Just yesterday i decided to get fuel from a place i usually don't , after driving for some hours my car just shout off , i tried accelerating but i couldn't so i parked .

After some minutes i tried starting the car and it was up again , same thing happened today , could this be because of bad fuel , and if it is what are the necessary steps to stop this malfunction

My car is a Honda Accord 2005

    I bet it's water in the fuel, which really sucks with ethanol laced gasoline. You can put some fuel treatment in there which will take care of some water, but you may have more in there than your car can handle. I have no real advice for you so am leaving this as a comment. Oh, and once you find a gas station you like, continue to use it and you shouldn't have this problem again. Look for busy gas stations as they turn over their storage very quickly and don't usually have this issue. Dec 17 '14 at 22:31

    You may want to keep the tank topped up, so that if it is water, it's less likely to suck that through until you've sorted it all out. It would at least buy you some time.

  • @Calyth ... the gas will float on the water. Water, being heavier than gas, will be towards the bottom of the tank, which is where the pickup is at. Fuel level will not alter this. If the pump is going to pick it up, it'll do it irregardless. Dec 19 '14 at 12:16
  • @Paulster: So if there were water in the tank, and it sinks to the bottom where the pickup is, wouldn't you expect the engine to fail right away, rather than running for "some hours" and then failing? If there is a contaminant in the fuel, it almost sounds more like it's something that floats. Dec 19 '14 at 16:23
  • @Paulster2 That's interesting. I might have to double check my service manual. I was under sa slightly different impression. Though at least there's the evap and the charcoal box, so the engine may have started from the vapours while the car's parked.

The probability of fuel contamination is a possibility, but I would have thought that if it was the case, the vehicle would have shut down and would not have been able to be restarted. I would be inclined to think that you have a failing component. As it is apparently an intermittant fault I would be run the vehicle with a data logger attached to track a re-occurence, after having a vehicle scan.

  • I want to add to this answer, as it sit beteween fuel system and other failures. I had this Nissan D-22(Frotier, or Terrano in some countries) that would start without effort run a couple of minutes then it would die. After that toke a lot of engine cranks to start but it'd eventually turn on as always. Changed the 3 fuel filters it had, still the same. Checking the underside I spoted a leak which it came from where the hardline meets the hose, just before the filters. The hose was slit because of fatigue and from above was almost invisible. Spent $ 2 us, for a piece of hose and that was it.

EFI relay, in under hood fuse box on my 2008. Car would not turn over, left key in #2 position and tapped relay, it clicked and fuel pump came to life. Car then started right up.
