Your coolant leak sounds like the heater box drain tube, and is most likely caused by a bad heater core. If you can smell coolant inside the car, or if your windows fog easily, it's a leaking heater core. The 93 Vin-T 3.1L engines didn't have the intake gasket issues that plague 94-newer Vin-M and 97-newer Vin-J 3100's. On the fuel filter issue, there is a fuel line repair kit for the fuel filter connection which is a fairly simple repair. If the fuel filter is plugged up, it can cause a fuel flow issue, so get that fixed first before getting into it any further. Most parts are interchangeable from 90-93, on the ECM, make sure the service numbers match, and swap the prom from your original unit into the new one. I would suggest against installing a used ECM (if that's what you were getting at), as they are a high failure part due to being mounted under the hood.
