Engine swap not starting
hello. I have a 2013 Abarth and piston #2 blew pieces and keeled the engine. Got a replacement 2014 Abarth engine. Pulled of my harness and bits and swapped them onto the block. I can’t get it to start. I have power at the relay but signal to the solenoid wire. I bench tested the starter and it works. I even changed out the starter to the 2014 style with a separate solenoid connection. No dice. Anyone ever have something similar?

Re: Engine swap not starting
No idea. If you used you car's original harness and starter then it should have worked.

Re: Engine swap not starting
I've not heard of that before. So the starter plays possum when it's connected to the cars harness? Is it possible that something got pinched in the harness when you transferred it?

Re: Engine swap not starting
Did you use the harness from the new engine or old engine? I’m fairly certain the crank position sensor changed sides in 2014, which the old harness probably won’t reach, I don’t think the car would turnover without that signal.
It did switch. You actually want to use your OLD harness if the sensor moved position. You change the crank sensor from your old long block to the new one in that case. Prior to sometime around 2013-2014 there was a sensor on the front crank. Afterward the sensor is behind the flywheel on the back. You want to stay with the one that your car had originally, even if it means having to change crank pulley or pull the flywheel to add the rear sensor.

Re: Engine swap not starting
I used my 2013 harness on the 2014 Block. I did remove my crank Position sensor from the 2013 Block to the 2014 block and plugged it to my 2013 harness. I did not swap pullys as they both look identical, I will try that this weekend. I know a bad Crank sensor will not allow a start, but the starter should still crank.Romanoaf wrote: ↑Mon Jul 20, 2020 2:18 pm Did you use the harness from the new engine or old engine?

I also made sure nothing got pinched but i am pulling the block out again this weekend to make sure.
Thanks

Oh man that’s the worst! Lol. That has happened to me where you miss one thing and you rack your brain trying to figure it out. Glad it was simple!
