Need help with my 2007 st13. 5000 miles. Cuts out when hot. Will start after up to 30 seconds but then cuts out quicker and quicker. Cant find the problem
St13 cutting out
- Thread starter irideforlife
- Start date
Try it with the gas cap loosened.
Done that. Changed pump. Done a general look under tank. Checked breather. When it dies all electrics like lights etc still work. Will turn over but not catch for a while
Did you replace the pump with a factory OEM part or aftermarket one?
Several of the aftermarket ones are providing non submersible fuel line, that will swell up and burst inside the tank, then you hear the pump wind up, thinking its working, only to have it bleed off pressure and stop running as yours is doing.

Was doing it before with original pump. It needs to get really hot before it starts to cut out. Once it starts it gets worse very quickly
With that low of mileage, your original pump probably died a slow death from sitting.
Again, did you replace an aftermarket pump this time?
I have replaced over a dozen aftermarket pumps after only a couple thousand miles and found the lines swollen and bleeding off pressure.
You may want to inspect your replacement pump and lines.

Thanks Larry. Any better? Have you stooped headbutting dogs? Some weird sports you have over there!
I've just been having a private chat with irideforlife - He Pm'd me. Although its far from my field of experience (on the ST anyhow), I knew I had seen a thread with these symptoms before - so I was hunting it down for him. I was looking for the post where you had experience of that with similar symptoms.
After pushing for more detail about what it was doing and when, This is what he told me.
I was also wondering about intermittent fuel pump circuit.

When the fault occurrs it needs to be tested to determine if there is both spark and fuel delivery. Missing one, the other, or both will determine the next diagnostic step.
With the above in mind, because it appears to be an intermittent problem my first reaction is to suggest testing the crankshaft position sensor and the speed sensor.

Where is the speed sensor and can you test them and how please
Check my problem last year. The speed sensor is expensive, check my post. I changed coils, plug wires, fuel pump, gas filter, fuel pressure regulator, temp sensor and other stuff but the final fix was the crank position sensor. You have to have a scope to check it. Local dealer wants $139 per hour. The sensor was under 100. Cheaper to buy and lose than 139 plus sensor . My 07 would work perfectly for 100km or so, then start missing. Once it would only rev to 6k then bounce down to 4k back and forth for awhile. It never did stop on me.
Enjoy the ride. Don't get frustrated, get even
Cutting out again | ST1300 Related
This is the 3rd time this summer that my ST1300 acted really bad. It was like cutting out when 1 accelerated. Idling along was not that bad but when I opened the throttle the engine acted like it lost all fuel or electricity. The gauges kept lit but the engine stumbled then picked up then...
