I write better in English. Vehicle: 1992 Toyota pick-up, ( same as Tacoma, but before they called it "Tacoma" ), 4WD, cab extra, 4cyl 2.2efi engine. I first experienced the problem of truck running very rough, will stop running as if missing very badly in 2005. At that time I changed the fuel filter and pump. Seemed to help; truck ran very good with only little gas in tank. Since last winter when truck has less than 1/2 tank of gas it starts to run very badly ( like missing ignition ) and will stop. To turn off the engine and restart the problem disappears for a few miles, then returns. To fill the tank there is no problem; truck runs very smooth and strong ( as much as 4cyl will run ). So I'm able to drive by refilling @ 1/2. I would change parts except that to restart the truck when it runs badly, the truck runs great for 8-12 kilometers. A previous responce from "ask expert" was to check ventilation of tank ( air make up ). I have driven with the gas cap loose, also removed the catilytic convertor. The same problem occurs; at 1/2 or less, with the engine very warmed up , starts to die and will not acelerate ( will not make power, wanta to stop ). Thank you for your attention. Larry Bradburn

Hi dear friend.

Your problem seem to be the fuel pump colector inside the tank, its common to see this kind of issues, you may need a new fuel tank or rebuild your tank, this colector is like a box in the tank so when you have low gas, the colector is always refill, by the way i suggest first remove the microfilter in the pump, before check the tank collector, have a good day.


best regards.
