First.....what fuse is blowing....what does it protect? The short or surge is in that circuit, so start there.
If you are getting a shock from the engine, this is serious. I assume the engine is running? I suspect bad spark plug wires. These are high voltage. Most of the rest of the vehicle is DC, low voltage, and highly unlikely to give you a shock (that you would notice). But a bad spark plug wire, shorting against the engine block, could give you a shock.

You need to identify the circuit in which the fuse is blowing and that the current rating of the fuse is correct for that circuit. You didn't say if your engine actually started, because logically, if the ignition circuit fuse blows, then your engine wouldn't run.
Conversely, to get a shock from the engine (again you didn't say specifically if the shock was from the engine block or a faulty high tension wire) the engine must be running. You would not get a shock from the low voltage circuit of the engine, so it must have come from the high voltage circuit somewhere. In respect of the high voltage circuit, the block of an engine is electrically 'earthed', so with all due respect to another of the answer's authors, you cant get a shock from the block even if a high tension wire is made to jump a gap to the block. Consider this is what is happening all the time across the spark plug gaps inside all of the cylinders, you just don't get to see it.
I'd be looking for a short to earth (the block) in your secondary circuit (high voltage leads) and a clue to doing this is to test each cylinder individually by moving the insulator caps away from the spark plugs and shorting each cylinder in turn (assuming the engine is running) with a screwdriver, making sure it has a good insulating handle!, until you isolate the faulty lead. If it had this fault, your engine would be missing anyway, if one of the cylinders is not firing properly due to a weak or no spark. This is diagnosed by listening to the exhaust note for a distinct popping noise.

have you had your van hooked up to a diagnostic readout tool? most of the time it will tell if there is a problem in the system. also the fuse that blows, is it the right amperage. for example; someone down the line may have put the wrong fuse in. your owners manual should point you in the right direction as far as the proper fuse, unless there have been changes in things like amplifiers and flat screens. as far as being shocked the engine may be experiencing a bad neutral ground from the engine to the frame.

you have a loose ground wire or either a bad connection somewhere...jsut which fuse is it popping...this will help in location of the short to ground.

i could advise that ya do ALL required maintenance first.gasoline filter out,Trans filter out & fluid,Coolant. verify yer air filter out, plugs & wires.replace if needed. Ya might wanna p.c.. up a Haynes instruction manual ( $18 ) that can assist you you by it. solid success !

if you don't know how to trace electrical problems get a mecanic
because it could be almost anything
