Modern Vespa

NO CARB. 2013 150 lx ie won't start. Getting power but just won't start. It sat about 4 months. New Gas put in but no help. What next anyone please 😩

Is it turning over? Are you getting spark? Is the fuel pump working? Lots that can be looked at, but you need to provide some more details.

It's turning over like it did before but I think it isn't getting fuel to where it needs to be. I need a Diagram or Picture of the inside of the workings because it has No Carburetor and I want to be sure where the Petcock is, fuel and vacuum line.

When was the last time the bike ran, and has anything been changed since then?

Just follow the fuel line from the bottom of the tank to the pump to the injector. The vac line(s) tie into the emissions evap canister. While that can prevent starting, it's likely that it's something else.

Can you hear the fuel pump prime when you turn on the ignition? My guess would be an issue with the pump or something else that's preventing spark.

Same thing happened to my LX 150ie twice when left unused for 6 months plus.

In both cases I replaced the fuel injector and fuel pump/filter assembly.

The plastic hose that connects the fuel pump to the main fuel filter gets brittle and eventually develops leaks that reduces pressure.

Runs and rides like new after that.

like thefakebecky said, when you key it up you should hear the pump prime. it'll be a little subtle dut, dut, dut, dut

if you don't hear that, check your fuses and then check the pump.

if you do hear that, suspect the injector. pull it and hose it out with some brake clean and purge the system of all the bad gas and you should be cooking.

this is all predicated on it having the correct key and not showing an immoblizer code.

once you get it to pop and fart, it's time for a tune up.
