Out of the blue '04 Xterra super charged 4x4 left me stranded. Engine turns over and sputters and you can smell gas. Thought it might be fuel pump related, but my mechanic has had it for 10 days and can't seem to diagnose the problem. He says it cranks normally 3 out of 4 times. I will be taking the vehicle to another repair shop soon. Any experience with such issues? Any suggestions would be greatly appreciated!
