Check for power between the pump connector and the chassis. The ground wire might be corroded or fatigued. If you're seeing the power for 3 seconds when it should be priming, then the ECU is working properly.

It's possible that the fuse is partially blown, or there is some other problem where the current is getting restricted. If this is the case, you'd see proper voltage if the pump is not connected, but things would go wrong with a load on it.
