02 kia sportage suddenly died on highway at full speed. No sputtering, no surging nothing. Just dead. Turns over and tries to fire but won't. I have replaced, fuel pump, fuel filter, relays (main and fuel pump more than once), I have switched out ecm with a known good one and am stumped. Checked grounds, timing and spark ...all is good. I have gone into the fuse box under the hood and started testing the circuitry. In the fuel pump relay I have power going to the black/red wire(hot all the time), red/blue wire (o2 sensors?) and the dbl green wires(when ignition is on;they go to crank and camshaft sensors.)I also have a single red wire that goes to the ECM. It gives a slow, faint glow and also ''clicks'' when the test light is on it. The only wire that has no power out of it is a single blue one that goes from the relay to the fuel pump fuse, which in turn heads to the fuel pump via a green/yellow wire. Why am I not getting any power to the fuel pump fuse via the blue wire coming from the relay?????

hang on a minute their is a fuel cut off switch somewhere for emergency use in case of an accident ,it shuts the fuel off ,Now where it is on this vehicle i dont know buit try looking under the bonnet for a small electrical block/switch looking thingy with a red rubber cover about an inch square and push it down .If it clicks down then you will find it should be alright again hang on a minute their is a fuel cut off switch somewhere for emergency use in case of an accident ,it shuts the fuel off ,Now where it is on this vehicle i dont know buit try looking under the bonnet for a small electrical block/switch looking thingy with a red rubber cover about an inch square and push it down .If it clicks down then you will find it should be alright again

it will have a fuel cut off switch somewhere ,regulations , but i just do not know where ,and still waiting for my all data book to arrive it will have a fuel cut off switch somewhere ,regulations , but i just do not know where ,and still waiting for my all data book to arrive

must be some way of running pump ?? by pass the relay?? must be some way of running pump ?? by pass the relay??

all vehicles that require a certificate of homogolonation in europe have to have this safety cut out ,?? but its possible it doesnt have one in other countries .if its the earth not connecting then use a relay running off the ignition switch with the other connections makiing the earth so that it turns off when key is turned off.Personally i would take the sender unit out of the tank and have a look in case the gauze filter in the bottom is blocked or a plastic glove is swimming around in the tank ,wouldnt be the first i have found in the tank ,you know the ones they supply in the gas stations ? all vehicles that require a certificate of homogolonation in europe have to have this safety cut out ,?? but its possible it doesnt have one in other countries .if its the earth not connecting then use a relay running off the ignition switch with the other connections makiing the earth so that it turns off when key is turned off.Personally i would take the sender unit out of the tank and have a look in case the gauze filter in the bottom is blocked or a plastic glove is swimming around in the tank ,wouldnt be the first i have found in the tank ,you know the ones they supply in the gas stations ?
