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.

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.

Best bet is a Haynes manual from your local auto parts store. These have in depth information on each vehicle and great photos of an actual repair to help you. These are $21.99 at your local autozone. Hope this helps :)

Hey Tim take a look at this, will this help ?
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
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).
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
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
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

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.
