2004 kia rio... was driving on highway and then sudden loss of power... now starts but as soon as you touch gas pedal engine dies... recently changed motor and clutch and crank sensor

Any codes?Do you have gas?Is Battery is OK?mean crank power.

TPS ( throttle position sensor) could be out of adjustment or bad. If it was a timing issue it would run poorly or backfire

The crankshaft and camshaft sensors will cause this problem.

Well, to begin with, the LAST thing I would replace if a vehicle died going down the highway is the starter. What caused the engine to die? It certainly was not the starter!
If the starter will not crank the engine over, you probably have a dead battery. If your battery went dead while driving the vehicle down the road, you most likely have a bad alternator. However, it is really hard to say without actually being able to see the car.

Could be a transmission problem, or other fault. Best recommendation I can give you is get the Haynes repair manual for your vehicle and if an Auto Zone is close get them to read the fault code for you. That will tell you what the problem is and give you an idea if it's something you can fix.

had similar problem, 2003 rio 1.6l idle fine and die when trying to accelerate or lurch and die ran fine in reverse change timing belt,wires plugs, had codes for multi cyl misfire and low injector voltage, still same lurch and die. try wiggle test on sensor plugs and main engine harness between battery and engine . i did this and found car smoothed out,tried wiggle again and car died,took harness apart where i wiggled it and found broken wire to crank sensor.good now

maybe your fuel pump stop working or a blown fuse for the fuel pump or ignition coil. First checked for blown fuses

check to make sure the vehicle is firing, by removing one of the sparks plugs wire and ground it our on the engine by placing a screw drive inside the end, if done correctly u should see spark

i need engine for kia rio 205 to by

You probobly threw a timing belt wich in turn caused damage to the valves and piston heads. I just replaced my engine because of it.
