No timing advance on my 93 Ranger?
I just picked up a 93 Ranger 4x4 with a 3.0 V6 in it, it was a bit slow, so I just tuned it up, but was still a dog, so I checked the timing, and the base timing was ok, but it will not advance as the engine revs.
Doing some research, it said something about disconnecting the SPOUT connector to set the timing , then plug it back in after you set it, but I cannot find any such connector on the truck? It also said that the EEC computer part of it controlled the timing, how many brain boxes are on this thing, I was going to pick up a used one and see if it helps. Any ideas on how to make the advance work?

I suspect that if you look at the Ford Ranger Forum that the answer might be found there (http://www.fordrangerforum.com/3-0-vulcan-tech/).
If it were not so late tonight I would do the research on this one.
It comes to mind to look for the MAF (manifold pressure sensor) and for vacuum leaks that could keep this from reading right. If this sensor is not reading right either because of being bad or not getting the right readings the ECM will not perform this function.
Also see if the distributor has centrifugal advance, some times these get stiff and do not work as designed.
