tyrone? I thought you had a Belta? Did you do as I suggested? Another member had a similar issue and it turned out to be her grounds. We suspect the vehicle might have been in an accident and the grounding points were painted over.

Ciscobear, no I'm sorry it must have slipped my mind...could you pls repost it here again and I will try. I'm zero where these cars are concerned so you'' probably have to explain it as simple as possible :)

CTScott, another mechanic had a look at my car y'day evening and started it. He didnt have a scanner but when he started the car and I explained to him the situation, he said its the fuel pump and not the fuel filter. Reason being that the car runs smoothly after that and there are no jerks or problems in the pick of the car. He says since its only on cold startup it seems to be a problem of the fuel pump pressure initially as it starts up.

I would think that if the fuel pump had an issue that it would be visible on more than just start-up.

CTScott, I just wanted to confirm from you before jumping to any conclusions. What would be the tell tale signs of a fuel pump issue if it were so, if you could pls let me know?

....and yes the Belta is what I have. It was imported at 43,226 km but I believe its called a Yaris in Canada/US so thats how I mention it when I post on these forums

CTScott could you let me know what other signs would be noticeable of a fuel pump issue so I can look for those???

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?
