240 won't fire after removing instrument pod

This is crazy. The car was fine. I was installing the new tach (found through this forum) and messing with the little gears in the odometer (new ones found through the forum as well) and put it all back together. Now it acts as if the plugs aren't getting fire; it turns over beautifully, just won't start. Did I forget something? I can't see it.

Also: the speedometer needle came off very hard and now it doesn't swing freely. I hesitate to press it too hard for fear of breaking something, maybe already have. Anyone have any experience with this problem?

Frustrated,
David

You plugged the tachometer wire that was probably not used before onto one of those blade terminals that was also not used before. The blade terminals that are parallel to each other are for speed output to cruise control. If you have cruise then trace the wire to the cruise control module and then unplug the one that ISN'T that wire.
OR maybe the new tach is bad or wrong wires in wrong place.

Not sure what to say on speedo.

Thanks. I have the wire plugged in to the bottom (vertical) terminal on the tach down at the 6:00 o'clock position. The car wants to start, almost makes it. I've let it sit for a couple of hours just in case. No criuse control, which should simplify things. Should I move the wire to one of the other leads?

Thanks for your advice!

I would try to start with the wire unplugged off tach.
Is this the tach that replaces clock or the small tach that goes into blank to right of cluster?

Yes, this is the tach that replaces the clock. I think the car wasn't starting because I didn't have the full moon and half moon wires plugged into the back of the instrument pod. Anyway it starts and runs fine now. Now my wife tells me she'd like a clock so I'm looking for one of those small ones.

I'm also looking for a cruise control, since I don't have that either. Volvos - like housework - never done. Thanks for your help!
