Re: EEC fuse: 1992 ford explorer
Sounds like you have a bad relay that is shorted out or you might have a bad fuel injector shorting out fossible fuel pump wireing short do some probing aroun with the multi meter try to find direct short , use the process of elimination .
now let me see does your truck start up and run then fuse blows? is the fuse the correct amperage check your owners manual to see how long does it run before blowing fuse ? when its running is it running smooth while is running?

What your Explorer has is actually called the EEC-IV. It is sort of like an ECU. The EEC stands for "Electronic Engine Controls". Your EEC-IV Does this:
Powertrain Control Module (PCM)
Throttle Position (TP) sensor
Mass Air Flow (MAF) sensor
Intake Air Temperature (IAT) sensor
Idle Air Control (IAC) valve
Engine Coolant Temperature (ECT) sensor
Heated Oxygen Sensor (HO2S)
Camshaft Position (CMP) sensor
Knock Sensor (KS)
Vehicle Speed Sensor (VSS)
Crankshaft Position (CKP) sensor
The EEC microcomputer circuit processes the input signals and produces output control signals to the fuel injectors to regulate fuel discharged to the injectors. It also adjusts ignition spark timing to provide the best balance between driveability and economy, and controls the IAC valve to maintain the proper idle speed. The EEC is located in the engine compartment. Post your engine size and I can tell you where it's at.
There are 3 relays mounted below the fuse box . The green I believe is fuel pump relay and the brown is EEC. The third relay is for the A/C WOT.
It is possible the wiring is shorted, check there, it is also possible you have a bad fuel pump.
Please let me know what you find.
Try a new relay first. This may not be good news if that does not work. If you can find the EEC (computer) and unplug it, then replace the fuse-if it blows you have another cheaper part on the circuit thats bad.
If the fuse does not blow, then the EEC must be shorted.
If you have to replace the EEC you may find a kindly dealer with a cash-for-clunker sitting there to violate. Salvage yards have them, Ebay sells them. I have seen them at swap meets for $20. They are a high price part even rebuilt at Dealers or autoparts stores.
