Hello I will help you with your question,
What year, model and engine size is your KIA?
2001 optima 2.7
The fuel pump is not turned on until the computer sees 250 RPM while cranking. Can you check that the crank sensor is sending signal to the ECM?
where is crank sensor located on motor
This is the 2.5L V6 or the 2.4L 4 cylinder?
YOu posted 2.7L above but in 2001 the Optima did not come with that engine.
Let me know so I can help
OK, the crank sensor is on the front (Radiator) side of the engine above the starter and below the ignition coils. You have to get to it from the bottom by reaching over the starter to remove the single 10mm bolt and pulling the sensor up out of the block twisting it to get it free. Be sure the O ring comes out with the sensor. Te connector fr the sensor is below the ignition coils.
Please let me know what I can do to help
ok will try
Great, If you have a voltmeter you can check for power on the pink wire of he connector and ground on the black/white stripe wire.
