does it have an electric fuel pump, which may be vacuum locking.

Have you replaced the coil yet? I assume by all 4 cylinders misfiring you mean P0300 Random Misfire? It could be a number of other things - a faulty fuel injector, coil, etc. Read this article for more info on random misfires - http://www.obd-codes.com/p0300

Please contact me at [email protected] I will send you full pictures and literature on this subject.After you rate my solution i no longer give out my time and resources for a later rating on my solution which they did not even go back and give me a number 1 rating sorry. This is why i do this for my ratings.

They are everywhere just clean it all for proper oil flow do both sides also i would do an engine flush if build up is a problem for your situation this could save your engine now.

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. • 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.

if its losing water it could be a head gasket or cracked head.

The timing is not adjustable on this vehicle, the computer has a preset Map and the only reason timing ever changes is if the Knock sensors see detonation and then the computer will ****** the timing to save the engine. I think you have something put together incorrectly. Id check for vacuum leaks/misrouted hoses or another problem. Did you pull the codes from the ECM? Thats a good place to start if there are any codes stored. Good luck

Its usually behind the engine by the firewall or bolted to the frame under the drivers side a couple feet in front of the fuel tank. Ive never seen one anywhere else on a stock vehicle. Hope that helps.

Yes... Disconnect the battery, put the key in and turn it to unlock the wheel, put the gear shift in neutral. Away you go.
