Doesn't want to start

11 posts in this topic

My 2013 500 will only start if I floor the gas pedal and then once it starts I have to pump the gas until it warms up a little it sounds horrible until it warms up.(around 20 seconds)and then it will stay running. The exhaust smells like raw gas for a little while. The throttle body has been changed. Someone suggested the mass air flow sensor could be the problem ( is that the MAP). It has been to 2 different shops with it not being fixed. I haven't been able to ride it since last fall.

Does anyone have any suggestions?

This is the only problem I've had with it since I bought it. Yes I talked to Massimo they said sound like the fuel pump but one shop said they tested that and it was fine. The second shop had it for 5 weeks and never called me on it or even worked on it. They wouldn't answer their  phone or return calls after I left messages. But when I dropped it off the guy said it sounded like the mass air flow.

Could be something wrong with inlet (Fuel) valve on the head not opening far enough...

No it's not fixed yet. putting a MAP sensor in it today. Thats what the mechanic says is wrong. Ill let you know if it works.  It has actually gotten worse. It wont even stay running now when i let off of the gas. Going to be tricky getting it on the trailer to take it the mechanic.

The map sensor wasn't the problem. Now have no idea what it could be. It's getting to much fuel and flooding and then stalling. This think hasn't been fixed since last fall.
