2002 Nissan quest 3.3 replace distributor car starts fine all of a sudden just shuts off and will not start I wait a while and try to again in the vehicle started but then shut off again when put in drive or sometimes and park it will shut off can anybody help

Driving at 70 mph on highway one night and all of a sudden it stops in the middle of the highway, no dashboard lights, no inside car lights, no headlights, nothing worked. After about 3/4 hours of trying to jump it, it did come on for about 3 hours and then nothing again.

Van loose power. White smoke comes from underneath near muffler. And is very hesitant. Mechanic cannot find what's wrong. Nissan dealer charge to much. I need help.

At a traffic stop, after traveling, the engine died, it will crank but no power to gauge cluster or to fuel pump. I replaced fuel pump, checked relays and fuses and they are all good, I don't know what to do now

I have the symptoms of having engine mount problems as described in some of the website I've searched thru, also the YouTube description that shows how to fix it. Just want to know what's the estimate cost for this.

2002 Nissan quest up hills wont go more then 20 mph and check engine wont come on. Can someone help me.

It is held together by a screw, but the piece broke at the threads while the car was running, and it immediately turned it off, and it will not start. I know that the timing all needs reset, but I need to figure out the piece to replace before I can do that.
