1988S4 No Start after Pod Removal
Is it possible to mix up the connections on the back of the pod, and if so would it cause a no start? Tach doesn't move at all.

You can leave the pod on the workbench, with all of the connections off and the car will start. The only thing that won't happen is that the alternator won't charge unless you rev the engine over about 4K.

Thanks Greg, but not the same situation. If it's possible to mix the plugs is the real question. If it is I can imagine it connecting a ground wrong somewhere.

There have been threads mentioning the tach interfering with the CPS signal, causing a no-start. See one mention here.

Will the car start if you disconnect the pod connections?

A couple more threads:

It may be possible that mixed up connections at the pod cause the same result.

disconnect the pod and start the engine if it starts then you had one of the connectors in the wrong position otherwise get out the WD and trace the wire colors to the respective connectors

I disconnected the pod. Still no start. No spark. Fuel in the rails, but not on the plugs.
Exorcised the after market alarm. Since it cranks I don't think that was the problem though.

Car will crank with alarm armed/activated.
Alarm disables fuel pump and ignition so that it won't start, but it will crank.
At least that's my understanding of it. If I'm wrong, someone will surely correct me (and then I'll know the right info).

I provided that information, so you would remove the dash connections and try to start it.
Looks like you tried that. Not the dash.

Well, it wasn't the crank position sensor. Also you cannot plug the instrument pod in wrong, so that's not it either.
Oddly Saturday morning I gave it a shot and it actually started, but was very rough. I shut it off, and it never has fired again.
Battery is well charged and new, so strong cranking.
