My 1989 Toyota 4runner (22re 240kmiles) is acting up. It something takes me really long to start it, you can hear the starter doing its job and the battery suppling enough power to it (checked the terminals). It started to get a little cooler over here in california (i know some of you live in sub zero places i am just mentioning it.). Also it did this once, i was on a light and i was completely stop with neutral on and the thing turned off. Took me about 3 tries and then it started running again. Also, a couple of miles later (same day), i stopped for 20 seconds and then gave it gas again, and as i was taking the clutch out and giving it gas it kinda wanted to stall so i gave it a little gas and it just revd up to 2k rpm like nothing. It doesn't feel like it is lacking gas on highway. So any recommendation on the subject would be great! Thank you very much for your time!.

Hello fellow Californian! It's been dropping into the low 40's F here so I know what you mean. We've been warming up to the high 70's/80's though too.

Off the bat: when you're trying to start it do NOT press the accelerator pedal at all, at least until after you smell raw fuel in the exhaust. If / when that happens, turn the key off, press and hold the pedal all the way down, then go to start it. If you press the pedal while cranking, the ECU may think you are trying to accelerate rapidly and inject too much fuel, flooding the engine.

First thing I would do is check for trouble codes and post those codes here. The page I'm going to link to shows you how to do it and gives you some trouble codes, but not all of them are correct so I wouldn't rely on it for absolute authority: http://http://troublecodes.net/Toyota/ (you are interested in the top sketch of the three showing where to put the jumper in)

I would have someone crank the engine and listen by the fuel tank to see if the fuel pump is running. If it is grab a multimeter and test the Cold Start Inector Switch (http://personal.utulsa.edu/~nathan-b...ne/39colds.pdf) and Cold Start Injector (http://personal.utulsa.edu/~nathan-b...9coldstar.pdf), and check that when cranking there is voltage at the Cold Start Injector Plug.

If the pump is not running... that's another issue and may have several causes, but most likely the Circuit Opening Relay is not responding to your ignition switch and turning the fuel pump on (http://personal.utulsa.edu/~nathan-b...38circuito.pdf)
Another thing you should probably check is the Coolant Temperature Sensor on the front of the intake manifold: http://personal.utulsa.edu/~nathan-b...40engineco.pdf

You say it wants to die sometimes, or actually does die when idling. How is your coolant level?
