1993 Ford Taurus 6 cyl Front Wheel Drive Automatic 156000 miles

My car abruptly won't start. It is acting weird though. Both the fuel pump and the electric cooling fan also stays on in the ingnition position and won't shut off. I have let the car stay like that for a few minutes hoping that it might start, but it won't. I have checked the fuses and the fuel inertia cutoff switch. I recently did a tune up on it also replacing the diributer cap, rotor, plugs, wires, and air filter. I was told that the fuel pump relay might be stuck, but I'm not sure where it is at on this car and the Haynes manual doesn't mention it. I am wondering what would make these both stay on indefinately and how to go about further troubleshooting. I have thought about the possibility of the fuel filter being clogged along with the fuel pump impeller being worn out and just spinning and not really pumping anything. I really didn't notice any loss of performance before this happened though. I am at a loss of where to go from here and I don't want to go and break into systems without knowing what the problem is.

Do you
have the same problem?

Lets knock out the fuel pump-The fuel pump relay is located in the engine bay center of firewall-if the switch side of the relay is sticking closed it will cause your problem to continue to run-Lets check the fuel pressure to rule out the fuel pump. Also might want to check for injection pulses.

Also the fuel pump relay controls power to EDF/HEDF Relays which has something to with the cooling fans.
