Jiangling Domain Tiger 7 diesel four-wheel drive pickup truck can't afford to refuel.

Maybe the oil pump is broken or the oil pressure is too low.

Check the pressure of the gasoline pump to see if the gasoline pressure is insufficient. Under normal circumstances, the gasoline pressure is 4.0KP. If it is lower than this value, there is something wrong with the gasoline pump.

It may also be poor oil quality. The poor quality of the used engine oil will affect the gasoline filter element and oil circuit, which may lead to poor oil supply, thus accelerating weakness. Or inhibit carbon deposition. Throttle carbon accumulation will affect the intake, resulting in insufficient engine power, and the car can not speed up when refueling.
