Question type: Maintenance & Repair

06 Malibu SS Engine swap runs great with 3700m. Then after I turn it off, it will not turn
on till the next day. Before the next day, engine light turns on and data link scanner will
not read check engine light. When I pull the PCM Ignition Fuse from fuse box, check
engine light turns off. Again... the next day my car runs great!

All the basics were checked, tested, and replaced. PCM will not communicate with scanner. Fuel pressure is good, starter and alternator good, fuses and relays good. I am thinking that my PCM is bad... I took it to a CHEVY Dealership and they told me that they needed more time to find the source... I asked if it could be the PCM. They are not sure. Where can I buy a trusted refurbished PCM? They had it for three weeks.. and nothing!

I do not have the vin to the engine swapped motor. Can I still flash with MY VIN? Haven't checked fuel line in conjunction with manifold heat, but will do. Battery was disconnected when working on the swap, thats not to say that complacency didn't settle in after a long frustrating day of swap and accidental short happened. One more thing. Do I have to take my car to CERTIFIED, KNOWLEDGEABLE mechanic while they perform the programming (FLASH)? Also... I have heard of vapor lock.. But of all the forums out there, Your explanation of VAPOR LOCK is now a second nature term for me. THANK YOU!
