After my 01 Sebring engine died on me, my mechanic found another 2.7L engine that came out of an 04 Sebring. I already installed all of the 04 sensors it needs. My car still isn't turning over. Do i need a new ECU also? If so, which one? and how do i find out? The place i got my engine from can't find the ECU that was in the car with the engine.

Thanks!

 

the cam shaft town wheel will need to be replaced with the old one from your engine
Search this site U are not the first nore will be the last one to do this .

 

I have tried the original one and the new one. only one cylinder is firing.

 

so u took apart the timing chain 2x already ?
