replace mass air flow sensor, won't start

I inherited this truck from my dad and it had an issue with power so I was messing around with the air intake system. I ended up busting the mass air flow sensor in the process. The truck ran before, just no power. I replaced the sensor and started the truck. It actually started right up and I let it idle for a few minutes. I gave it a little gas up to 2500rpm and then let it idle down and put it in reverse. I idled out of the garage and when I applied some gas while it was in reverse it started to die. So I let off the gas and put it in neutral and tried the gas again, it still started to die. I then put it in park and gas one more time and it completely died. Now it won't even start. I let is sit for a few minutes and nothing. I disconnected the battery thinking the computer needed to be reset and nothing. I ended up pushing it back into the garage. I still have the battery disconnected just in case that is the issue.

Does anyone have any ideas what I can look at? The sensor I bought was used from a wrecked 4runner, the guy at the yard said the 4runner was running before they gutted it. it did start up right after I put it in so I figure this is something else. Thanks for any suggestions!
