Carb.? Choke not working or not adjusted properly/ Fuel Injected? Perhaps loosing prime (bad injectors)? Weak fuel pump?
What i think that the fuel pump in your car could not be working properly. In other words, its not sending enough fuel to the cylinders to start the car. If that is what is wrong.
Delayed start generally means week pump or fuel pressure lost in the line, If working properly there is no delay in the start, pressure should remain for an instant start. If replaced with a new pump and now delayed start, take it back to the technician to check the problem.
the vent in your fuel tank is not working properly
A fuel pressure test can determine if the pump is working properly or not.
If the fuel pump is inoperative, the car will not start.
Many things can happen: Engine runs rough Poor fuel mileage Engine does not start Back flash (ignition of fuel inside intake) Back fire (ignition of fuel inside exhaust)
Also you might want to check your oil to make sure it is up to the fill line. That will also stop the fuel pump from working. A bad sensor will cause a no start problem because it sends a signal to the fuel pump if it is working properly and you have correct oil pressure. If it doesn't send the signal, no fuel will be pumped to the engine.
Check for antitheft system preventing fuel pump operation (look for bad lock cylinder) or insufficient fuel pulse as from improper ECT voltage.
Either the fuel pump isn't working properly or the fuel filter is plugged.
There are a number of reasons why your Toyota Previa will not start. You should ensure that the battery is working properly, that the engine is able to pump fuel and if you cannot resolve the problem, you should call a mechanic.
