    on the same page as you
    picture of car and engine in first answer

    so timing marks are correct and there is good compression on cyl one
    engine light should be on

    have you got continuity tester an led test lamp / amp /volt meter as part of you r tools
    i am thinking
    if all the wires are sound and test ok
    replacement cas could be faulty
    replacement ecu has that code stuck in its memory

    massive coil on that car

    if you did coil cas and ecu at the same time
    bit difficult to know what was faulty

    wonder if the pin into the ecu is bent/corroded or cas plug or coil connection
    did your ecu replacement have the same casing numbers

    I will do a few tests and let you know asap
    Thank you

    while testing stuff
    unplug a few other sensors
    see if the diagnostic tool picks up the ones you unplugged
    and then if all those fault codes clear after plugging them all back in

I have these codes reading now po700 po335 and po727 any idea what to check first on 03 kia sorento. my car lost power then shut off, then wouldn't start

p0335 is a crank shaft sensor error. This sensor is what tells the ECM when to send spark to plugs. That is why it wont start.

Why the motor wont runn after alternator fixed

The computer is not getting a signal from the crank sensor.
A low battery could cause this, but normally it is the sensor or a wiring problem.

Car wont start

being 94' im sure it has high miles, cam and crank sensor common to fail over time do to wear and heat exposure. check the basic, make sure you getting fuel and sparks. fuel pump only work as long the engine is turning over due to the crank sensor sense the flywheel turning. crank sensor may be faulty. no sparks, check coil make sure is good and putting out 12v, auto zone can test it for free. good coil, than check cam sensor, cam sensor senses the cam turning and tell the ecu to tell the coil to disperse the sparks to the plugs. cam and crank sensors, there no way of testing it but replacing the unit unless you have the special equipment to test it; both is fairly cheap to replace, check ebay.

My 1997 chevy cavalier wont start.its getting spark and fuel.but wont fire it has a 2.2 ecotec.

Sounds like cam belt has snapped. If it broke while starting, could be cheap belt. Worst case: cylinder head off for overhaul...bent valves / pistons replaced.

The crank and or the cam sensor has failed. If you have no way of pulling codes or checking for signals from the sensors, start with the crank sensor, its more common.
