Fuel pumps typically fail completely, where they just stop pumping fuel. In that case the vehicle would either not start or would only run for a couple of seconds and then die.

Thanks for the explanation.
Just another development I thought I would share with regard to my problem. I was told by someone to switch the key to acc wait about 20 secs and then pump the gas pedal a few times before starting. I did exactly that this morning and yday evening after the car was parked for about 8 hours and voila it started without that sputtering sound on both occassions :) What could this mean???? Could anyone explain? |

This morning I started the car and it started fine........strange. I did not wait 20 secs or pump the gas pedal. Although I switched it to acc and waited a few secs. Will check again this evening after work when the car will have been parked for about 8 hours and see.
Was there something choking the fuel filter that passed through or something????? |

A fuel system cleaner won't hurt, but likely also won't help much. If there is stuff in the tank that was plugging the filter, but eventually washed off, i may still be sitting in there and may repeat the plugging. It may not be a bad idea to eventually drop the tank and clean it and the filter. I just pulled the tank out of one of my Yaris this week, so I could do some welding above it, and it really is not that much work to do.

It ideally should be replaced. It is a mesh pad, so while I had mine out I blew it out with the air compressor.

Update:
Just wanted to update for the benefit of those who contributed and others who may read my post.
The other day while talking to my car electrician he told me that he was 99% sure, in his experience that its the starter motor that probably has to be serviced/repaired. So he told me to lets give it a try before going for the expensive fuel filter replacement. When he removed that starter (which was a pain) as its right under the airfilter box, infact at the bottom. Not much space. The bushes were cut and had to be repaired and also the inner spindle was loose. (Forgive me but I'm not familiar with the technicalities :-p) Anyways, he cleaned up the whole thing and after getting the bushes repaired, he fixed it back and now that sputtering problem at startup seems to have vanished so far, 3 days down the line since he did it. I remember on my 1st Gen vitz too he solved a similar problem regarding startup where he diagnosed the armiture was damaged and needed replacement including the bushes in the starter.... which resolved that problem too. |

Hi Tyrone, thanks for updating the post. The same thing just happened to my Yaris this morning. I never had this issue for the 4 winters I drove it. My problem is I'm guess I sued 10-30w syn motor oil instead of the 5-30 recommanded. it only happened to my once and I'll be back if this issues continues for me.
