Its possible the gears are not on the right marks.
Have you checked cam timing since replacing the second belt ?

Firstly I would check/clean that big multi plug on the right handside on top of the engine.This plug gives problems and probably disturbed during timing belt change,then sell it!

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.

SOURCE: Car would not start, after siiting for an hour it did start .

mcdevito75 here, BEST BET, let the shop do this work, too many un forseen problems could come up. The stalling and unable to start for a while could also be a bad ignition module, no test for this part, but I would have it changed, for if it is a bad ignition module, all this other work will not fix the stalling and later start of your car.

SOURCE: car wont crank: code that

Odds are, if the code says a bad crankshaft sensor, then that's exactly what the problem is.

As to your comment about the timing belt.

Are you sure you really mean the timing belt?

It seems unlikely to me that you would have removed the timing belt cover, in order to make this determination.

I'm more inclined to believe you are talking about the accessory drive belt (AKA serpentine belt) that drives things like the alternator, AC compressor, power steering pump, etc.

This is on the outside of the engine and is plainly visible. A small amount of play isn't unusual.

Replaceing timming belts A, and B,

If I understand you correctly it seems like belt "b" came off. If in deed it came off it is possible that it did som damage to the crank sensor and now since the computer doest have an rpm reference the vehicle won't start. You may have to revisit the work done and make sure everything is in order. Keep in mind this is an interference engine. Meaning that misalignment of the cam and crank or a belt coming off or breaking while everything is in motion will cause internal damage to the engine. Good luck.

2004 Jeep Grand Cherokee temp gauge high when heat is on

If your "check engine" light is turn on, I suggest scanned the PCM to know exactly what fault code is stored there. Additionally, could be some problem with the "temp sending unit".

Need how to set timing belt on kia optima

I had 2006 kia optima 2.4 liter LX, I drove 150000 miles plus, it was over 100,000 miles I changed timing belt, and AC belt, alternator belt is still ok, but it was my fault, I did not change crank shaft balance belt, it next to timing belt, this very important, timing belt and crank shaft balance belt must change same time, you set all mark the same positions, you can see all clear marked
if you had OBD2 scanner is helpful to read all faulty codes if you do it your self repair
if you have any problems about KIA optima, please post on any websites, to share some ideas to other KIA optima owners, like me, I change oil every 2500 miles to make my optima runs smoother
automatic transmission fluid change every year if you put high mileage on your car, optima had hard time to find it own part some time, radiator hoses are still good condition and had hard time to find in any auto part stores in my home town, good luck and thanks for sharing.

the pcm will try to "guess" if it is not recieving the input it is needing from the sensors and that could be the reason that your vehicle ran "fine" after restart. there is still a reason that the mil lamp came on. needs to be scanned to retrieve the code for proper diagnosis

Changed timming belt while replacing the water pump

since it ran fine at first, I would think you got the cams and crank correctly timed. the two connections in the diag box to connect are "T" and "E1". You may want to check out the distributor to see if the air gaps from the star wheel to the pick up coil projections are less or more than the correct--.008-.016". If so, the bearing is bad (the star wheel will wobble) and you should replace the distributor. Also, the distributor has three coils in it that should be checked for proper resistance--140-180 ohms. The car will run with one of the three coils dead but not as smoothly.
