Changed fuel pump and fuel filter, now x5 2002 won't start

the only way to tell is to have the fuel pressure tested with a gauge when its running okay then have it tested when its acting up. this will show any type of pressure and volume problem that could indicate a pump problem. when and how long has it been since you changed the fuel filter. pumps will usually act up when they get hot or when you have just filled up on gas. they will also act up when you have driven a bit and shut the engine off to go lets say into a store and come out and try to start it. this is why a fuel pressure test is important.

First- have you ever changed the fuel filter? 2ed- take it to your mechanic and have them do a fuel rail test. Sounds like a week fuel pump. GOOD LUCK!!

fuel pick-up in tank is blocked it has a sock over the end as a gross filter to keep out any big junk from getting sucked into the pump and causing damage to it. the sock can get so plugged up that no fuel will flow, causing the pump to run for a short time then with no fuel flow to cool it it trips the safety and shuts off

I think you are on the right track. It sounds like you have a fuel flow problem and those are the two items that immediately come to mind. I would start with the filter and then move on to the fuel pump if there is no change.

Check 4 bad earth

have you tried the ignition module on the distributor ? thats how they act when they go bad then they go altogether and wont start at all

there is a cut off switch in the trunk that trips if your car is struck. Its call a fuel cut of switch. look in you owners manual, it is in the trunk black with a red button on top, push to reset.... it should click if its been tripped .. Hope this helps

Possible inertia switch if veh is equipped, let me get this right though, the light came on when the veh stalled??? didnt they all come on???? warning lights i mean???? try pouring a lil gas into the throttle body and then turning over with the starter, if this works and makes it run for a second then your veh is not getting fuel. if its not getting fuel, then there is no fuel pressure. If there is no fuel pressure there is either a leak that you would almost have to see, or the fuel pump is not running. One way to tell if the pump is not running is to have someone turn the key to the run position while you kneel at one of the rear tires of the veh. you should hear the pump come on for 1- 3 seconds, kind of a whining sound, but slight. If its coming on, but the veh still wont start without adding fuel ,that still doesnt mean that the pump is good, but will eliminate the inertia switch. reply and we go from there...

my deawoo would not start when I went to go home after work.

sounds like you need to prime the pump.
