Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
What usually causes this here is a lack of fuel to the injection pump or fuel injectors.On a cold start or first start after it has sat awhile the engine needs max fuel to start.If there is any kind of leak or even fuel seep on any of the fuel lines or fuel components this will cause this issue here and the leaks will need repaired.This needs checked.
If there is an issue with a restricted fuel filter this will need replaced to correct this here.This should be done every 10,000 miles/km in most cases
If there is an issue with a low pressure fuel pump in or at the fuel tank this can cause this as well as some of these models have a low pressure pump.
If there is no low pressure pump and the filter is o.k. and no fuel leaks then I suspect the fuel injection pump may be at fault here needing replaced.
The fuel system does need to be tested/checked further to pinpoint and repair the fault here.
