Question for all you mechanics/Techs.

Water in the fuel?? With prices some stores are getting creative...

If you smelled fuel that usually means it is not getting any spark to ignite it. I would guess it could be the Crank Position Sensor or the Cam Position Sensor if it is a 2.5. I think there is a recall out on the crank sensor or it will be out soon if I remember correctly.

i would 2nd the crk sensor they have been having alot of issues with these again

NOT Titans!!!!

As far as I know it's only on the 2.5 Altima's 05 an 06.

Its the cranks sensor.
Call nissan,and get them to come pick it up.
I believe the recall was for cam ,and crank sensors ,but usually its the crank sensor that fails 1st.

Lets us know what happens.

I have to agree with the guys above it could be those sensors. I saw the recall on those sensors earlier this week but I have already changed both of them when I started having a problem with my 2002 2.5 altima. But since then the only problem I have now is that I think my cat or 02 sensor is bad. But let us know what happen.

The cat and O2 sensor could have been damaged by raw fuel.

can you explain a little more? See before I got a code I had to weld the housing for the top 02 sensor because it was coming off.

I wish I knew what to tell you, but the techs from Dechard (where these engines are made) told me that raw fuel could destroy these cats. I hope the sensor was out while you was welding, that could damage it. One more thing, just so everyone knows, disconnect the negative battery cable before welding on the vehicle. You could damage modules or set off the airbags.

allright it was the battery i guess. What was weird though was that it was cranking like crazy but not firing. So just for Sh!ts and giggles I jumped it with the Titan. Started right up! Replaced the terminal and now it wont keep an idle. Do I need to reset something?

Hate to tell you , but if it was turning over, it wasn't the battery. Now having the car set there and letting the fuel settle down might have done the trick. You might have flooded it causing the fuel smell. Hop e it was only the battery for you. I think you or the wife flooded it. Did you pump the accelator? When you took the battery off, it might have reset the ECU and allowed you to fire it up. Just two possible scenarios.

You really need to get it to the dealer.
With the crank sensor it is a hit or miss situation.

It was coincidence that it started when you jumped it with your Titan.
The sensor could funtion normally for a day ,and then fail the next.

That was one of the main reasons why they issued the recall.
Some owners of affected vehicles had engines shut down while driving down the road.

Take it to the dealer. A bad sensor could shut down the car at a point that could cause a bad accident such as a left turn in an intersection. You never want to risk that.

Maybe you could put on some virtual pants and go troubleshoot it some more. Cranking and smelling won't get much in the way of actual or virtual repairs done.

Good actual luck.
