SOURCE: 2004 Kia Optima no start after timing belt, crank, cam sensor replacement

my thoughts on this are that you have the car timed on the wrong stroke. a four stroke engine has an intake and an exhaust stroke that if it is timed on the exhaust the crank and cam sensors will not know when to fire the ignition or the injectors they will essentially be firing when the car is trying to excavate the mixture of fuel into the exhaust manifold. double check the timing of the car and go from there. If that is already done then I am assuming that the car has a crank sensor that needs to be gapped correctly into the ring as does the cam sensor. This is a common problem among many makes with these sensors that take the place of traditional timing and distributor.

Try the ignition switch,

For the Crank sensor there is a small metal disc that mounts behind the sensor if that is cracked or dammaged or installed backwards you will get same results as if it wasn't Make sure the timing marks line up on your timing belt. www.kiatechinfo.com

SOURCE: 2002 Kia Sportage will not start.

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: 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.

2002 trail blazer will not start,fuel pressure


you might want to check to see if you got a timming chain or belt in that car.
but check that area first .
could be a broken timming belt.
you need to remove the dust cover in that area .
check for no belt present on the timming gears.
good luck,Gary

My sidekick will just die or barely run it died


last year, OBD1 car (dumbb ECU)
no scan tools for it
if you run on the road with that hack , and wreck
expect a nice fire. fuel fire.
if you used a voltmeter and say 12vdc there, all hotwiring stuff
need not be done. (
it stalled (misfire)
and then would not what? start but cranks ok?
4wd?
3sp ,4sp auto or 5speed stick
16v engine or 8v, both are G16s but EFI radially different.
16v is MPI with 4 injectors, 8v is 1 injector TBI
try a new
cap,.rotor spark wires and spark plugs yet?
cant burn fuel with bad spark
i guess the cam bent did not slip as it run ok later, but is 60,000 mile belt. and will slip ignored.

next time it stalls
check headlamps they work, and all electric
then see if CEL glows key on, i must or ECU lost power
it has 3 fuse that can rust, IG coil, FI, and DOME.
the CEL must glow, is first checks.

Car dies when driving,check engine light comes on.


There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.
