No real answer I'm afraid, but it looks like the EDU relay is closed by the ECM. So I'd start with unplugging the ECM and checking for corrosion at the connections. Then you'll have to check the proper pin out of the ECM and see if it's hot when it shouldn't be. ECMs fail in strange ways. It wouldn't hurt to check the FICM ground to the block, but no ground SHOULD mean no relay closure. Maybe. Also, since you were clever enough to install it, you can probably check the associated wires for chafing. You could have a short to the edu relay wire.

Hope it helps,

Roswell

I guess my post got eaten.

I can't get you what's acceptable. That's a personal choice. Bypassing the ECM could lead to a situation where the FICM continues to pump fuel out a broken pipe after a collision.

I would find the actual problem instead of a quick fix. My dad would bypass the EDU relay. Shooter's choice.
