2003 Nissan Altima SL 6Cyl3.5L - Transmissions & Drivetrains
Car cut off in the middle of driving
We have been out of our car for 4 months: the car completely stopped as if someone turned off the ignition. The mechanic checked all of the spark plugs and says it was the computer. He ordered a computer, but that didn't work. He sent it to the dealership, but they said they only thing they could figure was it was the timing chain. We checked for recalls but there are none on this car. Another dealership says it's not the timing chain, but the key. The repairs for that worked for 30 minutes and alas, our cars still won't move. please help!

    Have they checked the fuel pump? Best way to check it is to find your filter, and remove it, then crank the engine, and see if you are getting fuel to the line. Also, has it been checked for timing? Possible.. I am sure thet if the dealer checked it.. some of my answers were checked, but you never know.

    I used to have this same exact problem & many dealers changed a lot of things & it did not fix
    Finally it was the sensor connection where connection was loose & needed welding Six years now. PROBLEM SOLVED. I wasted lot of money. But it was fixed it in 20 bucks

    I agree with monkshine, the fuel pump should be checked first since that would most likely be cheapest, then the timing if it hasn't already. You said you have been out of your car for four months, does that mean it was stored for four months and now your are trying to get it started? If so, your fuel may have gummed up in your lines preventing fuel from reaching the engine. If not, the dealer is probably correct as they know your car best, after checking the fuel pump and lines, have the timing belt changed.

    Your best bet would be to go to a Nissan forum and search for people having the same trouble. There are problems that are common among some makes and models. I'm surprised that the dealerships are stumped. Two things to check for are spark and fuel pressure. Can the vehicle be started after it sits for awhile? If so, my guess is a faulty crank position sensor. Make friends with a good "backyard" mechanic. Dealership mechanics are punks.

    If everything goes out (lights/indicators,etc.) , check the grounding cable. Loose or corroded.

    This has happened to me 3 times and it turned out to be the distributor, it is at the end of the camshaft on the drivers side and what happens is the seal gets weak and oil passes up through the distributor shaft and gets oil all over the electronics inside the distributor, pull the distributor cap off and is there is oil in there that is most likely your problem

    In a database of specific year, make and models, I see many, many confirmed fixes of similar stalling problems by replacing the camshaft position sensor. That was the fix the majority of the time. I see only one instance of a bad fuel pump, and a few timing chains. Logically, the thing to replace would be the cam sensor. The sensor is not expensive and easily replaced. I am wondering if anyone replaced it yet. I also see crankshaft position sensors being replaced. Many more times it is the cam sensor. At the present time is this car a no-start? It stalled and it will not re-start?
