95 maxima will not start after it gets warm
I have a 95 maxima wit the 3.0 I changed all sensors and she will start up and run but once I stop somewhere and cut it up it will not start
|
need help - what do you mean by "cut it up" ?
|
My fault when I cut it off I can ride all day but soon I stop and turn the car off it will not start up till about 45 to 50 mins and then it won't start on the first turn
|
I have the same problem..
Did you find a solution? let me know please Thank you |
The original poster used strange terms.
Please describe YOUR problem , in your own words. |
Possibly leaking fuel injectors or a bad fuel pressure regulator. My Maxima wouldn't turn over with one leaking fuel injector when it was hot unless I kept cranking it while giving it a little gas.

This may have been mentioned before, but an Engine Coolant Temp Sensor (ECTS) could be failing and giving the ECU an incorrect temperature for a warm engine. It may be defaulting to a cold engine reading that would setting up a "rich mix" condition that is incorrect for starting a warm engine. A failing ECTS has been known to contribute to some hard to start conditions. |

I've experienced a condition like with two leaking injectors. Basically the leaking injectors o-rings let fuel from the pressurized fuel system drain into cylinders when the engine has been shut off. Too much fuel leads to a flooding condition. The only I could get mine to start in this situation was to hold the accelerator to the floor (at WOT) to let the most air enter the intake to clear the flood.

shouldn't it throw a code for that sensor though? i've been having problems with my max stalling after warming up and someone suggested this sensor before.
Sometimes sensors fail without setting codes. That sensor could be removed, then tested with a vom, a meat thermometer, and a pan of water which is gradually heating on the stove. Look this method up on you tube. |

My money is on a bad ECTS or FPR. I've seen both prohibit a car from starting after it's been driven a bit.

fpr is new, will a bad ects cause gas smell? i mean, i guess that would make sense being as that it makes the engine think its cold when it's warmed up.
A defective one leads to stalling. Due to insuffienct air flow. The computer will reduce the amount of fuel injected. |

No, it controls air flow.

Gotta disagree with you. The ECTS reports temperature to the ECU. The ECU adjusts the timing of the fuel injectors accordingly to increase or decrease the amount of fuel. Nothing controls air flow except the throttle plate and the IACV.
