I have a mitsubishi pajero exceed 2800cc.
This problem occurs everytime the vehicle has to start from cold. It would start perfectly and idle but when an attempt is made to move vehicle it fails after several short runs. Checks reveal that the manual primer pump has to be pumped up before it can start again and run. From pumping it was observed that the pressure in the primer pump was "soft" initially and then would become "hard" after several pumps. The vehicle would start again after a couple tumbles and then run again for a short distance and then the same thing happens again . This would go on until the engine warms up to operating temperature ( just b4 half line on gauge) at which time the vehicle would operate without further problems..
Is there anything electrical that could be wrong with this system or or is it a mechanical problem with the seals (sumone suggested) ?
Fuel lines were changed , fuel filter was changed, manual primer pump was changed and the problem still occured.
I await your urgent response.
Thanks..
