Engine failing to start

Recommended Posts

Hi guys. Want to pick your brains. On my sc, its failed to start this morning. It's always started and raced a little, seems to rev then drop, then rev then drop since I've had it while it's warming up but today, it just seems to turn over.

It started on the first turn of the key this morning and started to rev and drop then it cut out and won't restart. Any ideas of where to look/check first?

then you go here as i described in mp.. if the car starts with this plug disconnected --this plug is no longer good.If it does not start look for a spark ..take cyl 4 plug out if you have a spare plug ,plug it in and touch ground..someone should crak the engine for you so you can see if it has a spark..

let me know--again you not have any kill switch in the car ,right?

No immobiliser or kill switch. Will take off the connector on the back of the air box and try Ivan. Thanks so much for your help. I'll let you know how I get on

CDI box should emit a high pitched whine when the ignition is on.

It does Jonny. When the ignition is on the on position for a while then stops. Think this is normal?

No, it should whine indefinitely with the key In the on position.

Does it make a noise like air coming out of a balloon before the whining stops?

Thanks so much Jonny. You talking about the cdi unit and Ivan mentioning it too in pm and to check the connector into it got me to check. It wasn't! Took the connector off, gave it a quick blast of wd40, popped it on tight and we have startup! Been kacking it thinking something major had gone wrong. Learning slowly lol

Good stuff!

Thanks again guys. You know, my wife said to me this morning, did you move anything when you were playing yesterday? Of course, I wasn't listening properly. Two lessons there Ivan lol.

She still repeatedly idles fast then slow on startup rather than just at slightly faster revs. After a few minutes she then ticks over normally. Is this normal?

Think I'd be lost without this forum. You guys are fab!

Sorry for the thread ressurection

 

can anyone identify this part the connector goes to? Is it a microswitch in the fuel metering head and does it goes bad preventing the car from running?

Thanks
