Ranout fuel and now got bumped and wont do anything

Probably something got loose after hitting the bump.
Check the fuel pump, maybe a fuse got loose or burn, or maybe there is no electricity running to the fuel pump.

a lot of times when running out of gas the pump over heats try knocking on the bottom of the tank while someone cranks it over note even if it starts you still should replace the pump it will not be reliable if there is no pressure to the fuel rail its not working and there would be pressure at the rail if it was

Check the fuel pressure

A quick check around internet sites seems to indicate that only Kias from around 2001 had inertia fuel cut outs. So I figure your problem is probably a flattened or kinked fuel line, from that excursion into the snow.

has the wire to the fuel shut off solinoid come loose or adrift

Modern lead free fuel can start to go off after 3 months. Drain the old stuff from carbs and tank and try a couple of litres of new fuel.

Sounds like a fuel pump issue. Under the hood you have a fuel pump relay.. try tradeing it with one if the others and see what happens. Inspect under the car to see if he dented anything like around the fuel tank. Other than this if you cant find anything then you will need to get it diagnosed professsionaly because we have no way to tell anything sight unseen. You may have a code stored which will help in daignosing. .Just about any part that needs replaceing will cost more than the diag,, thats why you need to have this looked at by someone in person

Is it a Automatic Gearbox if so then you could have done damage to the gearbox as the book said DO not tow ,but lift and tow as you can reverse the pumps in the box ..
But apart from that ,un do the fuel rail and turn on the key if fuel comes out check the spark if ok then is got to be the injectors are not working correctly.

sounds like the dreaded renault immobiliser ,in which case its dealer only as software encrypted.whats happening is the immobiliser is stopping it from starting when key is in start position cranking but it will go with a bump as starter motor key position not activated .try a wire from battery to small connector on starter motor .if it starts which i think it will then you know what to do ...old fashioned way with a push button.but are you getting prepared to lay the golden egg ???just in case

look for a fuel pump shut down switch usuly behind passenger kick panel
