For the first time in 27 years of ownership my Mustang failed to start, cranks but the fuel pump never energizes. After doing some diagnosis and testing it appears that the EEC (A9L) is not sending a Ground Signal to the Fuel Pump Relay. Was wondering where everyone sends out their EEC's to be refurbished and if happy with the results, thanks!

Just to finish this Thread up, got the ECU back this morning. The fuel pump energized immediately upon turning the key so knew everything was good to go, car runs great again!

Those guys have shown to have a really good track record.

Here's a funny story:

We found out about them because somebody came to complain about his experience.

One of the people from the company contacted SN to have their posts removed. I declined stating that, that is not what we do here and that he was free to post their rebuttal instead.

He did. Since then we've had maybe a dozen folks send EECs to these guys and to date, they've all been really happy.

Funny how things work out sometimes.
