    I WILL TRY TO TAKE THE MIXTURE CONTROL SOLENOID OFF AND CLEAN ANY DEPOSITS AND SEE IF IT APPEARS TO BE WORKING.. I HAVE NOT FOUND ANYONE WHO KNOWS HOW THIS DEVICE WORKS AND WHAT IT DOES EXACTLY.

  • Richard Scordino May 11, 2010

    what you are looking at (depending on carb & engine) could be the mixture control solenoid. I don't have any info on adjustment or repair on that, but I'd first try just removing and cleaning it to see if it's binding from deposits etc.

SOURCE: Engine will crank but will not turn over

Do this, take the top off the carb, being careful not to damage the gasket. Then take some carb cleaner and clean out the bowl and floats. Remove the needle valve and clean it out. Put it all back together and filling the bowl with carb cleaner. Start it with the starting fluid. Once you run the carb cleaner through it, it should start to run on it's own. Whatever you do don't shut it off for about 20-30 min unless you have to.

SOURCE: 89 JEEP WRANGLER... GAS IS GETTING TO CARB, BUT

If the gas flows all the way to the carb but no gas is spraying, than there is a clog in the line, or the nozzle, or you may have a dirty or debrit in carb itself.

SOURCE: 2007 Jeep Wrangler Unlimited Crank-No Start. Replaced FP.

Hey Tim take a look at this, will this help ?
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if
equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also
referred to as the Sentry Key Remote Entry Module (SKREEM).
MODELS:
2007
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the
remote keyless entry (RKE) system will not operate. This condition may be due to an
electrostatic discharge (ESD) from the ignition key into the Wireless Control Module
(WCM), causing the WCM to electronically lockup. This condition may occur more
frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is
more easily produced. This condition is corrected by the replacement of the WCM
DIAGNOSIS:
1. With the condition present (i.e. the vehicle in the no crank / no start condition), connect
the StarSCAN® scan tool to the vehicle.
2. Turn the ignition switch to the “ON” position, and power up the StarSCAN®.
3. If the WCM is electronically locked up, the StarSCAN® will display the WCM as being
“off bus”.
4. If the no crank / no start condition is present, and the WCM is “off bus”, then reset the
WCM by temporarily removing the IOD fuse (with the key out of the ignition switch),
wait for 10 seconds and then reinstall the IOD fuse.
5. With the IOD fuse reset having been performed, verify that the vehicle will now crank,
start, and run.
6. If the condition is temporarily corrected by performing the above steps, and if the part
number of the WCM is earlier than the part number of the WCM listed in the part
reference table in the Service Bulletin Parts Required Section below, then perform the
Repair Procedure.

SOURCE: I want to spray carb cleaner in my 89 Jeep Wrangler:

If you want to clean your carb, just remove the air intake, spray the carb while holding the throttle at about 2000 RPMs. It is ok to spray the out side area, but not necessary. Be-careful that you keep the carb cleaner away from a hot exhaust. I have had a couple of time over the last 30 years where a fire erupted. If it does, don't panic, it is a cool fire and you can usually blow it out.

Not getting gas to carb


It could be. Since you have a carburetor, you must have a mechanical fuel pump on the engine? Only some imports with carburetors had an electrical pump.

If your filter is in the line just before the carburetor, take the line off at the filter, then crank the engine over to see if the pump is working. Mechanical fuel pumps will pump gas when the engine is cranking or running. Use a jar or can to catch the gas. If pump is working, fuel will come out in small spurts. It's not under high pressure- carbs don't need high pressure. If no gas comes out of the line, you probably need a new fuel pump. If the pump is working, it could be the filter, but could also be the needle valve and seat at the carb's fuel inlet. Sometimes they get stuck closed and won't let gas into the carburetor.

How to prime carburetor on 1988 Toyota tercel 1bbl


Normally, you wouldn't need to do this to get the engine started. If you have a mechanical fuel pump ion the engine, just cranking the engine over should cause the pump to push gas into the carburetor. And if an electric pump, it should come on with the key in on.

But to prime, pour a small amount of gas down the throat of the carb, and crank. As the engine fires and runs, the pump should begin working and pushing fuel into the carb.

I have a 22re toyota pick up with weber carburetor it takes a long time to start in the mornings battery even dies sometimes before starting what do you recomend


Check that your choke is working properly.
Start with a tune-up, new gas filter, air filter if dirty, oil and oil filter, spark plugs, distributor cap and rotor. If your spark plug wires are old, buy a new set, or test yours with an ohmmeter.
If still bad, check if your fuel pump is putting enough gas into the carburetor. Take the gas line off at carb. and check volume flow into a container. Also the carb may need adjustments-maybe the fuel level in carb. bowl is too low-would need to raise float height. Check if the needle valve and seat at the gas inlet to carb is not clogged or stopped from trash or debris.
Look down the throat of carb and watch for gas jetting out when you open the throttle to wide open-you should see gas spurt downward, if not, the carb needs some work to it.
Is your choke adjusted right? Sounds like it may not be-the choke flap should be nearly closed when starting, partially open after running, and fully open after the engine warms up.
Other problems could be weak ignition components-possibly a coil or igniter-what Toyota calls an ignition module.
Post back with what you find. Webers are great carburetors-much better than stock.

87 ford crown vic drove car last nite shut it off went to start it back up to put in driveway started to back in then it died cranked on for awhile no fuel smell at motor is there a inline fuel filter...


old car, very old, and will have lots of ignored problems and skipped maintenance. (as a rule)
do the service, do the full 60k tune up. (did you?)
it's in the manuals, all of them.
and yes, that includes, all filters,

This is a CARB car, right>? (pre 88s generally are)
what engine, lots of engine options.

on carb cars, there are 3 filters (typ)
1: a filter stock in the tank.
2: an inline filter.
3: one on carb is in the , carb fuel fitting. what carb brand?

it has a trick carb too. not conventional. a VV carb.
i log in to alldata dot com, (so can you, and should)
i see
quote
All vehicles with the 5.8L engine are equipped with a Motorcraft 7200 Variable Venturi (VV) carburetor. Fuel is supplied to the carburetor by a mechanical fuel pump mounted on the engine. The fuel pump is driven by an eccentric attached to the front of the camshaft.
The 7200 VV carburetor is unique in that it is able to vary the venturi area according to engine speed and load, which is quite different from standard carburetors which have a fixed venturi area. The venturi area is varied by dual venturi valves that are controlled by engine vacuum and throttle position. The position of the venturi valves change, depending on engine demands, to determine the area for airflow to the two throats of the carburetor.
"
unquote.

the fuel pressure at the pump must be good
the filters clean
if the carb float bowl is dry, the carb will never work..


no starts on all Gas cars. is
bad engine.
bad spark
bad fuel.
(there are simple tests for each)
if spark are soaked, the try super secret unflood mode.
cranking with throttle valve (right foot) wide open
all operators guides say that.
on carb cars, this unloads the choke (if not busted) and you
get mostly air to the engine. un flooding it.
same with newer cars too.

I have a 1987 caprice clasic with a 305 v8 2 barrel that I have to pump the gas pettle to keep it running. could this be the carb or the fuel pump?


this problem is the carburetor which probably has dirt in it plugging up the circuits or a stuck float and when you push on the gas pedal you are supplying fuel through the accelerator circuit.it can be rebuilt or you can buy a rebuilt carburetor,but note you don`t know how long a rebuilt carb has been sitting on the shelf there by it may have dried out gaskets and accelerator pump,and be in worse shape than you own carb.

1987 jeep wrangle will not start or run


Uncouple the fuel line coming from the pump at the carburetor, place a clean can under the line, and have someone operate the starter--you should have fuel shoot from the line in spurts as the engine turns. If it does, then the entry port on the carburetor is plugged. Remove the float assembly and pull out the float needle valve. Hook the fuel line back to the carburetor and try the starter again, there should be fuel pumping into the float bowl. If not, check to see if there is a filter on the fuel inlet path that may be plugged. If no filter, remove the float needle seat to see if something is blocking the fuel passage. If all else fails, use compressed air to blow backwards through the needle seat (remove the fuel line again). Hope some of this helps!

Jeep kicks over but does not start ,,full tank gas


If carbureted, look down into carb & move throttle linkage...see if you have fuel squirting into throat. If not accelerator pump in carb is bad.Or there is no fuel reaching carb. (Ill assume for now that you checked and have spark at plugs, right?)
Does choke close when cold? Did this happen after warm up (before no start at all happened) You have to do some testing ...I can't see it from here!!! Post back if during tests you find anything strange or that need explanation.
