[Hempo]

Had my heads polished and fixed after i blew a valve last summer. And now when all is put together and i try to start the engine cranks but wont start. I get the code P1604 Startability Malfunction and i've felt that the headers are warm only the ones coming from cylinder 2-3. 1 and 4 are cold..

I've checked so the sparkplugs "spark" and they are not dry.

Anyone have any ideas?

Sorry for bad english.
