Looks like that is listed as Electronic Engine Controls. 20A* (Gasoline only) PCM, Fuel Pump Relay Coil, Mass Air Flow Sensor, Fuel Injectors The best I can tell you is you might have a short in one of the components listed above, or somewhere between the fuse box and the PCM in the wiring harness I'll leave you with some wiring diagrams, here's the first one. Start with finding fuse 5 toward the top right, ill add more diagrams so you can trace the circuit


Here is the next


The third...


And final...

thanks a lot that schematics saves my garage
