when i start the vehicle its idles ok, the problem only comes when i try to drive it it has no power to drive it start to sputter and make boom sound, and when i stop for a shortwhile it builds up its idle some times when i try to step on my accelarator it cuts and i have to start it again, if you hear it idling you would think all is well until you try to drive it.
the timing has already been done, i have changed the belt and the head gasket because it had blown, it now a month after this change and i have been driving it well, i was also told to replace the pump which i did now it only idles and does not drive the fuel being brought to the engine is just enough to make give a good idle
yes i have done all pressure tests and there is 12volts going to the tank, its only by the injectors that you notice that the fuel going into the cylinders is not enough they do not have the pressure that the fuel has when it leaves the tank
