Sounds very much like the coolant temp sensor
, this tells the pcm that the engine is cold, sometimes they fail and tell the pcm the car is at -40 degrees, the pcm then tries to compensate by keeping the injectors open for too long flooding the engine. the part is inexpensive, and normally easy to replace. It can be checked with a scan tool, or a volt/ohms tester,

Got a 2005 Nissan Altima it run for a bit can come up to a stop sign it will just die take 20 min before it will start again


well you need to identify what is missing. An engine needs ignition spark, fuel and injector pulse to start. (assuming mechanically the engine is ok. Like good compression and cam timing ok) A fuel pressure test is needed to see if it has good fuel pressure. Test for spark and injector pulse. If the fuel pressure is ok but it doesn't have spark or pulse it is usually and crank position sensor but on Nissans it could also be a faulty cam position sensor. Without the proper test equipment you will need to have a qualified mechanic diagnose it for you. I wouldn't start throwing parts at it.

2011 nissan sentra won't start


Thank you you can start by scanning for codes, but a 02 sensor will not cause a no start condition
We will have to pinpoint what the engine is missing.

Spark

Fuel

Compression
All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition

NO START 2000 NISSAN SENTRA 1.8 ?


Could be a computer problem among other things.
The computer grounds the injectors when it sees RPM and a spark signal.
You may need a shop that has a scanner that will read data flow in and out of the computer to find the problem.

2001 nissan sentra cranks but wont start


Dean, it looks like your on the right path ,with all 3 things as you stated it should do something, did you try a little starting fluid , you could use a timing light to check for good steady spark . what other kind of work have you done to it ? re check your work ,when you did compression test how did the plugs look =clean =soaked in fuel = nothing at all?

My 98 ford explorer wont start its turning over and getting spark and fuel


OK IF YOUR YOUR SURE YOU HAVE SPARK AND FUEL THEN THE PROBLEM IS AIR OR COMPRESSION I WOULD THINK COMPRESSION DO A QUICK COMPRESSION TEST AND I THINK YOU WILL FIND THE PROBLEM IS A BROKEN TIMING CHAIN ONE OTHER POSSIBILITY IS A PLUGGED CATALYST BUT FOR BOTH BANKS TO BE PLUGGED TO THE POINT IT WILL NOT START IS VERY RARE GOOD LUCK (WHEN YOU SAY YOU HAVE FUEL DO YOU MEAN THE FUEL PRESSURE IS GOOD AND YOU HAVE INJECTOR PULSE OR JUST THAT YOU HAVE GOOD PRESSURE THE INJECTORS MUST PULSE AND HAVE AROUND 45 TO 60 PSI (RULE OF THUMB) FOR IT TO START ) USE A NOID LIGHT TO TEST INJECTOR PULSE OR IF NOT AVILABE SUBSTIUTE A 194 BULB AND BEND THE WIRE TABS FROM THE BULB DOWN AND PLUG THEM INTO THE INJECTOR HARNESS (NOT RECOMMENDED FOR ASIAN OR EUROPEAN CARS ) THIS LIGHT WILL BLINK WHEN CRANKING OR RUNNING IF YOU HAVE INJECTOR PULSE

96 nissan sentra cylinder 1 misfire


DETERMIN IF YOUR PROBLEM IS ONE OF THE FOLLOWING BEFORE CHANGING ANYTHING .1.ELECTRICAL
2.FUEL RELATED OR 3. MECHANICAL.

PERORM A COMPRESSION CHECK TO ENSURE THE COMPRESSION IS GOOD .IF THE COMPRESSION IS IN ALL CYLINDERS PROCEED TO CHECK FUEL SYSTEM .REMOVE THE FUEL INJECTORS AND EXAMIN THE INJECTOR TIP FOR CARBON DEPSITS .CHECH FUEL SPRAY PATTERN ,ENSURE INJECTORS ARE ACTUALLY SPRAYING . THEN PROCEED TO EXAMIN THA SPARK PLUGS .LOOK FOR DISCOLOURATION OF SPARK PLUG ELECTRODES OR CARBON DEPOSITS. IN DIAGNOSING PROBLEMS ONE HAS TO SYSTEMATIC OR ELSE YOU WOULD BE WASTING MONEY AND TIME PURCHASING AND REPLACING COMPONENTS WHICH ARE NOT DEFECTIVE . GOOD LUCK .

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

1997 Nissan Sentra 4 cyl. Won't Start


That means bad injectors, or defective fuel pump, you probably need to replace the fuel pump.
