This scooter has sat for several months. It has 1,378 miles and in good to like new shape. It is currently in the shop, which is a Piaggio/Vespa certified (however recently certified).

The scooter will start and dies after 5 seconds. The fuel pump has been replaced with a new one, fuel filter, fuel lines all check out good. Gas tanks flushed, injectors cleaned. Any ideas on what will solve this? I believe I must something electric, just have no idea what.

Hi Javen - Welcome to MV.

Has the battery been tested? Perhaps your shop should drop a new battery in and see if that has any impact.

I'm sure others will be along with suggestions.

many possibilities here.

has it been sitting?

how many miles?

service history?

do you have the master key (that's the brown one)

i'll roll some dice here and think that it's been sitting and you've got a problem with the fuel system; either in the carb or at the tap/lines.

1,378 original miles
I bought from an estate sale. Owner passed. Not sure on service history. No keys. I had ECU removed and sent to a Piaggio/Vespa dealership in Austin, Tx. They made keys. Would start and run for 5 seconds. It is in shop in Tulsa. I found fuel pump in San Diego dealership. That did not help same problem. They clean fuel injections, gas tank. Filter and fuel lines all good.
It is tagged and titled in my name.

If itís in the shop, sounds like itís the shops problem. Let them sort it.

Youíre paying them to iron it out. No sense in throwing WAGs at it with an intermediary.

Good luck!

There in lies the problem. This is the 8th week in the shop. Thatís a lot of labor for not much return.

Simple question. Have you tried spraying starter fluid down the intake and see if it ran longer?

I have a new to me 2012 Typhoon, it gave me some trouble. I figured out it was not getting fuel, I checked and changed the fuel valve. Still would not run correctly. Turns out the vacuum line at the T was cracked. I cut it back and reattached it. Running problem solved.

If I had not had time to work on it in daylight I may not have found it.

For you it might be worth a gander.

i don't know what kind of shop you've got it in, but they should work the diagnostic tree. the only curve ball might be the immobilizer, but there's enough info online that shouldn't prove much of a problem. but if they're not versed in scooters, you might be looking at paying them to learn.

you need fuel, compression and spark to make it run. but you need them in the correct order to make it run right.

if i had to guess, you've got a fuel delivery problem.

but playing mechanic via a game of telephone is always a crapshoot.
