Hi,
Yesterday afterwork, I went to start my J30. I had a very hard time starting her. After a few tries it started, there was a strong gas smell and I notice white smoke, not gray, comming out the back.
The car had no power. It was like the car was running on 3 cylinders. I also notice the white smoke. I checked the muffler and I notice water on the tail pipe. I checked the oil and the radiator. There was no mixing of the fluids. I checked the air filter. I fulled up the gas tank and added dry gas.
After some time the check engine light came on, I drove it home.
About a month ago, I did some preventive maintance 113,000. I replaced
Both Oxgen sencorsPower Transister ModuleFuel FilterFuel PumpAll belts and hosesTrans fuild flush
My J30 has 115,000 miles. I has been running great up until know.
Any help would be greatly appreciated.

Hard Start, no power, Check eng lite:J30
sounds like a bad injector or FPR.
get the codes.
if it is an injector, you can check the electircal resistance of each injector to determine the bad one, or you can use a stethescope and check manually, however this will just show when the injector is dead.
more likely it is leaking, and still might be outside ohm range.

ususally it can be done without removing the plenum, but it might be a good idea to take it off and replace all the fuel hoses, as preventative maint.
i would recommend new ones, so there are no worries, although then it is likely that the new one will be fowing differently than the other 5.
you could get a used one, check the ohmage, and then have all of the injectors flow balanced.
or you could just get a used one from ebay and throw it in there.
it just really depends on how far you are willing to look ahead, and if you want to accept the fact that you might have to go in and replace the replacement.

I tried getting the Diag codes. The battery was completely dead. I did a load battery tester, it failed. When I use my battery charger, it tells me it is fully charged. I had to replace the battery.
I replaced the battery. The car was hard to start. Once started, the engine ran a little rough. I let the car warm up. The engine light is no longer on, but the power is still weak.
Once it was warmed up, it was easier to start, but it still has no power. I also notice that gasiline/vapors is comming out the muffler system.
Thanks for the help.

Well, I took it to a mechanic. It looks like I might have a blown head gasket. He spoke to the dealer and he told him that he nevers sells head gaskets for these motors.
He will confirm it on Monday. The strange thinig is the car was work fine right up to this point, no overheating or nothing.
Just in case it is the head gasket, would it be better to install a newer used motor or fix the orginal one? Where would you recommend getting a newer used motor?
It is sad, because I have been so religious about my J30 maintence. Things happen.
Thanks.

Last Friday, I had a tow truck come to my house and take my J30 to my mechanic.
Before the tow, the tow truck driver asked what was wrong. So, I started the car and I explained my problem. The car started without a problem, but it ran rough. I stopped the car and the tow truck took the car.
When my mechanic tried to start the engine, he couldn't even turn the engine over, hydro-lock. It was like the engine was seized, which could be from water in the cylinders. He removed all the spark plugs and found, yes, there is fluid in two of the cylinders, which is causing the engine not to turnover. The fluid wasn't water, but gas. My head gasket is fine. I had two cylinders filled with gasoline. The Gasoline was causing the hydro-lock.
I will be ordering all six new fuel injectors, two plenum gaskets, new spark plugs (old one had 45,000) and all o-ring injector seals. Since we are removing the plenum, what fuel hose should I replace? Is there a description or would the dealer know what I am talking about.
Believe me compared to a head gasket, I am so happy to be replacing all six injectors, instead of another engine.
I am still a happy J30 owner. This is the first major issue I have had with my J30 and she didn’t leave me stranded either.
Thanks everyone for all your help and good catch on the injectors.

Frank

Where I can get infiniti parts from a dealer at a discount?
I purchased the parts from Tom Ryan at Infiniti of Lisle, and he said he didn't do the club discount anymore. He said he would do it one last time for 20% of list.
I need another source for new infiniti parts? Anyone have more sources that give discounts?
Thanks. frank

Well, the car is at the menhanic. He replaced all the fuel injectorsTHe two front cyclines (1 & 3) on the passenger is still misfiring and white smoke is comming out the back.
I didn't replaced the power unit. I lasted to shree to be that guy
Please any help. would be greatly appreciated.

Did he replace the plugs? Sounds like you had a fuel leak--plug(s) are all fouled up now, and maybe the O2 sensors too. You never stated what the smoke smelled like. Sweet? Rich fuel? Sometimes things get better with some aggressive driving to burn off the carbon. Probably a bad injector seal, but maybe not. I would have the plugs replaced and, at the same time, do a compression check. Number the plugs as they come out and inspect them. Doesn't take long for fuel leaks to start to wear down a cylinder.
Thanks for the quick replay. We replaced all the injectors and new seals. We also installed new OEM spark plugs and O2 sensors. The smoke smell is gas. NO Check engine light.
They did a compression test. It's OK. They our testing the signals to the coil pack and injector to see if it is a Power transistor unit.
You can't drive the car down the street.
Thanks again for your input.

If you still have white fuel smoke in the exhaust, then my opinion is that you still have a fuel leak. It is easy to pinch a seal. Also, I don't know if you trust your shop, but I have actually had the experience of paying for parts and labor that were never installed. Imagine my surprise when I pulled out spark plugs that should have been replaced, only to find that they still had my initials on them. You have to have the rail pressure checked to see if it is leaking fuel after the car shuts off.
At this time, they have given me no reason to mistrust them. The problem isn't fixed and your right I think I have a fuel leak. and or electrical problem with cyclinders 1 & 3. I will call him ask about get the rail pressure test after the car is shut off.
Plus I always ask for my part after the repair. I check my markings too.
Thanks man. I appreciate your help.

The problem turned out to be a connector problem with the Power Transistor unit, which is located at the top rear of the engine. Use Di-Electic Grease on the connectors.
A mod from this site, NISTECH, located the problem and help my mechanic fix the car.
I want to thank everyone for your efforts and especially NISTECH. My mechanic said he was awsome.
Thanks again NISTECH

I am having the same sypmtoms that you describe (and they seem to have started occuring around the same time). Do you have any correspondence from the moderator regarding this unit? I will look it up in my manual tonight. Currently the shop mech is telling me I have a bad ECU, but I can pull codes from it no problem - they are Heated O2 Sensor, Injection system, and can't recall 3rd but the codes given were 12, 33, and 51 I believe - will check notes when I get home tonight. I just can't imagine spending the quoted $500 to replace ECU if that is not the problem.

The codes I mentioned were correct. But now it seems I'm in a pickle. When I took the car to this mech it was at least driveable. The day after he looked at it I was going to take it somewhere else for a second opinion but it wouldn't go over about 10 mph and only in 1st gear. My suspicions grew but I felt "stuck" there so I told him to go ahead and order the part (you know how some people are just soooo convincing?). So now he has the part shipped in (received it just this morning right when I called to say I wanted to cancel the order - and yes I marked my part so it was a different one). Well from what I've heard here and also from a buddy who works for Lexus the ECU's typically don't just "go bad" and this guy has not *guaranteed* that the replacement will fix the problem so naturally I'm balking at this point. It has been 3 days since I told him to go ahead and order the part - now I'm asking him to ship it back but I'm betting he's going to tell me that I have to pay for the part now that it's in. Do I have any rights in this matter? Help! I feel like I'm being taken to the bank to sign my account over to this guy :P
