Hi! I am writing to you about my maxima which will not start!!

It had an alarm when i bought it 2 years ago. One day it started ringing for no reason, I turned off and the car didn’t start. I went to a place to remove it and the car then started perfectly. The following day it didn‘t start. The battery is fine, the alternator is fine, I changed some things for new ones, cables, and so. I also checked the ECU and it was fine. The car started one time but again it didn't last. The problem is that it does not start in cold (after being out of use for about 7 hours or more) The starter works fine, the distributor too. The ignition coil is new. Fuel gets fine to the fuel pump. I have spent tons of money and the car doesn't start! What else could it be?

Thanks in advance!

I had an Infiniti that would start and die out when the motor was cold. Turned out to be a bad MAF.

 

I`m sorry... what is MAF? i`m from Argentina, and my ingles is not very good!

 

MAF = Mass air flow sensor





You can test this sensor by unplugging it..Your engine will not rev over 2500rpm when it is unplugged...

 

Also, many people have had problems with the Engine Coolant Temperature sensor.

 

thanks!! where this the temperature sensor? it is the termoestato?

 

 

What He showed above and no it's not the (I think you said) thermostat. This is a sensor that tells the engine computer the engine temperature .

 

ok... thanks!! and, as I realize if that does not work?

 

i have already tried this, I disconnected the air sensor and nothing happened, now, I don't know what to do to find out if the temperature sensor has problems
Thanks!

 

Check your local car parts store for the price of the sensor,they are cheap here in the united states,but i don't know about down there...

 

Option A) take your car to a good mechanic

Option b) repeat your problem in spanish(en Espaniol ) and hope that one of these guys answering your questions are fluent in spanish.

 

Here's a writeup on how to test the temperature sensor.

it follows not start

 

¿Reemplazó usted el sensor de la temperatura de líquido refrigerante?

¿Cómo es probar para el fire[spark]?

¿Cómo prueba usted para el combustible al motor?

 

* Ya lo pedi cuando lo tenga lo cambio, intenté con las otras ayudas.
* En el encendido llega chispa. (spark)
* el combustible escucho que carga la bomba y además saco la manguera del filtro de nafta y sale nafta al intentar encender

* tomorrow i can have the sensor, I tried with the other aids.
* In the ignition the fuel arrives tipsy (spark)
* Which the fuel, I listen that it loads the bomb and in addition coat the hose to the gasoline filter and leaves gasoline when trying to ignite

 

 

Option a man, definitely option a.

ps. Option b that you tried did not work. Good luck with the bomb.

 

If the air sensor (MAF) is bad, it should still start. if not un plug it. Disconnect it.

but you have spark/fire/ignition and fuel/gasoline and compression (engine turning) it should run. Maybe not good but it should run.

Check that you have spark/flame/ignition, and that its happening at the right time with a timing light.

Check that you have fuel/gasoline getting into the engine with a fuel pressure gauge. And you hear the injectors ticking. Put the handle of a screwdriver near your ear, and the tip near the injector.

the option "A" to already tries 2 times, now it I am trying again (it is the third time that I take it a good mechanic) the problem that in Argentine, there are only 100 or 200 maxima´s, and so nobody understands things so specify

 

Does not start – new information / pin out


The car will not start! No pulse reaches the injection. The remaining things work ok. Can anybody help me?
The mechanics needs to know the pin out of the injection control unit. Does anybody have it?

Thanks a lot!

 

What? Maybe a bad ECM if the the injectors aren't pulsing. Check the relays. Also it should not matter that mechainics don't know Maximas. Sounds like they just don't know how to work on cars. In the USA you don't take a Maxima to a mechanic and say do you know how to work on this?

 

You haven't tried to get a car fixed in Seattle!!
