Question about 1998 Toyota Tacoma

1 Answer

Toyota Tacoma fuel problem

1998 Tacoma 2.4 engine with 2wd, 5 spd. Stopped for fuel. Moved to air station for low tire, got done, wouldn't start. Replaced fuel pump. No start. Traced wiring to Circuit Opening Relay, crossed up power to pump wires, engine started. replaced COR. Engine starts, 2 seconds and dies. Tried T/S flasher between power and pump wires in COR. Started and ran fine at idle. Started to drive and felt every flash of T/S flasher in fuel system. How do I get it to run (properly) with COR connected? It's used for mail delivery and has 280,000 trouble-free miles on it. ECM or Ballast Resistor you mentioned in another post? I'm getting gray hairs. Any info appreciated.

Check the following:
- Listen to the fuel pump noise under the fuel tank.
- Starter signal.
- EFI relay, under the hood fuse and relay box.
- Fuel pump operation and pressure.
- Regulating valve.
- Circuit Opening Relay (COR) under the dash.
- Check for open in harness and connector between circuit opening relay and fuel pump, and fuel pump and body ground

SOURCE: no power to fuel pump. I have power up to the circuit opening relay.

I am not positive how the electronics are routed on a later model truck but I had this same problem on my 89' with a 22re. It turned out that the oil pressure sending unit was in the fuel pump circuit so as to not allow the engine to start with no oil pressure. I changed my sending unit and the truck fired right off. Hope this helps.

SOURCE: 1992 4Runner circuit opener relay causing rich Idle

It may be that the O2 sensor is faulty or contaminated. Another possibility is that after running rich for some time, the catalytic converter is slagged and no longer working properly. Have you been able to get any diagnostic codes from the car's computer? Is the check engine light on?

Temp sensor on 1998 toyota tacoma 3400


The engine coolant temperature sensor is usually located on the thermostat housing. This sensor controls the readings of the coolant temperature gauge in your vehicle when the ignition switch is ON .Here's a link to the sensor. REMOVAL & INSTALLATION

  1. Drain the coolant from the vehicle.
  2. Disconnect the engine wiring protector from the brackets.
  3. Disconnect the sensor wire.
  4. Using a 19mm deep socket, remove the sensor and gasket.
To install:
  1. Apply a thin coat of Loctite or equivalent to the switch. By hand, carefully thread the switch into the engine. If resistance is felt at all, remove the switch and inspect the threads for any damage. Continue to install the switch. Once installed, tighten to 14 ft. lbs. (20 Nm).
  2. Connect the sensor wiring.
  3. Install the engine wire protector to the brackets.
  4. Refill the coolant. Start the engine and check for leaks.

2006 Toyota Tacoma Prerunner, 2WD, 4.0L V6, 5-speed Automatic has a severe vibration from the speed of 20 mph to 50 mph, then the vibration will slightly deminish.


Is it the engine vibrating or the car? If its the car itself it sounds like u need to have the tires checked & balanced.

How can I change fuel injectors on a Toyota Tacoma 98 4 cylinder


The Toyota Tacoma has a fuel injector that mixes fuel with air. This technology almost completely replaced carburetors in the late 1980s and its programmable firmware allows the same hardware to be used with different fuels. A fuel injector is only a nozzle and a valve; it still requires a pump to inject the fuel into the engine.
    • 1 Determine which fuel injector your Toyota Tacoma will need. This depends not only on the make and model, but also the engine size. Models made before 2005 may have a 2.4L, 2.7L or 3.4L engine. The current version may have a 2.7L or 4.0L engine.
    • 2 Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Remove the engine under cover subassembly and drain the engine coolant. Detach the intake air connector and disconnect the throttle body motor assembly with a socket wrench.
    • 3 Disconnect the fuel lines and remove the fuel pressure pulsation damper assembly with a socket wrench. Unplug the electrical connectors for the fuel and vacuum switching valve. Remove the engine wiring harness clamp and the air conditioning compressor clutch connector with a socket wrench.
    • 4 Remove the two fuel rail mounting bolts with a socket wrench and lift out the fuel rail with the injectors still attached. Pull out the fuel injectors and discard the old gaskets.
    • 5 Use new gaskets and install the new fuel injectors by reversing the removal procedure.
    • 6 Fill the coolant reservoir with coolant of the proper grade and type. Start the engine and check for fuel leaks.

Tire pressure guage indicator in 2006 Toyota Tacoma


Yes, this is indictating at least 1 low tire of the 5, maybe more...Check ALL 5 tire pressures and set them to 29lbs, as per the specs and then turn your key to"ON"...then push and hold the button under the steering collumn until the light on the dash flashes 3 times, indicating that you have re-set the computer to recognize the pressure that you now have set....

Good luck.
