2 more things I would check one being the float in the carb or the Idle screw and two the PCV valve I had a simallar problem it happen when I push the clutch in. If you need a stock Carb I do have one I'll let it go for $30 plus Shipping costs it need a rebuild but it worked about 2 months ago. Oh and good luck do you have a hayes or chilton book for the truck? <img src="/forums/images/graemlins/kewl.gif" alt="" />

Which screw are you referring to here, speed or mixture? My first impression was the idle cut solenoid, but sounds like that is working correctly. Refer to the FAQ and make sure both screws are set correctly. How well did you clean the jets out when you rebuilt it? Sounds like a jet could be clogged. Can try unscrewing each idle screw all the way out and spray out the holes with carb cleaner. Or you may need to take the top of the carb off and use a straw on the carb cleaner can to individually spray out each jet.

Oh, before you do all that, check for vacum leaks, especially around the base of the carb. Spray carb cleaner around the carb while engine is running and if it surges you have a leak. A leak at the base will make the engine not idle at all.

I had a similar problem and ended up being my fuel pump, and my accelerator pump diaphram had a small pin hole in it that didnt help out either!

I've been having the same no-idle problem on my 84 4Runner.

I checked out the solenoid and it works.
I checked out the harness side and the signal from the emissions ECM to energize the solenoid wasn't there.

Ok next steps taken.
When rebuilding the carb I did not drill the plug to the idle mixture adjusting screw. I have tried all of the other suggestions so I figured this was the only thing I have not pulled out and cleaned. I went ahead and cleaned it. It started with out a problem and idles fine. It runs great, but when I turned it off I could not get it started. Evidently the carb cleaner I sprayed cleaning the idle mix screw hole and down the carb help it start.

All other problems are solved, it idles fine and once started continues to run. But, I still can not get it started unless I pour gas or spray carb cleaner in the carb.

It has to be something that is clogged somewhere but I have no idea where.

Sweet, one step closer! Well it started fine earlier right? Gotta think about what you touched since then. Make sure your screws are set correctly, make sure the choke is functioning correctly. Will it start if you pump the gas?

UPDATE:
It started with out pouring gas in the carb last night and then again this am and I drove it to work. I am not sure what fixed the problem, as last night it would not start unless I sprayed some carb cleaner or gas in the carb. But I went to a friends house last night and we were talking about the problem and he suggested making sure the vacuum line going to the distributor advance was not clogged. So I got home and did not try to start the truck, i just pulled the vacuum lines off of the distributer vacuum advance and blew into the lines going to ward the carb. This made no sense to me as i was blowing air in the direction it would be pulling the vacuum. Any way I put the lines back on, got in and the truck started up fine. I think it may have been from sparying carb cleaner into the carb to get it started may have cleaned out what ever was causing the problem.

I did notice one thing on the way to work. The engine seemed to surge and drop idle when I stopped. I adjusted the idle down a little when I got to work. I will see if this resolves the surge problem.

I would like to thank everyone that has made suggestions, as they have all be very helpful. It is great to have a resourse like this.
