Starts the stalls immediately then wont start again for a few tries. Cranks strong new battery I cleaned the fuel pump screen filter and polished the spark plugs also added stop fuel injection cleaner. I listened to the injectors they all sound the same. Once car is running it's fine.

This does sound like a fuel issue so even though you cleaned the screen, we still need to know what the pressure is that it is supplying.

You PSI should be almost 50 so let's check the pressure and go from there. Below is the spec from the manual.

Thanks
