The last couple of days my LX 150 will not start after it has been ridden for a while. The fuel pump no longer comes on when I turn the key until the engine has cooled down. This is the first time I have had a problem with it. I bought it new for my SO in July of 2010. She doesn't ride it and I have taken it over. It only has 2,400 miles on it.

This is the odd part...

I have read there was a recall on the fuel pump for this particular model that came out around 2015. (Don't remember ever getting a notice)

I called Piaggio yesterday to verify this and they said yes, it did affect this particular Vespa. However, they told me the fuel pump was replaced in 2012 as part of the recall and submitted by the dealer for payment.

I am the only one who has taken care of the maintenance and only brought the Vespa to the dealer for the 600 mile service. I waited at the dealer while they did this service. They definitely did not replace the fuel pump at that time. They just changed the fluids and other items required for the first service.

I don't have any idea how the fuel pump recall got submitted to Piaggio.

Anyway, that dealer is no longer in business. Now I'm stuck with needing a new fuel pump installed at about $500 parts and labor.

I'm still scratching my head over this whole thing.

If that is anything like the 250, you can buy the pump only for around $15.00. Put a SOS out. Maybe a mechanically inclined individual nearby would help you out. It's not that hard to swap out. The same 30mm fuel pump was used in a lot of different scooters. Yamaha fever comes to mind.

This is a serious "do it yourself" problem. Be sure to do things in order. Then reverse order. Seal it and make it a day.

OK, where is the Robot video?

I'm not sure this is a project I want to take on especially if the dealer will only charge about $150 for labor.

OK, it is 13 years old but done only 2400miles, which is nothing.

I understand you only have a starting issue when the engine is hot, not when it is cold.

Why do you think there is something wrong with the fuel pump?

When the engine is hot, I do not hear the fuel pump come on when I turn the key. Plus, it won't start when hot.

After it cools down for a while, the pump comes on and it starts normally.

Battery is fully charge and all connections are tight. 6 month old spark plug and air filter. What else do you think it could be?

do you have the service record invoice from the dealer for the 600 mile service with the date that it was done?

its very possible the recall had just came out when you scooter was in the dealer did install a new fuel pump. not that hard to do and doesn't take much time.

Unfortunately, no. I wish I did. That would definitely answer a lot of questions.

I talked to another dealer about this 2 days ago. It was the sister dealer to the one I bought the Vespa from. He was able to pull up all the info on the Vespa showing purchase date and the recalled pump being submitted to Piaggio. He also thought it was odd that there was no info at all about the 600 service in the computer.

Piaggio shows the pump was replaced about 2 years after the Vespa was purchased. I'm sure the 600 mile service was performed within a few months of buying it. I remember taking it in and waiting for it.

We're talking anywhere for 11-13 years ago. I guess my memory could be off, but I didn't think so.

It's the fuel pump. The fact that it begins operating after it cools down tells me it's not the relay or a fuse. How low do you run your gas tank? The pump relies on the fuel to help keep it cool. If you conostantly run your tank all the way down, it is hard on the pump. A clogged EVAP system from over filling is also hard on the pump.

Thanks for your input. I really never run the tank below half. My gauge will show just about ¼ or less, but it will only take 1 gallon to fill it back up. I've never had a problem with the evaporator system on this Vespa. (That I know of)

My fuel gauge is really off and I know it. However, I just can't get myself to ride the scooter when it shows close to empty. I guess it's the airline pilot in me.

If it is the fuel pump, how do you explain Bluside does not have any issue when riding the scooter when the engine is hot and that this fuel pump then refuses to work after a short stop?

Your LX has fuel injection, right?

These damn pumps!! I bought a 2022 GTS in 4/22 and my first one blew at 500 miles and then AGAIN at 7200 miles. I am hopeful they got it right with my THIRD pump in the bike.

I ordered a new fuel pump yesterday from my dealer. When they get it in I'll bring the Vespa to them for installation.

I spoke to a Vespa dealer today who said some of the fuel pumps are months out at Piaggio USA. Assuming it's the closest dealer to you, if they can't get it soon, ask them to call whoever they call when Piaggio USA is out of something, and you'll likely have it in a few days. 1D004191R or 641136 are the Piaggio numbers for that particular pump, and it's $240.

Well, the new fuel pump has arrived at the dealer and I have an appt. to have it replaced this week.

Interesting turn of events...

I rode the Vespa pretty hard yesterday just to burn some of the fuel out of the tank. I wanted to get it down to about ¼ so it's easier for the mechanics to drop the tank.

Both times I rode it yesterday, the Vespa's fuel pump came on and started normally after sitting for a few minutes.

I'm not sure if this was because of the lower amount of fuel in the tank or what.

Either way, I'm going to keep the appt and have the pump changed. It sure wasn't working and coming on earlier last week and I don't want to get stranded.

Thanks for sharing.

This time you heard the fuel pump come on after sitting for a few minutes. That was not the case in your earlier comments.

So I think indeed, there is somehing wrong with the fuel pump and I agree you best have it replaced by the new one.

It would be interesting to find out what is wrong with it. It probably is somewhere in a detail.

I picked the Vespa up this morning from the dealer. They put the new fuel pump in and I had them check and adjust the valves, if need, while they had the engine dropped.

It seems to be working just like it's supposed to.

The packing box points to it being a real genuine Piaggio part.

I guess you will test it a few times to check if the problem after short standstill is really gone?

I expect the old fuel pump is probably sealed and cannot be disassembled? Therefore difficult to find out what is wrong with it.

On the way home from the dealer, I stopped for gas. I spent a little more time at the gas station than normal and it started right up. Same thing after I got home. Started it about 10 minutes later. I'm sure I'll be a little apprehensive the first few times I'm out and about.

As far as the old fuel pump goes...I'm not going to bother with it.

OK, fair.

I keep in mind from your experience that when I do not hear the fuel pump coming up after switching on the ignition, whether cold or hot, whether long or short standstill, the fuel pump is most probably the culprit.
