Renault megane not starting

I have an R reg renault megane thats refusing to start. It cranks up and is begging to start but nothing its literally right there ready to turn over but it won't very frustrtating as you sit there giving it some gas to power in to life.

The battery is showing 12.46 volts and is less than 2 years old.

I called the AA out who sprayed something called "E-Z start" in the throttle body I think its called and it fired in to life.

He said renault "migraines" lol are a nightmare with starting issues and electrical faults.

A diagnostic scan shows nothing is wrong. Well nothing electrical has triggered and MIL.

Any ideas what I can look at wiggle or poke next :)

If it runs with Easy Start, it might suggest a fuel problem. (You are

*sure* it has fuel in the tank, of course?)

First steps:

Can you hear the pump run when you turn the ignition on? If not, check the pump has a supply to it. If not, check fuse and relay. If you can't find them, post back with exact model details, and I will try to find them on Autodata.

years ago a renault foxed me, I even pushed it into the garage. It had been driven to me, I left it a few minutes and went to drive it in, but it would not go, it span over well, but no running. I eventually found that after it had been left for a few minutes the immobiliser kicks in, the key fob button has to be pressed before it re-activates. ocking and unlocking the doors does the job too.

Theres just over half a tank in it. It literally fired up as he sprayed it in and I started.

I can hear the pump prime/run as the ignition is turned. Its a 1.6 Renault Megane

I've done some googling and the symptoms fit the failure of some thing call a TDC sensor (top dead centre sensor) which I have never heard about before. Much be a French naming possibly but I believe its a cam shaft sensor from what I can see. Sits on the right side of the engine area, held in by 2 10mm bolts. Aparantly its a magnet on the end is a pin like thing which attracts metal filings, dirt etc and a squirt of electrical contact cleaner fixes this and then just reseat it and bolt up, cures many strting problems on renaults. Not sure if this is my problem but surely worth a try. That said its less than £20 for a replacement. But I'll try a clean of it first andsee how it goes. ALso read much on immobiliser issues to the point where some people have to scrap the car due to the cost of fixing it out weights the cost of the car! That from from renaultworld I think or one of the owner forums I was googling through.

I've had the car 3 years and have spent/wasted much of my life chasing faults I had the option of getting ford focus which I should have. I've owned a few French cars over the years and had some good experience with them in terms of reliability a shocker I know.

The immobiliser light behind the steering wheel flashes when locked and does nothing interesting :)

Its a bit of an odd one.

Getting the bus to work is proving expensive and challenging hehe been a while since I used the dire public transport out here in the bushes.

Thanks for the help so far all.

They are nightmares sometimes, you are not alone they have driven many to frustration. Theres no logic behind some of the problems!

Also worth mentioning the alarm is really twitchy aswell, with the bonet up and trying to start it the alarm goes off untill you lock and unlock it again.. I think its time to try and unplug the siren of the alarm so just the hazard go off and not my ear drums :)

The next car I purchase is going to be like fred flinstones car. Foot operated no sensors no suspension no frills hehe

Sadly, it seems it still foxes some garages :( Last year my Megane failed it's M.O.T on a broken coil spring. Booked the car in for repair/retest a few days later and when I went to collect it they told me they had had to push it out of the workshop when they had finished.

Locked /unlocked the doors and drove home, won't be going back.

I am glad I am not the only one !!! At least I found out the problem. Mind you 20 years ago immobilisers were quite rare as standard fitment on the cars I dealt with. Nowadays I avoid anything French like the plague.

Series Land Rover. You know it makes sense.

Or a Citroen 2CV.

Dangerous stuff, that. I once managed to blow the inlet manifold off an Audi A6 with E-Z start.
