Engine size?

The onyy commom share on the fuses is the VCM/pcm.

If the only one blowing now is the EMCB?
It feeds fuel pump and VCM.

If only blowing when you hit gas may be the answer to problem.

Try easy down on gas and then hit it hard in gear or out of gear and in drive or reverse..
I would wiggle wiring and look for a short.
When giving it gas it may be moving the wiring and rocking the engine.
Got any bad engine mounts or transmission mounts?

VCM/PCM = engine and transmission control computer

great so it could be 1- the fuel pump, 2- the comupter, 3- faulty wireing, 4- bad sensors?

Where do you get bad fuel pump or 4 sensors?
If it is blowing fuse you have something shorted.

If you would give us more info and details some one may be able to help you.
Good Luck

sensors and pumps are electrical when they go bad they become a short

Not always
Almost Everything on it is electrical.
But only certain things on certain fuse circuits.
