I have a problem with my maxima since one week ago,i was running normally with my car and suddenly started losing power but still running, when i stop for fuel in a gas station the car did not start anymore. i check the spark and its right, the fuel pump its right (i change it for a new one) but still the car doen't work. the computer was checked in other car and its working good. i suspect on the timing but the mechanic says that its right. please i need help urgently
because i see that the problem is getting complicated.

I don't own a Maxima, but I have been looking at this site because I am thinking about picking up one as old as yours. I had a 1988 Chevy blazer once that all of a sudden had the same symptoms. Turned out to be the catalytic converter. The mass of material inside the converter melted and pluged up the converter. If your exhaust is plugged up, the car will not run. Check it out.
