I'm in need of a used (preferably) MEFI 3 ECU. The fuel pump relay enable on mine is dead and I don't think anyone "fixes" them that I can find. I may do a MEFI 4 ECU if needed, but would rather not go through the trouble of making the conversion harness. If I find a used MEFI 3 I can reprogram it with my .bin file and I'll be set to go.

Any help is appreciated.

I think i have a couple of them. Condition unknown however.

Give me some contact info and I'll get in touch with you.

Thanks.

you mean in addition to the 5 websites he has listed? He owns mercruiserparts.com, bought plenty of stuff from him, good company to deal with.

I called three of them and couldn't get through..... ordered the housings from Delphi to make a 3 to 4 conversion harness.

I have MEFI 3's they are the 009 units.

Can reflash.

You can also move up to the MEFI 4 but will have to repin the stock harness... not a big deal.

Do you still have these? Please send me an email to [email protected] or call me at 580-761-3414
Thanks,
John
