'165 swap problems

I just wired everything in as the tech article specified for the ecm swap from '870 to '165. I must have done somthing wrong because the MAF Burn-off relay is constantly humming when the battery is connected.

It is not surprissing that the car runs like crap. Where should I start? It seems that the relay is reciving voltage all the time when it shouldn't

Re: '165 swap problems

As a follow up the Maf burnoff relay was removed and reinserted trouble cleared, no humming.

I would suspect dirty contacts that were "cleaned" by removing and reinstalling the relay. The humming was probably due to low coil voltage, not fully pulling in the relay armature.

Re: '165 swap problems

I'm troubleshooting an unrelated issue on my 7730 conversion and I ran across the MAF burnoff relay, long since unplugged for the same reason and forgotten. Once I figured out what the relay was I remembered.
