I am not familiar with this model but you don't mention how old this car is. Pumping the accelerator works on last century cars with carbureters because they have an acceleration jet in the carbureters which squirts petrol into the engine to create the rich mixture needed for starting. I suspect that your car is probably newer than this and the engine management system doesn't know that the engine is cold. Check engine temperature sensors for correct operation and replace any that are not working correctly.
when you accelerate real fast you are getting the CPU to allow large amounts of fuel into the chambers to be burnt. Un fortunately if everything else is not prepared for this surge of fuel it puts the fire out as combustion requires a ratio of 14.1 to combust properly. When you accelerate slowly the faulty sensors struggle to keep the ratio right. So run the fault codes and check which sensors are failing .
Could be fuel or ignition. If the coil or ignition is weak, you may not have enough power to fire the plugs under load. And if the fuel pressure is low, you may not have enough fuel under load.
If your motor starts easily but will not run when you press the accelerator, it is most likely a fuel fault. Check the fuel filter for blockages and replace if necessary. Otherwise check your fuel pump - it may be getting very worn.
Sounds like a fuel problem...something is restricting your fuel flow....clogged fuel filter (1st check and cheapest) or a bad fuel pump......second, I would ensure you are getting proper fire.....wires, districutor parts and coil. Good luck
You got fire and fuel .............. you may have water in your fuel system or your fuel injectors may be bad . Try some stp gas treatment before checking injectors .
it's look like the problem came from the injectors. they we're clogged. because hen the ngine still cool, it need much fuel than at working temperatures.
If it wasn't getting fuel or fire it would not run at all so that is not the problem.
