My YJ Jeep 189 wont start, I accidntly shorted the wrie on electric choke by touching to carb with screw driver , the Jeep shutdown and now will not start, any thoughts? HELP

ok, so you know where it is nor not?
its in the heater box.
and the box is in the dash
so, the box needs to be removed.
then box split (screws)
then replaced,
the FSM covers this,
ive posted this over 100 times here.
again.
YJ, the real deal. real jeep book;
yj 93 is here for free, they are same.

try a new coil.some times a new coil will fail

The idle mixture screws do not control the idle. Is there no idle screw? If you have an anti-dieseling solenoid on the idle screw, make sure it is coming on with the ignition switch and use it to adjust the idle. Set the idle and then adjust the misture screws to maximize intake vacuum at idle. Readjust the idle after adjusting the idle mixture. The port at the back of the carb is not used in all systems. If you have a distributor with vacuum advance, make sure the correct carb post is connected to the distribtor. Adjust the choke and fast idle to engage when the engine is cold.

On a carbureted car you need to pump the gas pedal a few times before starting it when it's cold. Before attempting to start, pump it four times. If it starts, next time try three, then two. Once you find what the engine likes, stay with that. if it still won't start, with the engine off, look into the carb and watch for a squirt of fuel when you move the throttle linkage, if there is none the accelerator pump isn't working.

Your carburetor has an electrically controled choke thermostat. In addition to this you have what is known as a choke pull-off diaphram. this pull off over a peroiod of time wears through the rubber diaphram and it fails to open the choke the necessary amount to stop from choking the engine out completely. Now, during this failure your sparkplugs have become irreperably blackened with fuel soot and they cannot be cleaned. this is why once your engine warms up it will not run because fouled plugs will only fail when they are warm. You need to have your choke thermostat, your choke pull-off valve and your spark plugs checked and or changed.

mine problem was identical, the fuel filter has a return to tank on it and when it starts to get plugged it returns all the fuel to tank and not start, i crimped the return with vise grips and it started right up so i knew to replace the fule filter

If you have a carb you do not have a map or IAC valve. They are on fuel injected throttle body setups. You really should go to an auto parts store and get a book if your really interested.

It would be great if you could find the Ignition Control Module!!! From my experience on my Jeep...90 YJ 4.2 liter carb. it does not have one...Computer controlled only...

sounds like you need to rebuild your carb. I just had mine done for my jeep the hardest part was finding someone to do it. ps mine only cost 50 bucks so dont get ripped off. good luck and hope this helps.

OK I have a yj and you start from the windshield put the snaps/or what ever yours is on the top of the doors then down the side or the doors then under the back side window then around the curve and this is the hardest part then your tailgate also make sure your bars on the inside are loseuntil the top is on then thighting those bars and you should have a nice tight top but belive me it is hard and you might need a flathead screw driver for the corners. Good luck and a jeep wave to you!
