starting problem

[91yota-sr5]

About a week ago my 1991 4runner wouldn't start. It has a 3.0 with a little over 170k on it. I messed with the terminals, and it started back up. I realized that the terminals were kind of corroded, so I loosened them up, cleaned them and put them back on there. It started and ran fine for a couple of days, and then it just stopped starting. The engine turns over, but it just won't actually start. I replaced both terminals today, and now it's not starting at all. The battery is reading a full charge on the gauge, and all my lights, signals are working fine. I had the alternator and battery checked at the auto parts store a few days ago when it was running, and they said everything is fine. I also inspected all the connections on what I think is the distributor, and they all looked good, except for the main plug in the center of the cap. When I removed it the round metal terminal stayed inside the cap. I pulled it out with pliers, reattached it the wire, and plugged it back in. I don't know the exact term for the wire, or if I reconnected it properly, which might be the problem? I'm not a super savvy mechanic, I have a little know how and some common sense, but I'm worried that this might be beyond me. Any input would be appreciated.

Cleaning and tightening contacts are always a good idea.
Your starter turns over so now you know you have a strong battery. Focus on checking for spark and fuel. Search the forum for that.

Might want to repalce that coil wire. Check your fuses as well, specifically the EFI one

I'd replace the EFI relay, then check fuel and spark. The relay is about $12 from the local dealer, and they generally have it in stock. You might also consider replacing the wires after that.

thanks guys, I read a post about fuel issues and am thinking it might be the fuel pump, I cycled the key in the ignition a few times and it started up after a little hesitation

Don't just blindly replace parts and throw money at the problem; that's the approach of incompetent mechanics who get paid for their guesses, whether it fixes the problem or not. Get a multi-meter and test various points for voltage where Voltage supposes to be, spark plug and ignition coil wires for proper resistance within limits, check for spark, check for fuel flow, etc.
