Car starts with difficulty and occasionally does not start

 Today the car's fault has been troubling the owner for more than six months, the cause of the fault is that the vehicle is difficult to start, the vehicle does not start for only two general reasons, one is the oil circuit, one is the circuit. Let's start with the easy one! We first remove the spark plugs, open the key door to start the vehicle and see if there is ignition? See if there is spark here.

This means that the circuit is normal. Let's look at the fuel circuit again. It's actually quite simple to check the fuel circuit, there is a petrol detection port here and

Normally, when the vehicle is started, the fuel pump gets power and the pump will supply oil through the petrol filter and to this test port here. Let's see if there is oil in this test port?

Seeing as there is no oil here, next we go to the oil pump, which is all under the rear

seat, just under this cover.This is the oil pump. Let's unplug the oil pump and have a look, the problem has been found. The plug pins are all burnt up here.

Occasionally the fuel pump cannot be powered due to poor contact and petrol cannot be supplied to the injectors, resulting in the vehicle not starting properly. We pivot the pins a bit and

Then plug it in, start the car and see if it fires up? Well a successful start and the problem has been solved. We open the test port to see the oil pressure here and it has returned to normal.
