon the engine configuration, the module is usually found on the distributor itself, on the front of the motor:


    or you could just spit in the back and whomp on it

    Thanks for all the replies. I am not sure what year the motor is and this whole truck is a Frankenstien. It has had a lot of wires cut and spliced. I hate working on something like this because you can never tell what was done but I am trying to help a friends young son out. I have read just about everything on the net about the spout circuit. I guess I can assume that it is not working as it is supposed to. I set the timing with the spout connector out and the timing does not change when plugged back in. I believe when you plug it back in the computer takes over and should advance the timing by 20 degrees or so. I guess I have to trace out the wires and see what I can find. The TFI module has already been changed.
