SOURCE: 2004 KIA Optima LX timing belt/water pump

The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck

SOURCE: 2004 kia optima lx, engine will turn over but will not start.

The fuel line is connected to fuel injector Rail by 2 nuts (10mm) (from your right) next to air hose to air filter. Disconnect fuel line and start engine to see whether gas shoots out of the line. If not, fuel pump is broken. Engine turns over but not start , it could be iginition lost (no sparks ). or timing belt got rip broken.

Go to auto Zones (auto part store) borrown ODB II scanner loaner and take it home, hook to ODBII connector that's located at the driver side to your right. Read the codes given by the scanner and go from there.

If a timing belt is broken, open timing belt cover to check on the belt.

If your belt is broken and crushed apiece, you may have to rebuild the whole engine as it's an interference belt.

Engine stopped while driving chk eng light on, engine turns but won't start. Computer shows crank position sensor failure w/3 occurances & several emission sensor codes.


A crank-no start condition can definitely be caused by a faulty crank sensor; if after testing the crank sensor and finding it defective you will need to clear the codes and drive for at least a couple of drive cycles to see if the emission codes are legitimate or were simply induced by the failure of the crank sensor.

My check engine light keeps coming on on my 2004 kia optima lx, 4 cylinder dohc, a little over 92000 miles on it. I had the codes checked and got this result: Code P0320 definition: ignition/distributor...


Check with the place that checked the codes for you. Maybe they can test the IG sensor for you. That might help. Otherwise check all the connections relating to the sensor.

Keyless remote wont work dont know how to program


I have a 2004 Kia Optima EX V6. You have to get a new battery for your key fob(s) and take to dealer to program it. It can only be programmed when they hook it up to the computer. Cost around 40 bucks from Kia. Call around some use to charge only 10 bucks. Good luck.

This could be multiple issues.
1.) timing belt
2.) Crank sensor
3.) Fuel pump (although usually they do not just die they get weak)

Check these let me know.
