intake manifold

I just swapped out the motor from my 99 montana with a 00 engine. Here's the problem the new engine came with the injectors that won't work with the 99 because of wiring issues, so I used the ones from the 99 and now it is pissing fuel out of everywhere. I've replaced the o'rings but I'm not sure these injectors are really seating. Could it be that the manifolds are different and will only accept injectors for a 00 ?

sounds like thats what is happening

Agreed, you should look up the part #'S on each engine, You will problly see the injectors are differant. put in right in ones and change your connectors on wires..
