switched pin on vss, now I get static numbers. A value will show up in each field, then nothing changes, moving or not, running or not. After switching back vss, what might I change to fix 'showing speed at standstill'?

Questions on the custom (first) screen:

How is GH (Gallons per Hour) doing? Is it relative to load & rpm?

What color wire did you tap for speed?

when moving is S look about right?
what range of values does S (speed) read when sitting still?

swapped back, now tapping light green wire off vss(other wire is dark red). GH at 6.5 non-responsive to load or rpm. All other fields read 0. Occasionally bumps back to intro screen. Definite wiring issues, it seems. Is telephone wire suitable, or maybe too fine for application?

telephone wire is fine.

Vss should be connected to yellow wire with green stripe by the ECU and injector should be connected to a yellow wire with black stripe, according to an old haynes book I looked at.

Tapping at vss (easier to find than ECU) Now getting no signal for travel. Also, GH abnormally high (5.4 at idle) but declines with increase in engine speed.

So if I gather this correctly, you are using the wrong colored wire for the vss (which should not be easier to find as it is in the dash)?!? Reminds me of a joke I once heard

There were two guys under a streetlight.
Guy A: [looking around] "I lost my keys".
Guy B: "Where did you lose them?"
Guy A: "Over there."
Guy B: "Why are you looking over here?"
Guy A: "Because the light is better here."

Maybe I'm missing something here? The wire should be yellow with a green stripe for vss. I do not know what you are tapping into that is light green. We will cover the injector later once we get distance working I recon. But you gotta meet me part way here.

I just checked Mitchel and the 1994 model also uses a yellow wire with green stripe.

Sorry, being more familiar underhood than under dash, I went for vss at trans, as well as FI at TB. Will dig into dash 2moro, and let you know how things go from there. Thanx for your patience and assistance.

There should not be a vss at the trans IIRC. I don't know about the 94, but the ECU on the 98 metro was real easy to get to, just emptied out the glove box and removed it (or just squeeze in the sides and flop it forward if it is a warm day). No crawling on my back or anything.

I beg to differ. The ECU has to get that info from somewhere. The vehicle speed sensor is on the trans, measuring revolutions of output shaft. Nonetheless, if I can acquire the correct data at the ECU, then it's there I shall go.
