Hi,

I have an Altime 1993 and 2 days ago, just 2 min after I started, my car had no power when I tried accelerating, it was sputtering. It was running ok thouh at Idle. So decided to go back home but as press again a little more on the gas to try to feel the problem it stalled, and was not able to start it again. I pushed it on the side
and troubleshoot it. When I turned the key to ON I did'nt heard the fuel pump priming. The fuse was OK and the relay also. So I've check the pump and the 12V was there, and the pump was giving me an open circuit(infinite resistance). So 400$ CAN later, everything was OK, the problem was really the fuel pump.

My dad who owns a Stanza 1991(same thing as an altima) had also aproblem with is fuel pump. But the effects where different. The car would be hard to start sometime, or would have a roiugh iddle, stall etc. In is case the resistance of the pump was OK, wich made the troubleshooting harder. But once he changed the fuel pump, all his problem were gone.

For sure you want to be 100% sure it's really the problem before spending 400$ for a new fuel pump !!

So here what you can do:
check the resistance of the fuel pump (should be very low 0.5 to 5 ohm)
try hitting hard on your fuel tank with a stick, if you car start easily afterwards or runs smoother, you'll know it could be related to the fuel pump.

Good luck.
