Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for using JustAnswer.com
When you say won't crank, do you mean the engine turns over and doesn't start?
starts then dies
If you step on the accelerator a little bit, will it start and run as long as you keep your foot on the gas?
no it dies no matter what you do
Lets try this,
Open the hood and unplug the MAF sensor. This is the sensor that is attached to the top part of the air filter housing.
After you unplug it, see if the car starts and idles, DO not give it gas. This is just a test
it may take afew min to go to shop and try
Not a problem. Get back to me after you try.
no that didnt help
You just tried it?
does the same thing?
You have gas in the car right?
Do you know if you have any codes stored?
cam shaft pos sensor and it andcrank sensors have been replaced
Can you give me a little more history on this issue. I see you put a used fuel pump in the car, along with a Cam and Crank sensor.
Was there a code for them? is that why the sensors were replaced?
Did you get the sensors from your local auto parts store?
What was the code you had?
in cold weather had trouble cranking and then would finally run and now it wont even do that
the number if you remember please.
yes parts came from parts store
let me look
Do you know what the code number was that you had?
no cant find it
Well have to start with some basic checks
Need to check fuel pressure
Since the car almost starts,
and need to take a fuel sample
Make sure the fuel is ok.
May want to take out the spark plugs and make sure they are not wet also
code number po340
if they come out wet does that mean plugs are bad
340 is the cam sensor
if wet it means the car is getting flooded
I can say this.
The problem could also be that after market Cam and Crank sensor.
Seen it way to many times.
After market electrical parts just don't seem to work right
the other code was po113
That is the Air intake Temp sensor
Did you just check codes now?
or this was the codes you had before?
That also indicates you may have a MAF sensor problem
but the first code was the original
Both these items can keep the car from starting, and I do not recommend after market parts for.
do you know how much pressure fuel pump should have it has 40
When you run into problems like this in the work environment, the normal thing to do since the sensor has been replaced is to assume it's good ( when it may not be ) so then you do all sorts of other checks and throw more parts at the car to try to get to start, then it ends up being the after market electrical part.
51 psi should be the fuel pressure
if you have 40, that is to low
ok thank you
