There are several things that could cause this problem. If you can't do the testing yourself, you should take it to a reputable shop that specializes in electrical diagnostics. It could be a fuse, a wiring problem, or something in the dash cluster itself. Your Toronado has at least three computers (the IPC, the BCM, and the ECM) as well as a Central Power Supply module. Pinpointing problems is not a simple task.
Check all the fuses. Is it an intermittent problem? Are all the gauges not working? Can you retrieve any error codes?
A common problem with the digital dash cluster is that eventually the capacitors leak, causing display problems.

Gasoline gauge is erratic; does not show true reading


Most likely it's the sender unit inside the gas tank. Here's a quick test to determine if problem is your dash gauge or the sender unit. At the gas tank, unplug the electrical connector and use a jumper wire to ground the gauge sender wire on the car side of connector (not the tank side of connector). With key on the dash gauge should move to full, meaning your dash gauge is good, but the sender inside tank needs replacing. Check with Ford or a ford guy to see if your tank has to be removed from car to access sender unit. Some cars today have access panels to tank under rear seat.

My oil pressure gauge (on the top right of the dashboard) randomly shows the oil pressure going down to zero (check gauge light comes on) and then randomly goes back into the normal range. It happens...


Did you compare what your dash gauge read when it was acting up and compare it to the manual gauge at the same time? I know you said you used the manual gauge and it read fine so if you get a proper reading out of the manual gauge and an improper reading out of the dash gauge then your dash gauge needs addressed.

I have a 1994 ford halfton 5l engin and it seems to be running hot but it dont show on thedash instrument when i come back from a ride say about 10 mile it smells hot


Check the operation of the gauge on the dash by disconnecting the wire from the water temperature sensor (it will have just 1 wire), and then turning the key to ON, without starting. Touch this wire to ground while watching the temp gauge. It should swing to HOT when the wire touches ground, and go back to COLD when the wire is removed from ground. If it works as it should, you need a new sensor. If the gauge does not respond as outlined, the gauge or wiring is faulty.

Electrical Problem with speed gauge, RPM and dash board lignts.


That is a manufacturing defect associated with your instrument cluster. My local dealer replaced my entire instrument cluster for free (truck was out of warranty) when my speedometer showed 100 mph in a parking lot and my oil pressure gauge read 0.
