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?
