If it was an AUDU/VW I would be sure it is your crankshaft position sensor not working. In this instance there is no problem checking that too. Check if you have a spark at the plugs. If ypou don.t have then your fuel pump wont come on.
The power to the fuel pump occurs for only a short time when key is on,engine off. This is to prime the fuel line. Power resumes during cranking and running. Was the power to the pump checked during these cycles or checked with key on only? Power may be present and fuel pump is not reacting. Hope this helps..
to check the fuel pump on you car you need to put ignition in the on position and open the butterfly of the MAF sensor that is mounted on top of your air filter. Toyota's fuel filter won't come on unless there is air going in the engine. your problem may not be the pump, so you need to check the pump properly.
