There has to be a fuel delivery problem. The fuel pump is not working/fuel filter is restricted/injector not working. Start with determining if the fuel pump is operational.
It sounds like possibly a fuel pump issue. The pump may be losing its prime because of a sticking check valve in the pump. Instal a pressure gauge and watch the fuel pressure after shutting the car off. The pressure should not completely drop off it should only drop a few pounds. If it loses more than a few pounds of pressure quickly then it may need a fuel pump. This can also be caused by leaking fuel injectors so further diagnosis is needed to find the source of the leak
sounds like fuel pump is running but can not produce enough pressure. try pressurizing the tank with compressed air(may have an air lock) and if that doesnt work consult your local jag dealer for tips before you replace the fuel pump....
Check Fuel Pump/Pick Up Line & Filter in tank, if the Tank is Dented or Damaged that could cause it not to pickup that last 1/4 Tank.It could MAINLY be your fuel pump though. Because with the car full of gas, the fuel pump does have to work near as hard. Hope this helps, James Booth
It is possible that is plugged. The fuel pump is in the gas tank. when you turn the key on you should hear the fuel pump turn on. I would check fuses first, if they are good while you are cranking the car over have someone else bang hard on bottom of the gas tank with their hand. If the fuel pump is stuck it might start working again. Good luck
Best suggestion would be to put a fuel pressure gauge on and and see what the fuel pressure reads when cycling the key off and on pressure should be 37 to 43 any less then this suspect the fuel pump or an electrical connection to pump. When it acts up and you can not hear the pump running try tapping on the fuel tank.If vehicle starts after that suspect the fuel pump.
The best diagnostic for the fuel pump is a pressure test. Need to know the specs on it (should be around 40-60 PSI), hook it up to a fuel pump tester and there you go.
The symptoms the engine presents when a fuel pump is going bad could include:
- hard to start
- hesitation
- loss of power upon acceleration
- going dead at idle
- others...
But other problems could cause these same symptoms.
replace fuse and relay.also check oil pressure switch.it controls fuel pump also. check fuel pump wires and fuel injector fuse .if all is good pcm could be faulty it controls fuel pump on .command circuit
