2000 kia sephia replaced engine now no spark

need to replace blower motor....behind glove compartment....I also have a kia sephia 2000 had same problem....

hope this helps there are four engine types

take you car to an auto parts store that checks your check engine code for FREE most of the chains do.take a pen and paper thats in case they cant give you a print out .you need the codes and what they are also get the trouble shooting tips for those codes .if you still need more help repost with the codes and what they are..... example p0100 mass air flow circuit malfuntion.todays cars all start with those codes it help you narrow down the problem

check your timing belt put no 1 cylnder at top dead center timing mark at 0 remove your distrebuter cap and see if the rotor is pointing at number 1 spark plug
if not replace that belt (replacement is at 60k I believe) sounds like the fix good luck CJ ps no. one on compression stroke

Change your plugs, sounds like they are worn and nit firing as strong when on a pull. Or check for jumping sparks from the engine area at night. It could be a wire jumping out sparks hitting any metal around the wire.

Try running some fuel treatment in your fuel tank, if that doesnt help, try checking your spark plugs, It might be time to change them.
Good luck

Change the fuel filter and pressure regulator, restart the computer.

you have air leak around the throttle body gasket .

coil packs or wires

did you gap your plugs to proper gap
