Some how I've become the neighborhood expert I think I need to move. The neighbor approached me and asked what do I think could be wrong with their 02 Altima 2.5L with 190k. Starts and runs for a moment then stalls out. Mechanic told them it was the fuel pump... could be. The problem is it burns 5 quarts of oil a week and has blow by bad enough pull the oil cap looks like a chimney. I told them $200 for a fuel pump sounds like a waste of money probably be better off junking it. A new engine runs over a $1k from what they said.. told them they could buy a good used car for that. Which years did the cat break up and kill the engines? Also told them that was a possibility wouldn't recommend a used engine.
