I have the car listed above with a blown motor... I found a 2009 Pontiac Vibe with a compatible 2.4L 2AZ-FE engine. After swapping engines all I get is crank no start. I've checked spark and fuel. Everything looks good. I checked the engine codes in the vin and the scion is a 7... and the vibe is 0... are the engines different in some way? Do I need to have the ECM reprogrammed or replaced? Like I said, both engines are 2AZ-FE. The scion was manual trans, where the vibe is auto but I put the manual transaxle on the new engine so it shouldn't matter right? Only other difference is the year... the scion is a 2006 and the vibe is 2009. Did the engines change between then?

Hollander shows they don't interchange but doesn't really show why. It does show the Matrix and Vibe interchange but only the 09-12 years, nothing earlier. I would suspect that there are either sensor or internal changes. Not uncommon for that. It also shows that the TC engine interchanges from 5/06 up to 2010 but only in the TC, not with other vehicles.
You might be able to find the changes if you go to a place like rock auto and look at the various parts like cams and sensors and see what parts are different. It could be like Chrysler with the 3.7 where they only changed 2 parts inside it that made it, so the engine didn't interchange with the others.

I did a little more research and all I could find is they upped the compression from 9.6:1 to 9.8:1... so do you think the motor from the vibe is a total bust?

Hard to say because they don't say what was changed. On the 3.7 I mentioned they Changed the cam and crank tone rings, so the notches were reversed when they changed the control electronics. Swap those two parts and it works fine in the other years.
I suspect you have a similar issue. I think the block and head is the same and most of the other parts seem to be, but it only takes one part to mess things up. And because you have a GM vehicle and a Toyota, I suspect it's something to make them incompatible so that folks don't connect the two. A lot like all the other companies who want to hide the facts of who really builds what.

Here are some part numbers to look up from the 06 engine:
Crank - 134010H010
intake cam - 1350128040 Exhaust cam - 1350228010

It does look like the scion and vibe crank and camshafts are different part numbers... so do you think if I swap the scion crank and camshafts into the vibe engine it will work? I'm trying to save as much money as possible because I already have way too much invested into it lol. And help would be appreciated.

I would probably look over the parts and see what's different. It could simply be that GM wanted 3X and 18X signals while Toyota wanted 6X and 24X. You could test that if you have access to an O-scope or rig up a test to watch how many notches are showing up from the sensors. If I remember that engine uses a bolt on reluctor wheel (# 19315-0T030) behind the crank pulley. Take a look and see if those are the same between the two. Could do the same with the cams. Might be that you just swap the crank wheel or a cam and are done.

Thank you so much for your help. The pickup for the crank sensor was different pattern and while I was in there, i changed the cams just to be safe. Motor is back in, starts and runs. I really appreciate you taking the time to assist me with my troubleshooting, it helped a lot.

You are welcome. I suspected that GM used their engine controls and Toyota wanted theirs. It's like other "joint ventures" where they work together to develop something but still need to change parts to make repairs harder. Glad you figured it out and got it running.
