Number one and four coil failure

Hey Roy.

I'm yet to check the fuel pressure like you advised because my tech is not available. He'll need to come over to my house to run the test. But just to let you know, still, I've taken the car out in the past three days but on very very short drive. The car didn't give any problem as mentioned before. However, I'm not confidence enough to take it on long drive, say to my work place, because I'm not sure of the car. Is it suppose to allow these drives even with the problem? And, just to know, supposing the fuel pressure is actually the problem then what would be the solution?
Thanks.

Hello Roy,

I instructed my tech to replace the fuel pump like you suggested. He was still considering something else as the culprit but I insisted on the fuel pump so he went ahead to replace it and that actually solved the issue. I've used the car for a week straight and no recurrence of the problem. I'm so grateful Roy. Again, thanks a mil.

Hello Roy. I think I'm beginning to have issues with the fuel consumption. I think the car is consuming more fuel than it's necessary. I have also observed of late that the rev is usually high when I'm going on slow( say driving through many potholes). What could be the culprit here? Thanks.

Thanks for the reply. But I might have been hastily in the post. I'm sorry for this. The deception into thinking the car was consuming too much fuel was because of the fuel gauge that stopped working. Actually, the car stopped while I was going to work. I thought it was fuel. After work I came with fuel but decided to try the car before putting the fuel. I was surprised to find out that the car started. It turned out that there was fuel in the car. Why did it stop? I asked myself. The way it stopped was like the last issue that's got to do with the fuel pump. I called my mechanic and told him he's got to change the fuel pump. He said that he would check the fuel filter for blockage. I expressed doubt (I might be wrong though) that it could be fuel filter since car would eventually start well just like it did with the previous fuel pump. I have intended to ask him to replace the fuel pump. I do hope you see it this way too. If you think otherwise, I'll appreciate your advice. My question, however, is, is there something that could potentially be ruining fuel pump in cars? I hope I'm explicit enough. Sorry for the long write up. Kind regards.

Yea, but to the question, is there likely anything that can be causing damage to fuel pump? Supposing the fuel pump has gone bad again. Unless it was a coincidence. Because in the last one year I've had fuel pump changed like four times.

Not sure. But I know they were of different makes. Anyway, I had the fuel pump checked by two other mechanics. They said that the fuel pump has no fault as the pressure was okay. But I wished I knew what made the car stopped only to start well much later. Please Roy tell me, is it possible that the fuel pump could have failed only to work well much later? Or, do you think something else apart from the fuel pump could have been the culprit? Thanks.

Okay, thanks. I'll check immediately something similar happens again. Kind regards.

Hello Roy
Still on the issue of the pump, I observed two similar scenarios. First the car was on a slanted position (two left tyres were on a raised platform while the other two were on a lower platform). It was on idle. I observed that there was no power as the gas pedal didn't respond well. Then eventually car went off and wouldn't start. But when I brought the car to a plain ground, it started well again and the gas pedal produced enough power. I returned the car to the slanted position just to be sure and the same thing happened. The same thing happened a few days later again. There was enough fuel, in case you may want to know. Would it be wise to still believe it is a fuel pump related issue?
Robin.

No, I didn't. It was at home and my mech wasn't available.

I just checked pressure when car is slanted and when in flat position. Pressure is low when slanted but high when on flat. And same like I said before. Car loses power when slanted but revs well when on flat.

Okay, I wouldn't say I quite got you. But with what you just said, what would be the next step? What should I do now? Thanks.
Robin.
