Question about 1998 Toyota 4Runner
I recently got a 93 4 runner that's been parked for 2 years. The only way it would run is if you poured a little fuel in the carb throat. Checked the fuel pump it didn't work (replaced). Test fuel pump by jumping B/Fp terminals. Still unable to start.
Don't worry, there is only about 100 things that can keep the EFI system from working properly. Try this 1st: My '91 4runner wont run properly, or at all, when the Air cleaner / intake assembly is not hooked up / installed, it needs the MAS air flow sensor to measure the incomming air or it will not run. Then, Are you getting positive pressure of fuel to to the engine from the tank yet or is the pump just running? Thread a pressure gauge to the fuel rail on the engine & check pressure with key on / engine off (should be between 35-45 psi) Check / replace the fuel filter & try disconnecting the fuel & return lines lines @ both the tank & Throttle body & blowing out with 25-50 psi air to ensure the line is clear. You may need to vacuume test the fuel pressure regulator on the fuel rail. If you are still having problems, it can be the injector(s), the fuel pump relay or any of the sensors in the EFI system including the VSV sensor, which measures the fuel pressure & relays the info to the ECM (computer). To check & test all of the sensors it will be worth the $20-30 Haynes or Chilton Manual. start with the easy stuff though, then work up to the sensors & electronics
