I have a 2000 toyota rav4 it has no power going to the camshaft sensor or fuel pump I replaced efi relay and fuel pump relay all fuses are good I also tried a new ecm computer no differance not sure what to do next
Pulse signals from what? speed sensor abs wheel sensor fuel pump pressure sensor crankshaft sensor camshaft sensor knock sensor
even though it sounds like it is pumping it may not be, try a new pump and new fuel filter
IT CAN BE A FUSE. OR IT CAN BE THAT THE PUMP IS NOT PUMPING FUEL
If you're getting power to the pump this proves the fuel pump fuse and fuel pump relay are good. That leaves only two possibilities. Either the pump is running but it's not pumping fuel. Or possibly the fuel filter is clogged.
On the 4.0L, a camshaft posion sensor that is part of a oil pump drive housing.On the 4.0L, a camshaft posion sensor that is part of a oil pump drive housing.
When it's not pumping fuel.
Th cam sensor is under the power steering pump; To service the sensor the pump has to be removed.
The Camshaft Position Sensor is located behind the Power Steering Pump.
you can check your fuel pressure! check the timing, maybe even your crankshaft and or camshaft sensor. maybe weak fuel pump
Loss of fuel (fuel pump) loss of ignition ( crankshaft or camshaft sensor or wiring)
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
