3rd time the charm?

[TurboSauce]

Ok so I posted this in all the right sub-forums and it's getting no attention whatsoever.
basically:

this may be much to ask but, i wana know if you can tell me what's the problem with this engine[youtube]http://www.youtube.com/watch?v=S2UE5ama7yc[/youtube]

[raremotive]

did it stop running after collision? Does it come equipped with a fuel shut off inertia switch?

[King Ranzo]

What he said.

Also, just out of curiousity, what car is this?

[TurboSauce]

No it was still running, it sat for about 2 weeks and choked.
and
I doubt that it has one of those, but there's a slim chance it might.
it's a vq30det, and it's a 1997 y33 nissan cedric Super JDM y0.
there aren't ANY fsm's for this car
well any in english anyway

[TurboSauce]

oh and after the third attempt to get it to turn over there was a slightly strong scent of gas in the air.
and i can't rule out the possibility of it being just wiring, rat poo and non starting engine makes turbo ANGRY boy.

[King Ranzo]

I like the wiring idea. If there was a rat in the engine bay, it could've chewed through some wiring and eff'd something up.

I rub bacon grease on all the important underhood wires before I park my truck for any length of time.

what does that do?

[King Ranzo]

It attracts Jesda. Jesda then defends the car from any animals.

[s0m3th1ngAZ]

Yes...because he eats rodents.

[TurboSauce]

inb4 Jesda

Bump for interesting...

Well, battery seems fine, starter seems fine, you're smelling fuel. That leaves one possibility: spark. Have you checked for spark?

funnier thing, ALL spark plugs were changed the day before the accedent

[MinisterofDOOM]

Plugs don't mean jack. If they're not getting voltage, they're not going to spark.

Yep, Im with doom. Check to make sure you have a bright blue powerful spark.

It sound like you have very week spark, thats why it kind of kicks over, but never starts. May need a coil, ignitor, or possibly the cam/crank sensors.

Are the plugs fouled?

[TurboSauce]

ok, i'ma let you guys in on a very well know seecret. i'm a noob to cars. so the best i can do is take it apart. and take pics and show u guys.

[TurboSauce]

after that i hardly know what is what.
i know general knowledge about cars.
and to answer you ian, i'd have to check, which means i'd need tools, which i don't have.
we have tools, they're just not home. they're in panthers car. ( mechanic)
but i sorta want to do this on my own and not sit back and watch, so, i'm over complicating stuff.
by alot.

oh and also, after the enigne was cranked, all power was lost.
for about 3 seconds.
i think it is something to do that's electrical.
which makes it all the more difficult.

Hahaha, I think we gathered that much.

Well start by removing all the uneccesary plastic covers so you can see the wiring, injectors, and coils on the engine. Check for any loose connection, or chewed up wiring.

Does this engine use a single/dual coil with plug wires, or does it have individual coil packs?

Have you checked for any DTCs in the ECU?

Pull one of the spark plugs out. Check to see if is wet with fuel, and/or black with carbon. Then put said plug into wire/coil, and place it on a good ground, then try to crank the car (having a friend would help). You could even have the camera film the spark. Spark should be bright, and blue in color, and it should be steady, not erratic. If its purple, dim, or nonexistant, then you have found your problem.

I would check spark on at least one plug per bank, if not all the plugs.

[TurboSauce]

ok, i will keep you guys updated with pics when i do it. thanks for the idea.
when my brother comes home with the tool kit ima get cracking.

Ok, i've had this same issue before a couple of times with my old 92 300ZX. There's a harness on the front of the engine, I don't remember exactly what it goes to but if I remember right it was on the passenger side front of the engine, near one of the plastic covers. This harness wasn't getting a good connection due to wiring issues so check and make sure the wires are not burnt or anything. I believe the harness was going to the crank or cam sensor. After that just make sure all of the harnesses are making a good connection and show now signs of corrosion. This may not be related to the issue but it sounds very similar to the problem I was having. Also make sure your MAF has good connections as well while you're at it. I spent a whole week chasing down this problem before, as it could appear as a handful of different things, but a friend that did a lot of electrical work on cars helped me track it down to that. Sorry to not have a better description of everything but this happened 4 years ago, Hopefully this helps though!

It's a VQ30DET, so it's COP.

Turbosauce, check for spark by having someone crank the engine while you hold a (or each, thought from the failure to start it seems like it'll be all or nothing) plug next to the intake manifold (a good grounding point, so you don't get shocked yourself, and to provide an easier to see arc). Just be careful; spark plug shocks kind of hurt.
