check the fuel cut out switch which is usually located in the pass rear of car behind the plastic cover.

have you tried to go to a junk yard or to a ford probe forum? I had a 89 Ford Probe GT and had the same issues.

ran it without oil stoped shut it off now it wont start it cranks all day but dont start

goes alternator crank ac and ideler pulley

for the 1993 probe i could only find a 2.5 V6. there are two banks of cylinders, odd and even. in other words as you stand in front of the vehicle the odd bank is toward the firewall, the even bank is closest to you.
the number one cylinder is on the passenger side toward the firewall and firing order is 1-2-3-4-5-6. hope that helps

maybe a bad horn relay.

Section 18-01: Wiring and Circuit Protection 1996 Probe Workshop Manual
REMOVAL AND INSTALLATION Relays The following illustrations show the locations of the various relays on the vehicle.

The Location of the Starter Relay, Main Relay, Circuit (Fuel Pump) Relay, Turn Signal Lamp Relay, Horn Relay, Daytime Running Lamp (DRL) Relay (Canada Only), A/C Relay, Headlamp Relay, and Fog Lamp Relay

1993 is a split year, if you have charging ports are a little bigger than the size of a tire valve stem then u have R12, if they are big then you have R134, most all Ford in 93 use R12. In the picture are adapters for a retrofit to R134, these screw on an R12 port, note the large cap R134 cap on the end of the adapter.

change the idle air control valve

The horn Button at the steering wheel is simply a switch. It grounds out when pushed causing the circuit to close, routing it though the actual  horn under the hood which is sitting there waiting to activate.
