its an electrical item. most probably short circuit. a spoiled engine ECU means engine cant start. simple as that. at least if sensors not in working order, the CHECK ENGINE light will be on for reminder.
zan : u're definately right, if the ECU is totally KO then of course it will tell us. But I would love to know how to tell if it's NOT totally faulty but part of it or going to KO?
SkYwAlKeR : at this moment, I would juz like to know whether my ECU is faulty. My car jerks for no apparent reason, after changing and checking all things such as; spark plugs, fuel pump, injectors, plug cable, throttle body....errrrm I thk it's abt that. But it still jerks?? Hai...tot of checking the ECU and fuel tank. Any idea? And would be glad if you could share how to check an ECU if I would hv to replace it. Thanks...
xerofighter : how abt manual? I'm driving manual. My car jerks as u've mentioned but no check lights on...what the heck! Cant seem to fix it. At the moment none of the mechanics are able to diagnose what's the problem.
Vacuum hose too is replaced! Any other things that would cause a car to jerk?? HELP!!! So damn frustrated to drive ever since, feel like juz taking a bus!
Bro, something like that though. It's heavier if air-cond is on. It will normally feel hard/jerking/hesitate to go during low rpms e.g. below 3k. Normally jerks as I accelerate from 1k~3k on each gear. Higher gear jerks lesser. Mine is a 6 yrs old car, considered old I thk, it's transplanted with MIVEC inside. Any idea what to check with the gearbox? Check the flywheel (didn't skim), clutch plate and clutch or check the gears area?? Thanks...
What actually the problem u're referring me to?
