Help!

I bought a 2008 Kawasaki kfx450r yesterday that will not start. The fuel pump primes and it will not start. The EFI light flashes as I try to start the bike. It has no codes. Has great spark. Ive checked the fuses and relays all seems how it should.

Check the vacuum hose that goes from the throttle body to the map sensor.
It's right under the front of the seat

For the vacuum line... just make sure its connected to the throttle body on one end and that its connected to the map sensor right beside of it.

The tps sensor you need a volt meter and your going to have to have some needle probes to make connection with the two wires because you cant un plug it to check.

Its a touchy job but nessicary. The spec you need are going to be on the page, duster sent to u already. Or download the manual...its free

(Your quote from above) The EFI light flashes as I try to start the bike.

When the Fi light flashing when starting is showing the vehicle down sensor/ tip over sensor is activated...!!

Check it first...see picture

Hes right and if you want to eliminate it then for like 40 bucks u can get one on ebay that fools the bike and always says to go ahead with start. It's called a kfx450 tip over switch eleminator.
