1994 ranger 4x2 3.0 v6
I replaced my ignition key switch cylinder and my ignition switch today. My steering column is in bad shape from previous owners. Alot of broken pieces and such. My truck ran great with a little slippage of ignition. So I replaced. Now truck will crank but no spark...? I can hear fuel pump and I previously had no problems. Is there a sensor inside the column or around the key that could be the culprit? The key cylinder cover is kinda busted up a bit but I can get it to engage and crank engine but no spark.

You didn't post the year of your truck, but sounds like you have a PATS issue. You say you replaced the key switch cylinder (and keys, I presume). The keys have a chip inside that have to be added to the PATS (Passive Anti-Theft System). This is a theft deterrent. There are ways you can add the new keys to the PATS yourself, but in this case, most likely will be a dealer thing since the new keys have a different mechanical cut. Put the old lock cylinder back in and most likely the truck will start.

You are correct, PATS didn't exist in 1994, so that isn't your problem. I went back and re-read your post. Right there... first line, you stated 1994 Ranger. Need more coffee!
Anyway, I would go back to the ignition switch and ensure the connector is fully seated. Not sure about 1994, but most of those switches have slotted mounting holes so you can adjust. If so, ensure it is adjusted properly. Check all fuses in case you popped one while changing the switch. If all is okay, put the old switch back on and see if it will start. I have seen DOA switches before, so it is possible you got a dud.
I can get it to crank the engine with new key cylinder. There is a chance it is not seated correctly. So is there a electrical connection tied to that that won't let engine spark? All my fuses and relays are good.
The lock cylinder (the key part) has no electrical connection that would kill the spark. The switch (farther down on the column) is the one that allows the truck to crank and/or start & run.
Okay, here is something to look at. This is for a 1996 Ranger (oldest service manual I have). Ignition tamper sensor. See if yours has this and that it is installed/connected properly.
