91 E150 5.0 - timing and SPOUT issues
On a 5.0L E150, is the SPOUT connector near the passenger fender? I assume I've identified it correctly.
I tried to set the timing on my dad's van and got no change in timing when the SPOUT was disconnected. Is this a common problem? I've never seen the SPOUT just flat-out not work.

I've just run into the same problem with my F-150 5.0L. And am also wondering the same. Is it a common problem to see no change in idle or timing when the spout is disconnected? If so, can you just cut the "spout" off, and use butt connectors to function for replacement. If it's not an actual problem with the connector, then where might it be?

The SPOUT (SPark OUT) is a pink wire (Y/LG before '90) that sends the spark timing advance signal from the EEC to the ignition module. There's a shorting plug in it near the ignition module that's used to disconnect it so the base timing can be set, similarly to disconnecting the vacuum advance on carb engines. On '92-96 trucks, the SPOUT connector is within ~2" of the ignition module on the L inner fender, taped into the wiring harness. You can identify it by the 2 Pink wires going into it on the back side, and no other wires. The shorting plug is grey.

shouldn't you expect to "see" some change in idle and/or actual timing once the plug is removed? My experiences in the past tell me yes, but now when I remove the plug no change occurs. I'm trying to set my timing, but am unsure if it's actually the base timing I'm setting.

Mine is a 91 E150 - I found a plug just like what I'm used to seeing in Mustangs on the passenger fender well. Unplugging it produced no change at all in the initial timing or apparent idle speed. Must be broken. Shorting out between the wires didn't do much good either.
So, I'm left wondering where the open circuit might be.

You'll only see a change if the EEC was advancing it before you pulled it. Read the emissions sticker for the correct timing procedure.

I have always seen an increase in the initial timing when you replace the SPOUT connector.
