I have an issue with my sc vx, it's very slow to start.

Key in, pump primes, press button, turns over for approx 10 seconds before Starting.

Battery has good voltage and I have found that if I turn it over for a second stop then try again fires straight up! Fueling issue? If so where's best to start cheers

Check pump pressure, had exactally the same. Turned out to be a split pipe inside the fuel tank.
Most obvious from the gauge was how after priming before starting it rapidly lost pressure.

What Chris said. Exactly the same issue and solution.

You can check the pressure by priming the car on the ignite after it's been off a few hours and opening the little valve on the fuel inlet pipe, fuel should squirt out so get something ready to catch it!

No fuel, no pressure.

Cheers got the pump out pipes all in order but the pump had a bad rattle new one fitted it's all good!

Redo the fuel learn if your on OBD Tuner.
Likely the fueling will be off as it tried to dump more in to compensate for the lack of pressure

Yes do a new learn because the ECU has something like a 10% margin of self correction. If the pump had been a problem it'll be skewed.
