Question about Cars & Trucks
There is excessive current draw in the ecm for this to happen. I suspect that the ecm has an internal short. If you can get it checked that would be the way to go. If by chance you have had a jump start prior to this then it will be the ecm unit.

There is obviously a short circuit somewhere. Best solution, take vehicle to nearest Hyundai Service Center, pay diagnostic fee. They will give you an estimate of repairs (parts, labor, tax, time-frame, etc.). This way you'll find out EXACTLY what the problem is and what's required to fix it.

SOURCE: ecm fuse keeps blowing
just fixed this problem, change your fuel pump module, fuel sending unit shorts out on fuel level swing arm blue wire... unfortinately you must replace it as unit because of the design, fuel pump and tank guage fuel level sending unit are a one peice item, fuel tank has to come out to change unit, about a $ 700.00 repair too... fuel pump module runs about 350 to 700 $ depending on aftermarket or factory, try to find one with a lifetime warranty even if it is $ 50.00 more worth it..labor is about $ 250 to $ 400 depending on shop labor rate... definate problem though I ahve no doubt, common problem on GM... please rate my help, thanks...

Check the four wheel drive actuator on the front axel. It's on the front right side of the front differential housing. It's round with a big hex on it where you would put a wrench, I think it's 1-1/4". Anyway, follow the wires there's a plug about 6 inches away, unhook the wires going to the actuator. Now see if it still blows the fuse, if the fuse don't blow the actuator is the problem. It just scerws out and the new one screws in and hook up the wires. This is a fairly common problem with those trucks. On the early K series GM had the four wheel drive and the heater fan on the same circuit. The actuator would go bad and blow the fuse so now your stuck in the snow with no heat. I think GM changed that in the later years.
