Hi all.
Have just joined this group, hopeful someone will be able to provide guidance.

My vehicle is an 04 Atenza Wagon, 5 Speed Manual, 2.3l petrol, with variable cam timing.
was out beating the living death out of it a week ago, (May or may not have been evading police) and I lunched the engine, [snapped the con rod on #4, leaving a few smashed pieces in the sump} i removed the engine from the car but left the g/box in place.
sourced a 2.3 (l3) from an MPV of same year, however was automatic and did not have variable cam timing. {MPV ran and drove fine}, removed MPV engine and swapped manual flywheel and clutch onto it, then installed into my atenza, little fiddling and jigging but i have now got the motor and box completely assembled and bolted in as the origional was, used all existing wiring from atenza, even swapped MAP, CXP, TPS, cam angle sensor, coil pack, EGR system to the origional atenza parts, all plugs in fine, turn key, fuel pump primes, crank engine and it fires once, then nothing. im now at at loss. any help would be greatly appreciated. am based in manawatu new zealand

Did you use the ECU from the Atenza?
I’m not sure how the VVT works on your year/model but I’m assuming the ECU has something to do with it. If you put a non-VVT engine in with a computer that’s trying to control it thats most likely gonna be an issue.

Yes, I did use the vvt pcm/ecu. Had wondered if that may have been an issue, so I have since installed the vvt intake cam and actuator solenoid onto the new engine, reset engine timing etc, no change. My local dealership suggested that I would need the complete vvt engine, however there is very little difference that I can see other than the variable intake cam and the actuator.

Problem solved. Original engine had variable intake cam timing, replacement didn’t. Swap cams and vvt actuator, set timing. Fires up instantly. *why would Mazda not have keyways or something more than just friction to make things more user friendly). As for the “sst” specialist tool to hold cams. The right thickness piece of angle iron is perfect.
