Help!!! one of the most complicated problems! 1989 240sx

You are a very angry individual.

I find him funny.

:bowdown:

No i am not
i just posted to tell whoever thinks that a broken motor won’t turn over…

Actually even a broken strater TURNS over.
It’s got two feeds to it. One to pop the little pulley with teeth out and one to rotate it
It will turn the motor but very slowly

Ok ™

Here’s a list of problems that could go wrong if your car doesn’t start !

Bad fuel mix

You are out of gas, so the engine is getting air but no fuel.
The air intake might be clogged, so there is fuel but not enough air.
The fuel system might be supplying too much or too little fuel to the mix, meaning that combustion does not occur properly.
There might be an impurity in the fuel (like water in your gas tank) that makes the fuel not burn.
Lack of compression - If the charge of air and fuel cannot be compressed properly, the combustion process will not work like it should. Lack of compression might occur for these reasons:
Your piston rings are worn (allowing air/fuel to leak past the piston during compression).
The intake or exhaust valves are not sealing properly, again allowing a leak during compression.
There is a hole in the cylinder.
The most common “hole” in a cylinder occurs where the top of the cylinder (holding the valves and spark plug and also known as the cylinder head) attaches to the cylinder itself. Generally, the cylinder and the cylinder head bolt together with a thin gasket pressed between them to ensure a good seal. If the gasket breaks down, small holes develop between the cylinder and the cylinder head, and these holes cause leaks.
Lack of spark - The spark might be nonexistent or weak for a number of reasons:

If your spark plug or the wire leading to it is worn out, the spark will be weak.
If the wire is cut or missing, or if the system that sends a spark down the wire is not working properly, there will be no spark.<----Ignition coil
If the spark occurs either too early or too late in the cycle (i.e. if the ignition timing is off), the fuel will not ignite at the right time, and this can cause all sorts of problems.

Replaced ignition coil/new battery/fuses/alternator belt=I am sucessfull and proud of making my car run, excellence for a 16 year old now I’m off to stage 2 what’s the next problem?

For fuel to go bad you need a really long time
IT"S NOT AS EASY!

Usually when out of gas the FP makes a diff sounds and you can’t hear the fuel in the lines.

NOT enough air would be detected and even then PARTIAL spark would be present!

If it was supplying too much and he let the car overnight and tried it again the next morning it rules that out.

Too little fuel?? I don’t know how that can happen on start…unless he has a ground issue. If that’s the case he should check for impulse being sent to the injectors.
NOIDS are the tool to have for this.(plug crank and check for blinking light)

Impurity would cause it to sputer around but still fire once or twice around.

Lack of CR is not going to be the same on all cylinders. Even if it is it would still start but the power would be crap.
There is enough pressure build up for it to work
But you would smell that as burning oil like no tomorrow

Piston rings ARE in no way a reason why your car wouldn’t start. There simply isn’t enough space they can cover to escape all the pressure being built.
Intake valves AGAIN they don’t cover as much. If they weren’t seated properly BY HUGE marging YOU would heard piston hitting the valve.

Hole in the cylinder can accour it to run ON 3 cyl even though it would still fire and produce very low energy levels. IT IS no cause

spark might be a factor but that’s easily checked.

One check for spark(remove wire see with a screw driver)
If you got no noid, crank car for a while
remove spark plug check for wetness/inspect PLUG(there is fuel if plug is wet)
Use some quick start before the TB if you can hear it sputter and fires a bit then it’s your fuel/fuel delivery
If you got AIR FUEL SPARK and still no fire(check timing, starter) pretty self explanatory

I think you own the guy an apology for acting so rudely towards him even though YOU WERE wrong in your google INFO

If the car was turning over, why would you need to boost it? Again, if the engine was seized, why would it turn over? Your car will take 4 “bottles” of oil to fill from empty. You don’t need an “expert mechanic,” your problem is likely of the most simple in nature, you just need someone other than yourself to look at it. Read: someone knows something, anything, about cars.

Seriously, give your car to a professional before you really do wreck it, or hurt yourself.

Poor car indeed.[/quote]

OK the more i read of your stories the more i FEEL sorry for you…

'If the car was turning over, why would you need to boost it?"

Now you sure you don’t want to rephrase that one again?

You don’t know how the battery was under load!

Ok buddy, I’ll think about it.

In the meantime you should go back to writing 3 pages as to why his suggestions are wrong instead of solving anything, which, like I said, is a waste of time until he learns to better describe his problem.

You have a CA? What’s done to it?

well when you don’t know then i guess you should sit in your corner and call the guys from whoever did your car to answer for you since you are not capable off…
He came with a question and you backfired at him.
So what if he is not as inclined as you are when it comes to cars(NOT THAT you are since you proved yourself …ummm a …i don’t want to use profanity because ppl who don’t know take my suggestions to them as the wrong way)

You have a CA? What’s done to it?[/quote]

i have 3 ca’s
which one would you like to know?

Whichever one you have built the most?

Care to elaborate?

this is jsut stupid and off topic now.

pm him if you have any questions…
