Hello, I bought a Honda off a friend as a project it had a cracked block, I swapped the block from a local junkyard and now I am having trouble starting it.

To further explain after swapping it the engine started I let idle for a bit and then turned it off ( it was over heating, changed the thermostate) , 5mins later I went to start it again I would get weird rpm spikes then the engine dies while at 2000 rpm.

Noticed the key sign showing up when the engine dies, but the key is the one that came with. the car and i did not swap the ECM and it does lock and unlock the vehicle if it was an immobilizer issue the car wouldnt start at all..?

Any input would be appreciated I tried almost everything I dont want to just sell it to a junk yard I encourage any help. thank you in advance.

Did you ever get this resolved...? runiing into something similar
with an engine replacement( cracked block) not reving but just shuts off after 15 min
cranks a little to much and then starts and runs
im wondering if it needs a relearn
any help would be appreciated
