Hello, I am new here so I don't know if I am posting this in the right spot but here goes. We just bought a 2003 f4i. The FI light comes on and blinks twice, which I know is either a faulty map sensor or vacuum hose. I've looked all over the internet looking for a "brand new" map sensor. All I can find is a used one on ebay. I'm not about to buy a used part. Anyways, does anyone know where I may be able to find this part new?...ok so now i go out and try to start it and when i turn the key it wont cycle or start

 

Make sure its plugged in and the vacuum line is connected tight, both ends. Look around for any other vacuum lines that may have come off. Another vacuum leak can affect the vacuum signal to the MAP sensor.
If you still want to replace it with a new part, you will need to go to a dealership or an online source that caries OEM parts.

Btw, MAP sensors don't go bad all that often....

 

Agreed on the MAP sensor going bad its not likely......I'm not so familiar with F4I so I can help much more then that.

oh ronniesmailorder.com has parts and micro fiche to look at

 

ok thank you...ill be taking off the tank to look at the sensor and hoses probably tuesday...anything on a red light to the left of the neutral gear indicator? someone said it had to do with overheating...my bike was at about 188 degrees when it came on so it wasnt overheating...sorry about all the questions

 

The one to the left of the neutral indicator is an oil light, usually means dropping oil pressure if it comes on while it's running. It should be on while the bike is off.

 

Theres a ton of online sites to get oem parts. Start with motosport.com
