1992 Mercury Sable ignition

92 merc, car shut off, I have found modules blown, and changed them out when found, a mechanic friend of mine put his diagnostic box on it before I changed the computer, as it would not give him a reading, have now replaced computer. I have checked for power into pump. Etc. If I by pass the ICM to the fuel pump, I get pressure but no fire. I have replaced the distributor as well, spark plug wires. I have power to one side of the coil but still no fire. The idiot lights come on in the dash, It will turn over, main fuses are ok, no fuses in box under the dash seem to be blown. I know the car is not worth any thing but this is all we have. I know ford products are full of fusible links but I can not find info as to the location. Where can I get a good schematic? Thanks for your help
