ECMI fuse keeps blowing. Wiggle harnesses sometimes starts back up. Usually blows while driving or on key turn.

Hello, that fuse serves several different circuits, about 1/2 dozen. Injectors--ignition module--coil and a few others. That doesn't count faulty wiring or connector somewhere. I'd have to hunt and peck.

have looked at wiring and moved them around but no obvious sign of chafing. If I knew specifically where to look it may help.

Yeah, it is like hunting a needle in a haystack. You might follow the harness from the fuse box, anywhere the harness might come in contact with anything, see if there is a spot that has rubbed through? You might also do an ohms test on the injectors, compare the readings. Plugs and plug wires ok?

Thanks for the help. right now it is working but scared to drive in case it breaks down. Is there any solution to finding solution if it goes on me on the road. Unplugging other fuses etc? Unfortunately I have a 500 mile trip home I have to make next week and where I am there are no mechanics etc.
