hello I have a Toyota landcrusier 3.0 td prado I have trouble starting it changed heater plugs and fuel filter still the same and sometimes when pull off it wont move just very slow

I have a Skoda Fabia,no problems at all.

Do you have power at the heater plugs?

Cold Start? Hot Start? Does it run ok when it warms up? Any blue / black smoke?

Could be an air leak in the fuel system, could also be a number of other things - need more info to help narrow it down.

Does it have a MAF or Air Mass Sensor?

Yes

Not sure were it is

I did a Google search and it brought up this:



Not sure if this relates to your exact model, but could be worth a try:

Just make sure you use proper electrical contact cleaner. I use this stuff, which is very reasonably priced for Halfords:
