I have a starting problem with my 1999 Honda accord, 1 in every 50 starts for example the car will turn over but fails to start, I repeatedly turn the key then the crank slows down but still doesn't fire. it happened today at about 12 o clock gone out now and its started first time any ideas what this could be? thanks

An intermittant like you have described can be an absolute nightmare to track down. A visual inspection of the engine management system for loom damage or corrosion, contamination or oiling of plugs. You can connect a data logger onto the vehicle to record any mis-function when it does not start. A OEM scanner may also reveal the fault. Main suspects for me would be crankshaft sensor, camshaft sensor, or engine management fuses or relays.


Could have an idle air control valve Issue, if valve sticks open will cause a big vacuum leak which would cause a no start. Next time it happens try taping litely on valve if starts replace valve

  • Idle control valve is located on the back side of intake manifold by the throttle body or you could simply go to
