I have changed fuel pump and filter,on my 1988 toyota truck and it will start but won't run.It has 22r motor

Check your set screw, and make sure it's not too low. Adjust the screw to the point that where it idles at the proper speed. Also, maybe check your throttle cable for too much slack.

Good explanation of symptoms.Thank you.




No assumptions.
Diagnose problem.
Pinch off the fuel return line.
Check fuel pressure--I don't wanna!PITA!
The fuel pump won't run if the fuel filter is plugged up.
Toyota's have a gas tank drain plug!!!!!!!!!
My '84 takes a 3/8 " ratchet. Cool.

There may be a fuel pump relay that is toast,but I suspect the filter,off hand.
A plugged filter will overwork the pump and cause the engine to run rich.

Check the steel fuel line under the intake manifold
had one that was almost completely clogged shut with ****
took a month of hunting but found this to be the problem

The number one problem with these cars is with clogged fuel filters. They must be changed regularly. When you say it won't start, do you mean it cranks but won't fire? That could be a fuel pressure problem due to a clogged filter.

Dripping fuel could indicate a badly adjusted float,bad needle and seat,or possibly to much fuel pressure off the pump,if your using a mechanical fuel pump make sure the return line to the gas tank isn't plugged,if your usining an electric fuel pump make sure you have a working pressure regulator,my personal opinion on remanufactred stock carbs isn't very high,if you can return the carb I would highly reccomend replacing it with a Weber 38 DGES,you can get a Toyota conversion kit for around the same cost as a remaned stock carb.

Hello,
Sounds like you have a bad carb. While the choke is on and active it sucks enough gas into the engine to keep it running. To test this problem run the vehicle until it is up to operating temp. Give it the gas and see if it does the miss and sputter thing. Then using a can of either of other flamable carb cleaner spray some into the air cleaner nozzle while the engine is acting up. If it smooths out for a few seconds the the carb is not gertting enough fuel at high rpm. rebuild the carburator paying attention to the fuel ports in case one or more are plugged up. Also look at the fuel level float and see it it is set at the proper height. It has been a while since working on a 22r carb, but I am not sure if thereis a fuel bowl window that you can look at to see the fuel level with a flashlight. it should be at or slightly above the dot on the glass window in the carb. If low it is a fuel problem. Also while working on it check the pressure on the fuel line at the carb. Your service manual should have a recommended pressure for the carb. Regards, rcampsr

You might check the PCV valve and grommet,I'm assuming it's EFI,if the valve isn't sealed tight it will cause the motor die at lower RPM's

Hello;
It sounds as if you have a couple of possible problems. First could be the fuel pump. If yoou disconnect the fuel line, put the line in a jar and crank the engine over, you should get a pint in 15 seconds or so. Also check the pressure, should have around 5 psi. Secondly, you may have a vacuum hose cracked, broken, or leaking. Check your hoses and also the carbureator for leaks.
Hope this helps;
Thanks;

If you have a tps and air flow meter you have a 22re fuel injection.
Check for codes by jumping TE1 and E1 or jumping diagnosis connector.



The 22re will run with out the tps(throttle position sensor) plugged in. But it will not run with the air flow meter unplugged. The air flow meter controls the fuel pumps voltage.

This page tell you how to test those sensors. Then we can go from there.

The fuel pressure regulator may be shot also, but we will see.

I hope this was helpful.
