2009 Aveo put in new (used) engine. It runs 5 seconds and dies. Now what?

Hey Waverider, did you ever figure out a solution to your problem?

[WaveRider]

No, I didn't. I ended up putting the original engine back and selling the car. I bought something more tolerant to modifications. Sorry I couldn't help

SOLVED

So, know this is a very old thread, but I thought I would update because I finally know what the problem was. I sold the car to someone else almost a year ago, and he just messaged me that the car is running fine now.

The guy that sold the used engine to me said it was pulled from a 2009. Apparently the new owner checked the engine number, and found out that it was pulled from a 2010. So he bought a used ECU from a 2010, stuck it in, and the car now runs like a top. I had tried 3 different 2009 ECU's with no luck.

I can only surmise that Chevy changed the reluctor ring, or the timing relationship between the crank and the cams. Whatever, if you swap engines, make sure to get the proper year ECU.

Bye all.

Even though you didn't finish the swap did the 1.8 bolt and wire right in with no fabrication?

That's right if you put a 2010-2011 in a 2009 you will have to swap the ECM or have it flashed the cams are diffrent rods crank and block head VVT cam gears/sprockets were diffrent as I have 2009 with a 2010 and a 2011 ECM if you put a 2009 in a 2010-2011 you would have to do the same
