My 1992 Toyota Truck 4x4 22 RE 4 cylinder 5 speed, about 90k miles has been stalling for approximately 3 months.
In the beginning, the truck would start and would stall when the AC was turned on. I replaced the Mass Air Flow meter as it would stay running if we moved the flapper door. It ran for about a week and then began having problems again. Regardless of anything being on, the truck will start and die after about 5 seconds. It will only stay started now if you hold the ignition in the start position, or if you put a good amount of starter fluid in the intake.
I have checked for vacuum seals/leaks but there are none. I've replaced the fuel pump, filter, ignition coil and ignitor. I've checked the throttle position sensor and maf-both tested fine. I've cleaned the throttle body with a tooth brush. I've replaced the distributor (though we aren't sure about the timing). I've checked the computer and it does not show any coding. We have ordered another computer but it has not been installed yet.
My son is a mechanic and we are both stumped as to what else we could do to try to fix it (except paying 300 for a diagnostic at Toyota). Could it be a sensor? Any ideas?
