J30 engine crank then stop after replacing knock senor and injectors

[dcunningham]

Replaced knock sensor and six injectors now the car just turn and stop like battery go dead start just click. Gas coming out of throttle body and egr tube.

If fuel is coming out of the Throttle body it sounds like the upper O-rings aren't seated.Did you use new upper and lower O-Rings on the Injectors ??

[dcunningham]

Yes, I purchased new injector from Orielly auto parts and they came with upper and lower oring. But I went back to the store and looked at a new one and they look different at the base than the one's I removed but the guys at the parts store claim it's because mine are the original injector and that is why they look a little different. I removed the spark plug from the number two cylinder and it was full to the top with fuel. So I turned the key to the on position ran back over and I could here the fuel just pouring into that cylinder. I think I might have the wrong injector's for my car just not sure. But they are saying this is what the computer show for the J30. You think I should return theses injectors and purchase new ones from dealership ?

[yodawill2000]

I would.And for Dang sure DON'T TRY TO START YOUR ENGINE !!!

It will hydro-Lock and destroy your Valves/Rods ect.

I got the two Ive replaced at Autozone. (90 bucks give or take each)And bought the O-rings from everythinginfiniti.comNo probs in two years.

Here's the cheapest place to get OEM injectors.http://www.infinitipartsusa.co...gid=0

Okay, I will remove the injector and return them and order the new ones from that website. When I initially put the car back together I did try to start it for i didn't know at that time I was dumping fuel but it never turned over a full revolution before stopping. Sure hope no valve damaged occured I guess there is no way to tell until I start it up?

Thanks for your help.

http://www.conceptzperformance...9.111OEM injectors but better deal. They come with the o-rings and shipping is much cheaper with concept z.

http://www.autopartsway.com/au...40622Even better deal. Get the Bosch ones. Bosch is a partner with Nissan and Diesel Kiki. The joint venture is called JECS which is the brand of all the electronic sensors and actuators on our J.

[yodawill2000]

You can put a breaker bar on the crankshaft bolt and see if the engine will do 2 full revolutions.be sure all fuel is out of the cylinders before attempting that.You might try that before investing in the new injectors.Hopefully there's no damage.

[dcunningham]

I will check these two sites out .

Thanks for info.

[dcunningham]

Okay cool will try and see what happens I will let you know how thing turn out once I get it all back together.

Installed new injectors in car engine sound really good now. But one problem if the car sit there and idle for five minutes it starts to smoke like a freight train. Any idea own what might be causing this to happen now I never had a smoking problem with the car before I done this work?

[yodawill2000]

What color is the smoke ??And the smell ??And is it coming from the tailpipe ??

More data please !!

[dcunningham]

The smoke look pure white to me but it smell like oil burning just took on test run when I step down own it really smoke bad then.

Temperature is normal not overheating or anything.

Yes it is coming out of tail pipe

[yodawill2000]

Oil level OK ?

White is usually Water.

[dcunningham]

look like it might be over filled and smell a little like fuel.

How is the coolant level and no vacuum, fuel or coolant hoses are swapped?

[dcunningham]

Coolant level is full all fuel and vacuum line are hooked up correctly.
