I was driving the car when it start to lose power tried to park in the road side, the low pressure oil light came out then the car was off by itself. Checked the engine no oil. No leaks when I refill the engine with oil. Try to start the car but it would not start, it cranks but sound of backfire come from exhaust. Cleaned the sparks. No benefit.

Often times a backfire is an indication of excessive fuel entering the engine. Do me a favor, take a look through this link, and check the things it mentions:

If possible, record what it is doing, upload it, and then I'll be able to hear and see what is happening.

Let me know if the link helps or if you have other questions.

Hi,

Okay, after listening to the video, we need to check fuel pressure. It sounds like it may be low or the pump has failed. Here is a link that explains in general how to check pressure:

Here are the manufacturer's specifications:

Thanks. I did the checked and clean the sparks and coils. I put a new fuel trail pressure sensor. I used light tester to check the voltage of the fuel injectors its ok but when I checked the fuel trail sensor cable the light was not as bright as when I checked the injectors cables. I connected the fuel pump directly from the fuse box. No change. The car did not start and still acting the same.
