i have rough starts most of the time. either it will start and stall, or it will take 1-3 key cranks and a little engine rev. even with a full tank, and i just cleaned the injectors. also, i got a new started about 3 months ago, nothing fancy, just OEM. any suggestions?? i dont wanna mess my car up.

 

check your ecu to see if it's throwing any codes. i had similar problem and it ended up being my engine coolant temperature sensor. there are many possibilites as to what it could be, but my first suggestion is check your ecu. also, read the faq's if you haven't and all the stickies at the tops of each forum. welcome to the org

 

i actually had my ECU reset for my milage, but they say that could mess up starting. however the problem was still apparent before the reset. they said there were no codes. so ill check the FAQs. thanks

 

Clean your throttle body. Mine was doing that for the entire winter. I spent 45 minutes cleaning it and that sucker fires up every time. If your idles are low or waivering, that's a sure sign. I'm getting 4mpg more just from that. Good luck

 

same thing happen to me about a month ago

 

i have the same prob and last time i got the crankshaft sensor error codes. shes goin to nissan dealer tomorrow(she still under warranty) so im not gonna get raped by tha dealer. i'll let u know what happens tomorrow....

 

i just got my 95 maxima 4 weeks ago,, I have the same problem to a T. its a ***** to start. but when i finially get it running its perfect. My ECU just threw a Check engine light.. i will check it this weekend.and let u know.. keep me posted..

well i got the codes from the ecu..... 0407 and 0304
crankshaft position sensor and knock sensor...

what the heck is the crankshaft position sensor??


It takes my foot on the full throttle to start the car. once it warms up, i can shut if off and it wont restart at all.. Baffled!!!

 

i jus got my baby back and they said the codes they got were for vent controler valve. since i got it back today it seems to start better so i'll keep yall posted....started it again this morning and its A LOT quieter than b4. even my mom noticed it. i'll give it a couple more days and see.

 

If your car has the symptoms of having a tough time to start when cold...but once started everything is fine this is usually the problem;

1. Throttle body needs to be cleaned
2. Engine Temp. Sensor needs to be replaced.


If the car will not start unless you give it gas...and then you see a white dense cloud of smoke come out of the tailpipe after the start this is another indication that you have the problem mentioned above...just a more advanced version of the same problem.

P.S.-to make sure that you don't have a fuel system leak, such as an injector or fuel filter/hose leak; put your key in the egnition and turn it until the radio and all the dash lights come on but the engine doesn't start yet. Do this 3-4 times in a row, each for like 5 seconds. When you do this, the fuel pump is activated every time and builds up fuel pressure in your system. If your system is not leaking any fuel (from an overnight park) you will experience no difference. However, if it is a fuel leak issue, when you do this the car will start right up and then you know the problem is not as stated above (in line 1 and 2,) but more of a fuel pressure/leak problem.

hope I helped,

I have the same problem only i dont need to give it gas, it just goes (cough cough cough) much longer then i should while i hold the ignition key in the "start" position for a good 4 to 5 seconds intstead of of 2 or 3 seconds.
