So I just installed a throttle body spacer and gaskets. Car turned over once then died and now I can't get it to start up again. Any suggestions? Please help, Quadruple checked every connection and everything seems to be connected

 

remove throttle body spacer.

 

I'd like to see a "throttle body spacer gone right" post
Post your exact installation steps and it shouldn't be too hard to figure out what the problem is. A TBS won't help your engine but it won't hurt it. It's probably something very minor you overlooked unless you disconnected the battery and reconnected it backwards.

 

did you plug back all the sensor?
