Problem With my 91 honda accord ignition.
 

Ok guys i really need some help. SO I bought a speed sensor for my 91 Honda Accord. I put it on turned it on and took it for a drive to make sure it was working fine. The car was running great, however the following day as I turned it on and put it on R the car just turned off. I kept on turning it on and putting it on R and the same thing. I had to wait a bit for it to warm up then I was able to drive. So as Im driving a stepped on the accelerator and the car wasn't accelerating. The rpm needle was going crazy and the car wanted to turn off on me. So finally the following day as I'm coming home from work it turned off on me. I was just able to get home. and since then It hasn't turned on at all. My question is, what can it be? I checked the speed sensor wiring to make sure i connected them right. and I honestly have no idea what it could be. Maybe the module? Can anyone help?
