Welcome to Nico !!

First step would to be pulling the codes from the ECU.
There's a sticky in this Forum on how to do that.

[95_J30prechange]

well i can pull the codes but the check engaine light is not on so ther is no indication that there is a problem

[yodawill2000]

The sticky shows how to do it at the ECU.
No cables needed.

What type of spark plugs did you install ??
Also there's a few things that wont cause the check engine light.
Mainly the Knock Sensor.

[95_J30prechange]

okay but the thing is it doesn't say there is a problem...... the ‘‘Check Engine’’ light is not blinking or on at all!

[yodawill2000]

I understand but there's a MILLION things that can cause this.
MAF , Fuel pump , The list is very long.
When it was running, did it shake at idle ??

[95_J30prechange]

yes the idol would jump at times.
when driving the car it felt like it was going to stall when i was'nt accelerating

[yodawill2000]

Cleaning the MAF would be a good start.
Will it still not start ?

[texml69]

might be flooded if it still wont start hold it at WOT before cranking on and keep it there while cranking on it if it is flooded it will take a little bit to start

If there is still water in your gas you will have to keep taking the fuel filter off, pouring out the water, and reinstalling it. No need to buy a new filter each time, just pour the water out. The same thing happened to my Infiniti G20 and I had to repeat the procedure several times until I got all the water out of the gas tank.

First time out racing our J we had some, no lots of rain get sucked into the airflow meter, car would barely run, sorta like described, for 10 min until it dried, this happened 2 times before we figured it out.
When we returned home we could only duplicate the symptoms by disconnecting the AFM.

Do you have access to a known good one to tryout?

[Amays U G37S]

I think that crappy gas you put in caused an injector to go out. Test them.

Also, when you stick in crappy gas, you put in FUEL STABILIZER, not Fuel Cleaner.

The best way for us to help you is too pull the any stored code(s). If a fault occured, it would be stored in the ECU. What your describing can be caused by a number of different things. Pulling the code(s) helps us eliminate those that do not apply to your situation.

[95_J30prechange]

Thanks all of you I will pull my codes now... I an getting through my injectors but I'm not getting a spark from the plugs

[95_J30prechange]

How do I get to the ecu?

[yodawill2000]

Its behind the kick panel on the passenger side.

[95_J30prechange]

Okay

[95_J30prechange]

Okay I took off the front kick panel. Bu I don't know what the ecu looks like?

[95_J30prechange]

okay i narrowed it down to one of my ignition coils or my ICM!
but i dont know how to test my coils to see if one of them went out?
can anyone help me out!

[yodawill2000]

If you have no spark to all the plugs then its not a single coil.
If it IS just one cylinder missing then move the suspected coil
to a different cylinder and see if the prob follows.

[95_J30prechange]

No spark from any of them!

[95_J30prechange]

Would the crank anckel sensor cause my spark plugs not to fire?

[driverdriver]

What are you using for spark plugs?

Make sure you are using OEM. They're NGK platinums.

Sparkplugs that are non NGK platinums are well known for creating all sorts of weird issues in the J30 engine. Ditto for non-OEM alternators.
