ON THE FUEL RAIL YOU WILL SEE A SCHRADER VALVE(LIKE ONE ON A TIRE FOR AIR), IF YOU PRESS ON THE NEEDLE IN THE CENTER OF THE VALVE, FUEL SHOULD SPRAY UP IN THE AIR AT LEAST TWO FEET OR MORE. MAKE SURE YOU TAKE THE CAP OFF FIRST. WHEN YOU TURN THE KEY TO THE ON POSITION, THE FUEL PUMP SHOULD MAKE A HUMMING SOUND FOR ABOUT THREE SECONDS, AND THEN STOP. IF YOU DON'T HEAR THE PUMP THEN CHECK THE FUSE AND RELAY FOR THE PUMP IN THE FUSE PANEL. WELL THIS SHOULD CLARIFY ANY QUESTIONS YOU MAY HAVE CONCERNING THE FUEL PUMP. HOPE THIS HELPS. THANKS FOR USING FIX-YA. KEEP ME POSTED. THANK YOU IN ADVANCE FOR AN HONEST RATING TOO.

Check the valve stem on the fuel line in the engine compartment if it squirts out then your fuel pump is fine

My 2002 Intrigue will not start and seems it is starving for fuel.


You said you checked the pump. Is the pump getting voltage after the 3 or 4 seconds from the relay ?
You get voltage for the pump in the first 3 seconds then none if the engine does not start and produce oil pressure. That is to prevent a fire in a wreck.
Can you jumper the pump relay and hear the pump run past 3 seconds ?

I have a jeep that cuts out randomly whilst driving. I have replaced the crank angle sensor about 3 months ago. It will run fine for 1-3 weeks and then just chug like its running out of fuel. It doesnt...


try replacing the fuel filter. also do you notice a louder than usual fuel pump whine? maybe fuel pump is going out, now, only if you hear the fuel pump working harder than usual should you be concerned about pump issues. also, check spark plugs, coils, ect. if it's due for a tune up, get it done.

If i stop or let idle i feels like its being starved for fuel.. turn off the engine and start it again it runs fine till i stop again. Just replaced the fuel pump a week ago and has been running fine.


Mine did that to me about 4 months ago. I started by changing the fuel filter it ran great for a month. but by doing that it released all the pressure off of the fuel pump which then went out. If you run your vehicle below 1/4 tank it starves the fuel pump. The pump needs that fuel because; The fuel is the lubrication for the pump. Running your tank down consistently over a period of time will short the pump out faster.
