2004 Scag TT 27hp Kaw- Randomly dying

[presta24]

I have ruled out coils and vapor lock. Next up will be to test the fuel pump I guess.

Fuel pressure gage was going to cost as much as a new pump and filter so I just went ahead and replaced the pump and filter. Viola. Problem solved. Could instantly tell I had power back. And ran for 45min with out dying.

So do you think it was the filter or the pump?

Did you ever disconnect the hose at the pump and try cranking to see if it was getting flow?

I think it was the pump. Not sure why it would die when hot if it was the filter. The filter was also full when I took it off.

Also, in my diagnosis I realized it's a 25hp, not a 27 lol.

I also had to cut the pigtail off the old pump as the oe kawasaki pump had a different clip

Electric pump or vacuum?

Electric

Fuel injected then? O2 sensor?

Not familiar with some of the newer stuff.....but 10-15 year old stuff....the only electric pumps were on the injected stuff. And Im only familiar with the kohler injected stuff

I questioned that too as I assumed all carbd motors were vacuum. But I am no mechanic. This is the motor, and the pump I bought. My Scag is a 2004 so its an older engine. But the same specs as the one below. Runs great I put about 100hrs a yr on it and the oil is still clean when I change it in the spring. I would like to stab the engineers who placed the oil drain where it is. Ordering a fumoto valve for it so next year i dont spend an hr cussing the paint off the walls.
