2 solutions: first, ignition control module is getting hot and shutting car down. 2nd; you didn't mention your dash(service soon) lights were on.<p>
You said the fuel filter was pretty clogged up. It's sounds like a bad case of EGS(ethanol gas syndrome). The ethanol;being a corn deritive;acts like corn liquor(which is what is is), and turns the fuel to goop, and adds large amounts of water through out all the systems.<p>
It clogs up the fuel lines,the injectors, and ruins fuel pumps. It also puts heavy carbon on egr valves, int. and exh. valves, and can ruin oxy sensors, and catalytic converters.<p>
Let's try the cheapest way first:Buy a can of SEAFOAM and Berkline 2+2 at your parts store. Take out the oxy sensor(s) and clean the ends using the 2+2 and re-install.
Then change out the fuel filter again. Pour the SF into a tank of PREMIUM(only) gas. Change the pcv valve. Then start vehicle and let idle for 3-5 min(even if you have to rev it up to do it to get the SF flowing through the system), and then drive it 10 hard miles.<p>
Replace that fuel filter, and then let it idle some more. Your car sounds like it is really messed up bad. Unless you take it to a garage that has a fuel system cleaner machine, this is the best way to do it.<p>
After this, add SF every 3-5000 miles to your tank. It will prevent this from happening again. Also; to be on the safe side. Have a PSI check on your fuel pump. This goop could have burnt it up. I hope this helps.

unplug the cam sensor behind the water pump pulley; see if it starts; if it does, shut off engine; replace both cam and crank sensors because crank sensors go out in these engines

SOURCE: My 2004 Kia optima recently died while being

Then you have a intermittent spark . Now do you have a spark tester to test spark. Its okay if you dont we have one . Oh by the way you did the fuel pump yourself. if you can do a fuel pump then you can do this to solve the no start problem. No spark tester? okay we will use that tachometer (RPM gauge). crank the engine does the tach meter reads zero at all times while cranking, if it does youll need a crank sensor. Here the story Rough running conditions and or stalling was caused by a faulty crank sensor, try shaking the connector or wiggle the crank connector then see if it starts. Youll need to inspect the connection for proper male to female connection these have been the most suspectable failure of KIA. If you decide to replace this sensor make sure connections are good, more than likely this was the problem and not the fuel pump

Start with the simple and replace the fuel filter. The fuel filter should be replaced every 15,000 miles or once a year to ensure the fuel system is running 100%. Auto Zone will have the fuel filter and can give you the step by step instructions to getting the job done with common tools. If it's the fuel pump failure, you have not gotten the car restarted. Good luck and keep me posted, be glad to know you got your car running 100% again soon and please rate.
