Is the battery dead, they do just go open circuit with not warning, very common in compact batteries. Check the voltage at the battery.

What is a Piaggio MP3 300?

Great question! But do you really think someone can go thru the entire process of an engine rebuild online, in text, with someone we cannot bi-directionally communicate with in real time, unable to see what you are seeing and be able to pull that off effectively? It's admirable you want to take on the project, but you need someone with knowledge that has a physical presence where you are to assist you in this endeavor.

Test the wires going to the sender by using a test light on them with ignition on. If the gauge moves then the wiring is probably OK. The senders are touchy and may have burned out the thin wire coil that runs through them. Wiggle it- see if the gauge moves. The senders are a sealed unit, so it usually requires replacing when defective. Be careful with electricity around fuel or an open gas tank.

hi there, I gathering now when the batteries connected correctly you get no power once the ignition is switch on yes? if that's the case then you've blown the 30amp main fuse which can be found by following the live wire (red one) from the battery to the starter relay. Change the fuse, all will be well again.

i can get them but if it has an immobiliser on it the new keys will need a code to be put onto the chip inside them to work.you should have a code card that came with the bike from new ?its white and blue.

How to start your scooter after weeks of sitting

I cannot find a free download but Haynes have one which you can buy on eBay http://www.haynes.com/repairmanuals/piaggio/sfera%2080

faulty battery connection or duff battery

Check the line from the tank to the carbs, disconnect where it goes into the carb and see if you have fuel flow. If nothing then try blowing back up the line to the tank to see if it is blocked as stale/old fuel can go off and cause a blockage in pipes and filters. The following may not be applicable to your machine, but my bike's fuel tap is operated by vacuum and needs the engine running to open the tap up and allow fuel to flow. There is usually enough fuel in the carbs to fire the bike up and open the tap, but it does have a "priming" position just in case they are dry.

did it slow down the last time you rode it ?and were you giving it a thrashing?if so you probably had a partial seizure and the piston rings will be stuck in the piston which lowers the compression and stops it starting again.

If you can't replicate the fault by wiggling, my next concern would be that it might be getting pinched. This might cause a grounding fault to the chassis if any bit of the wire is exposed. However, sometimes cable breaks are internal and the wires short out without you seeing. I would think you'be be blowing a fuse if this were the case. Just in case, rule that problem out. If you have a multimeter unplug one side of the headlight wire and put a lead on each wire. Move the handlebars and see if at any point it drops to 0 ohms. This would rule out any of the conditions above (short to chassis or to wire). The next step is to unplug both sides of the cable. I'm not sure of the wiring diagram for the scooter, but if you can't unplug the other side and it goes straight to the fuse, remove the fuse. Essentially what I am asking you to do is make a continuity check. The positive lead on one side, use the multimeter to check the length of the cable. Here you are looking for 0 ohms per wire. Again move the handlebar and now see if the resistance jumps up to an "open" state (anything other than 0). If you find a wiring diagram let me know, I'll take a look it at for you.
