OK this may sound wierd but .... I have 95 Lantra and sometimes it just wont start, if u pop the hood and leave ot for 10 minutes and come back it does start.

So for example ... I drive to work, it starts fine in the morning, park the car. Leave it there all day and it doesnt start ... so i open the bonnet and come back in ten minutes and it works.

A mate of mine said that there may be a sensor or something that thinks its just to hot so it doesnt start ??

has anyone heard of that ?? does that make any sense ??

when you say it does not start, does the engine crank over?

yes it does

I had the same problem ,I took the car into the dealer,who found the batterywas too weak .I changed the battery and solved the problem.I would say get your battery checked out.

By the way that was my '95 Lantra.

Rather late to reply to this one but I could not resist as we have the same prob.94/95 lantra cdi 1.8 automatic. I found that this only happened in the summer on hot sticky days and all I used to do was to wiggle the relay about that was related to the starter. top left relay. Also sometimes helped if you ran through the gears. Its got to be a heat related thing as loads of lantra owners suffer it.

i had similar problem it was electrical, it was caused by DCU what was burned but not complite.

Since becoming a Hyundai owner I have studied page after page on Hyundai vehicles & I have come to the conclusion that Hyundai is still a pretty unknown vehicle on the mechanical & electrical side of things.
On many a page I have come across the big question is why does my Hyundai no longer start.
Well the dealership will tell you its a flat battery or a blown starter motor & try & sell you one at a sky high dealership price.
Well of course check your battery terminals first for a loose lead on the battery poles & the main earth going to the engine block/chassis also checkout your starter motor to see if it has any loose wires.

I have read that people cannot get there Hyundai's started so they sell them on as there tired of the problem & go on to think that Hyundai make rubbish vehicles.

Ok if you own a Hyundai Lantra with a manual gearbox & it suddenly will not start then read on.

If the leads are nice & tight on the above mentioned & your dashboard lights illuminate & your car still has all of its electrical functions online like lights/electric windows/etc then take alook under your clutch pedal.

Hyundai fitted a sensor switch unit directly under the clutch pedal.
On many Hyundai vehicles you have to press down on the clutch pedal while also pressing down on the accelerator pedal while turning the ignition key to start the vehicle.

The sensor button under the clutch pedal sends a signal to the engine management system to tell it to start the vehicle.

Just think in a vehicles lifetime how many times you dip the clutch to change gear & how many times this little sensor button is hit upon & the wear it has to suffer etc.

If your Hyundai suffers this problem while your out & about & your vehicle goes dead,then its a good idea to carry a 14mm open ended spanner to get you up & running again.

To fix this problem you will have to lay yourself into the footwell & reach up under the clutch pedal,where you will find the sensor unit button bolted in by 2 x 14mm bolt heads.
By adjusting the sensor switch sprung loaded mechanism more forward then tightening it up again will start your Hyundai 1st time.
As this will improve the distance greatly when pressing down on the clutch pedal.
Why on earth this gadget is put there in the 1st place heaven only knows.

If the sensor button shows sign of heavy wear,then you will have to replace it & this is a main dealer part only & will cost ££££ or $$$$ wherever your from,but if you are close to scrap yard or breakers you may be lucky to get one cheap & as mentioned,all you need is a open ended 14mm spanner to remove it & to pull out gently the small iso wire plug.

Always feel free to ask me a question as I have always owned oriental vehicles in all shapes & forms

Hi

My Wife's car has just started to have the same problem. It is a Feb 1995 Lantra GL auto. The car will start first thing in the morning but once hot it sometimes will not start again until I lift the bonnet and let it cool down for half an hour or so. The car turns over fine but just does not fire up. Once the car in running it drives fine and I can drive it for hours without any problems. The problem seams to be more prevalent in hot weather, which is a problem as we live in Perth and it's always hot.

If anyone has any ideas please I'd love to know. :liebe011:
