It wants to start... I need some answers please

If your following my other post then you have a clue whats going on. Well changed the Fluid, Spark Plugs, Dist, Rotor, Plug Wires (i dunno why), Oil, Oil Filter, cleaned all Electrical Connections, Took off the Intake cleaned it out, Cleaned the Ports, and grease all electrical connections good. Now I tried to turn the sucker over it just keeps turning and turning and turning... with the Valve that connects to the Air Box Un-Done ( the rubber hose on the Valve Cover to the Air Box) It shoots out WHITE SMOKE. I can't really tell if I'm getting gas... but I know I have spark from the Coil to Dist and Dist to the Spark Plugs. WHAT COULD BE THE PROBLEM? Do you think if I pulled it behind a car and popped the CLUTCH IT MIGHT START?

Re: It wants to start... I need some answers please

Popping the clutch ain't gonna help. If it won't start in neutral... it ain't gonna start at popping at 25mph.

Try:

1. Pull the coil wire.
2. Turn the igniton to START.
3. Let the engine cycle for about 3 - 5 revs.
4. Turn the ignition off.
5. Pull the plugs.
6. Examie them.
7. If you are getting fule then the plugs will be wet and smell of fuel.
8. If the plugs are dry then the injectors are not working.

Reconnect the coil wire.

9. Spray soime starting fluid into the Throttle Body.
10. Reattempt to start the Jeep.
11. The starting fluid should be sucked into the combustion chamber and compressed with the air.
12. If there's spark the engine will attempt to run.

You've just figured out if you're getting:
a. Fuel.
b. Spark.
c. None of the above.

Now determine how weak the spark is, if you've got one.

LEVE... guess what worked... popping the clutch? Its 5:11am here... been driving my Wrangler around town with a Freakin Lawn Chair on the Body since my Seats are out. I pulled the Jeep behind my Cherokee with a buddies help and popped the SUCKED AND BOOM! Fired up I let it run for about two hours now... Think everything is cleaned out! The FREAKING JEEP SCREAMS NOW AFTER CLEANING THE INTAKE AND PORTS AND THROTTLE BODY. I MEAN DEAR GOD. BURNING DOWN SOME 33x14.50s with a Four Banger! Thanks for the help!

I\'m confused. Someone enlighten me!

Now this is interesting!

Why did it not start with the starter was able to spin the engine? I'm <font color="orange"> assuming </font color> it had spark and fuel. So what would make popin' the clutch start the engine when the starter couldn't?

Dang, I hate being wrong, and I hate being ignorant. [img]images/graemlins/mad.gif[/img] Someone <font color="red"> enlighen </font color> LEVE! [img]images/graemlins/blush.gif[/img] [img]images/graemlins/blush.gif[/img]

Re: I\'m confused. Someone enlighten me!

I didn't look at the other thread.

Possibly one of 2 things - wet plugs - fouled - even when
putting in new dry plugs the cylinder's so wet it instantly
wets them down too.

Or - and if it's hard to start next time it's cold - the resistor
bypass may not be working or disconnected. Then the lower
voltage from spinning the starter also starves voltage to
the ignition.

Or - ignition switch - no ignition during cranking?

Or - something's loose somewhere in the wiring - the movement
from towing and "popping" was enough to jiggle the bad
ignition connection - tough to find - but it will happen
again if it was that.

Tow truck driver's trick for getting a fuel wet - flooded -
engine started --
Pull the coil wire out about 1/4 - 1/2" from the coil or
dist - leaving an extra gap, lengthening the arc, but not
killing it.
Start it up - it'll run bad a few moments but will start
to straighten out. Then you can slowly push the coil wire
back in till it runs fine again.

Not magic - the extra gap makes the required voltage go up -
and since the voltage pulse waveform risetime is steeper at
that point, it "blows" the crud off the plug.
Same principle that MSD uses with their Capacitive Discharge
- a steep risetime.

You've seen the "Spark Intensifiers" demonstrated at swap
meets and fairs - same thing as gapping the coil wire - the
thing fits in the dist tower - cut one in half, you'll find
there isn't anything in it besides an extra gap of about .035.

It works at low R's and no load, but not high speed or any
kind of load. Those things prove PT Barnum was right.

Re: I\'m confused. Someone enlighten me!

I think all the wiring was fine... once I road it after I popped the clutch the engine fires right up. Just woke up and started it right up. So I think the extra torque put on the engine to start made it turn over and burn out all the extra [bleep] that was in it. I think the little water helped clean the engine out.
