Wont start

Just fixed the exhaust bolt and manifold, replaced the fuel injectors but now it won't start sounds like it's gonna start but it won't. Would having the vacuum lines hooked up wrong be the problem? I'm kinda stumped? The battery seems a little low but I'm so frustrated!!!! Can anyone help??

When you turn the key on and the electronics turn on does the check engine light and gear shift light come on?

Hooking up the vacuum lines wrong will definetly cause it not to start. Check the codes and double check the connections. Look at the crank sensor connector at the rear of the engine on the bell housing. Check for codes. Clear them by disconnecting the battery for a long 10 count and recheck after trying to start it.
