Question about 2002 Nissan Sentra

1 Answer

Cranking but doesnt start, or intermittently not starting

After work, is started the car, it cranks but doesnt start.. I used the other key to eliminate keycode problems,. still not working., I removed the sparkplugs and coils to check,all ok.. moved to the fuel pump, it is pumping fuel when ignition on.... tested the injector connectors from ecm... 12V and pulsating 12-0 during cranking....
sometimes it is starting... i suspect now that maybe crankshaft position sensor or camshaft position sensor might be the cause.. but i dont know how to test them....
Please help, Thanks.

My car does the same thing...sometimes it wont start....have to turn the key off then when I crank it again it fires right away. Possible that the in tank fuel pump pressure regulator isn't building to the proper pressure. Nissan did post a recall....under warranty *recall* I might add.... there is an updated pump that will cure the problem but since you most likely are out of warranty it will cast $400+ for the part plus labour if you can't install it yourself. Call nissan to verify if your car is affected by referencing your VIN with them. Dave.

Why would turning the steering wheel while cranking engine gets my car to start?

The ignition switch in the column most likely has a break in it. So when you move the steering wheel, it moves the wire so it completes the connection when you turn the key. Have the ignition switch replaced.

My 2004 Jeep Grand Cherokee started perfectly yesterday morning. After stopping, turning off the car for about 5 minutes it would not start. I had it towed to a repair shop, where it started and all tests...

A definition: cranking is what happens when you turn the key, the starter engages and turns the engine. (term comes from when that was done with a crank that you stuck into the front of the engine to start it, before electric starters were invented) Turning over is the same as cranking. Starting is when the engine actually starts, even if for a brief moment.
Now...if the engine turns when you turn the key it is cranking. Was it doing that? If not, the problem is either in the battery, starter/starter relay or security system (sometimes) or the ignition switch. If it is turning and not starting, then the engine needs to be checked to make sure it has spark at the plugs, and fuel going into it. These problems are different ans some can be easily solved.

2002 Hyundai Elantra not starting intermittently

The whirring sound is more than likely your fuel pump. Give it a few seconds to build up pressure before cranking or have the pump replaced.

Mazda Tribute Intermittent Starting problem

I can think of 2 possibles,it could be a bad battery cable or an intermitent short in the starter solenoid, check or have the battery cables and there connections on both ends first not only are they a cheaper fix but the problem you describe sounds like a current flow issue.Test them with or have them tested with an ohmmeter they should show o ohms resistance,and while not attributed to the problem I do not reccomend using Bosch spark plugs of any variety,the best plugs for any Japanese vehicle are NGK's,this comes from my personal experience with them and other techs that I have worked with.

Hard to start warm engine

Sounds like you have a problem with your fuel injectors, either they are working to much or not enough once they get warm....

Take it to a shop ant tell them you want the injectors tested.

Turn key 4x to build pressure, on 4th try complete Start seq.

is the engine actually cranking when it doesnt start or do you hear just one "click" each time you turn the key? if the engine is cranking, i would suspect a fuel problem, possibly fuel filter if it wasnt changed when the fuel pump was done. if it is not cranking and you hear one "click" upon turning the key, i would suspect faulty starter or connection problem.
