300zx z32 Vg30de WONT turn over.

[Duce40sx]

Okay,

I did a recent tune up: new injectors, New Knock sensors, etc.

Today I plugged everything up.

I cranked the engine, and it sorta cranked up.

I Crank it up a few more times afterward, It seems like something is LOCKED up.

1. Turn On key................CLUNK!.. Turn On Key................CLUNK!

I removed the Starter, Hanging off the wires, turn on the Key and it SPINS.

Put back the Starter, Turn key on............CLUNK!

What's up?

[onelessissue]

i bet you put a bad injector in there and it stuck open and hydro locked it up

[Duce40sx]

What do you mean by that?

I put SIX (6) New injectors in it. with 6 new injector harness.

I just took out the Starter.I use a socket and Turned the Crank (in Neutral), but it will only let me turn about 45 Degrees.

It locks up when I turn it clockwise and also counter-clockwise.

WTF! Damn! So frustrated.

[adl16v]

why did you remove the starter anyways? was it fine before you did the tune up?

[Duce40sx]

It sounded like the starter died or jammed.

I drop a lot of nuts and bolts, I think I've managed to recover all of them.

I am so frustrated. I mean, It cranked up the first 3-4 times.

Then it just Jams, and "Turn on car...............Clunk"

I turn the Crank, and 30-45 Degrees counter/and clockwise......THEN CLUNK! It's not FUEL, AIR, OR SPARK, THE CAR DOESN'T CRANK! STARTER SEEMS TO WORK, BUT SOMETHING IS "CAUGHT".

Besides, the possibility of a Nut/Bolt in the Timing Belt, Is there any other common errors that may keep the Crank from turning?

[freakonaleash1187]

Sounds like you have a seized motor, which I know you don't want to hear after replacing all the injectors and everything, but sounds like you will either have to tear your engine down or buy a new engine.

[Duce40sx]

It ran 2 weeks ago. It can't be a bad motor. I replaced all new parts and gaskets. Plus, i cleaned it out even better than it was before.

I Know That people have drop bolts in the timing belt and other places.

I will take out the Timing cover and find anything that may be in the way.

Seized motor? Can you justify why?

1. The car was running quite good 2 weeks ago. 2. I replaced the Knock sensor, gaskets, injectors, and harness.

** During the Re-Assembly, my friend and I dropped various 20-30 nuts/bolts/tool bits, down in the motor. We manage to recover most, and hopefully all.

3. It cranked up a bit and then after that, it seemed that something got stuck in the Cycle. And now that Starter or the Crank/ pulleys/ or alternator, seems to be caught on something.

[nghtrain88]

the most obvious would appear to be the various nuts/bolts/tool bits floating around in there...

[Canyoncarver]

First, quit using the starter to try and turn it over.Second, Use a socket on the crank pulley bolt and try to turn it over by hand.Third, if it's locked, remove the sparkplugs.Fourth, remove the fuel pump relay, fuse, or otherwise disable the pump.Fifth, crank the motor over by hand, and watch for fuel coming out of the sparkplug holes.Sixth, Just click the starter a few time to get the motor to turn a couple of revolutions.Seventh, crank the motor over continuously till no more fuel is spraying out of the sparkplug holes.Eight, Find the damaged injector o-rings. This will usually be the cylinder that is spraying out the most fuel.Ninth, with the sparkplugs still out, crank the motor over and watch for more fuel spray.Tenth, either repeat the above if there's fuel coming out, or reassemble and change your oil before starting the motor.

In short, it's rather common to damage an injector o-ring at instalation. The motor is most likely fuel hydrolocked. Hopefully you didn't bend a rod.

[Duce40sx]

When a car is hydrolocked....would the crank be dfficult to turn?

I mean, I turn the crank by hand and it goes CLUNK!,

Turning it is easy, and when it gets to a certain point, it just CLUNKS tight.

Hydrolock would just Build pressure and make a gradual stiffening of the cylinder, but this goes easy and then a sudden CLUNK.

This VG30de Is a piece of shiet man. Worse designed engine ever. I should just put in a 2JZ motor.

If your z32 are fairladies, mines being a total B1TCH

[izmyttz]

get one of these...it will def help turn it over........lol jk I know i know..not helpful..it is the first and last time being a smartass.

That would be JDM tyte! Jo would have all da bitchez if da 2JZ was in their! Dat is de sickest motor evars!!!!1!!one!!1 Notin can compare to da pimp 2JZ!

[nghtrain88]

haha ^^ where can i get one of those?

[Canyoncarver]

Pull the plugs and see if it turns farther. Otherwise sell it and by a sentra.

[evildky]

I have a hard time imagining the injector seals put in so poorly that it allowed enough fuel to pass by the top seal and then past the bottom seal to hydrolock the motor, if it were so poorley installed I'd think you'd notice, back to the issue, what all did you do to the car since ti was running? did you pull the timing belt? is the starter complete? didn't drop a chunk of housing or a gear inside the bellhousing?

[Canyoncarver]

It's rather common on the z32. It might be due to a lack of experience by the people doing the work. Instances of bent connecting rods from the hydraulic lock have occurred. The poster here can do as he likes, or he can listen to some advice.

whatever :shrug

[evildky]

if someone can put screw up injector instalation that badly, they should stay away from the toolbox

[Booztd 3]

My initial thought was that Duce40sx should take the car to someone that actually knows what they're doing.....

[freakonaleash1187]

Agreed fully. I hate it when people come around asking for advice and then when they get legitimate advice, they don't take it.

[lilskirk23]

ok heres my question... i would think that if you dropped a nut or a bolt while you were working on your car.. stop immediately and find it... dont wait until later to try to find it. idk maybe its just me but it seems more logical to find it immediately so you know youve found each bolt. spend the $5 and buy yourself a pickup tool with a mirror so you can find anything youve dropped and get it (not trying to be sarcastic).

my advice is to take your time and take everything back apart to make sure theres not anything obstructing any moving parts of the car. if youre still having the problem... take it to someone who will take care of it for you. at this point its not worth youre time.

[Duce40sx]

I agree with you guys.

1. My friend and I do, recover the bolts or nuts we lose, Immediately. And after hours of not finding a particular one, we move on.

2. Yes, if we knew what a biatch this VG motor is, we wouldn't have bought it.

3. It was a 1990 Clean Title and paint, interior, was original. Hence, it Seeeemed like a good deal. And heck, it was Running fine, before we threw the code:

51- injector circuit34- Det Sensor circuit.

I have an 240sx KA24de right now, and we are selling this "Fairlady" to get what we should have gotten in the first place, an S13.

In conclusion, Live and Learn, And I would hope you guys agree with me that the VG30de is OVER-designed, or just SUX.

1. Must take Plenum Runners to do about Everything.2. Knock sensor in the middle3. Coil Packs when they should just used wires and an Exterial Coil4. WTF is that Balance bar there for? Useless. Can't even get to the 2 back SpaRK Plugs for goodness sake!

5. Beautiful Looking car, bad interior, bad motor.

6. In not a 300zx specialist, but, if a car is tight and spacially difficult to work in/on, it's rubbish.

A real Gold-Digger~~ Just washed her, just how we bought her, 2 weeks ago.

Anyone WONNA BUY A 300ZX CHASSI? CLEAN TITLE! NO ACCIDENTS. Everything Original!

Should have just made a Damn RB30dett or something. SR30DETCA30DET or something!

[freakonaleash1187]

1. I bet you did spend hours trying to find bolts.

2. You should of done your homework, plus, you just have to know how to work on it

3. Problems happen on 18 year old cars.

4. Coil packs FTW, balance tube does what its name implies, it balances the air between the two sides of the intake, if you would actually think about it, the two sides of the intake never actually connect with each other, so there needs to be a place where the air can balance.

5. Bad interior and bad engine? You are just being ignorant.

6. So any car that is hard to work on is rubbish? LMAO! So I am guessing Ferrari's, Porsche's, etc. are all rubbish because they are hard to work on?

My conclusion: Sell your Z, get as far away from the Z world as you can, you don't belong here.

VG30DE(TT) FOR LIFE

[Duce40sx]

You're right.

I will only buy cars that have efficient engines:

Honda Vtec'sNissan KA SR RBToyota JZ's

Now I can knock it cuzz i've tried it. VG30DE RIP. Thanks for the Help though. And yes, Compared to the motors above, the VGDE is Rubbish.Fine, it's rubbish not because it a tight space, it rubbish because it was poorly or overly designed.

1. Det sensor could go somewhere else instead of the damn middle of the motor.

2. plenum runners could go III__ instead of I I I III I I I

3. Or Intake runners comming straight out to the front bumper.

4. Use the Ignition wires and external Coil instead of Packs

Life's too short. Imma buy a Twin Turbo Hyundai.

Peace out.

And LASTLY and Most importantly!

5. What's up with Mitsubishi parts in a NISSAN? From rivots to crank sensors. MITSUBISHI.

Explain that? I bet the same dudes that made the 3000gt designed the 300zx.

As Jeremy Clarkson says: "Nissen 300 ZED X is RRRubbish"

[mtcookson]

Just a little fyi... before the VQ35 started getting worked on, the VG30DETT powered the fastest Nissan's. VG > RB

[Duce40sx]

Hey,

All this time im talking about the VG30DE not the TT.

Well, no matter how good the VG is, I will leave it be. I am not a fan and you guys are. Thats fine, Thanks for the help.

Later.

[mtcookson]

Yeah, comparing the DE to the TT is definitely a little unfair. To be honest, I would personally take a VG30ET as I believe they're slightly more reliable but the VG30DE(TT) can take a beating. The most important thing though is to maintain them properly. No matter how strong they are, if they aren't maintained properly they'll fail. Some just take more maintenance than others.

From what I've seen, sometimes you get good Z's and sometimes bad. I bought mine with over 200k miles on it and it has worked great until I pulled the engine for a swap. A guy I know online bought one with much less and has been having quite a few issues. Its sad to see stuff like that happen to Z's as they can be fun cars... but hey, 240's can be just as fun. Be sure to come back when you get the 240, post some pictures, and keep us updated when you do mods and such.

[Canyoncarver]

Hey,

All this time im talking about the VG30DE not the TT.

They're the same motor. Since you're in L.A., I'll give you $500 for it and take the POS off your hands.

Out of all the crap you have posted, I only see one point that makes sense, and its the point that you made it is a little over-designed, but I love that. Nissan set out to make the best damn sports car with the Z32. You just can't handle complexity, so you should just stick with simplicity, its easier.

[Duce40sx]

Hey, the Z32 has an awesome look to it. I just had an old and bad motor.Shiet happens.

It is an older car, so things wear out especially the Plastic and rubber parts which get brittle.

Here's my Infinity S13.Got the G35 leather seats. It's practical and I can say im the first. Im a great IMPROVISOR, and If I can't make it work with sufficient time or money, to me it's too much work for me.

Hey, If I had a VG30DETT and it ran great, I wouldn't be complaining.

yes the VG is over engineered, and a huge PITA to work on, most FWD nissans are a PITA as well, but I gotta love me some coil packs, nothing wrng there, I plan to swap edis onto my L6, might not be "coil packs" but at least is's a "coil pack" and you'll find mitcu electronic's on hondas and just about every import and some american cars as well, I used to have a mitsubishi home stereo reciever with a touchpanle volume that was way ballin for the 80's
