Is the fuel pump priming?

 

[tom6361]

yes

 

[Aluco]

Got spark ?

 

[tom6361]

i would assume so as the car started for a bit but havent actualy checked

 

[tom6361]

are there no other forms of cut outs or safety sensors that could have kicked in, if you know what i mean

 

[f0xy]

only other direct cut out is immobiliser really

as said, check if fuel is getting to the rail and if its sparking

 

[tom6361]

the hazzards start flashing when i try to start it sometimes

 

[f0xy]

Has it got an aftermarket alarm or immobiliser fitted? Or just the standard renault system?

Tried locking and unlocking the car then attempting to start it?

 

[tom6361]

standard renault, cheers il try it now

 

[tom6361]

it almost went, it wanted too but didnt, so i tried it again but the battery's gone now. cheers guys

Another thing to check is....the red light in the center of the dashboard, does it go out when you are trying to turn it over? If it does not go out there is something immobiliser related stopping it from starting

 

[tom6361]

cheers il try and jump it in a bit and check

Bad earth 99.9% I've just had this happen to me spent hours trying to find problem.

 

[tom6361]

how did it happen to you? what was the proccess?

 

[tom6361]

foxy that red light is flashing as the car is trying to turn over

 

[f0xy]

I think that means the immobiliser is active then, it should go out when cranking as far as I know.

Do you have a spare key you can try?

 

[tom6361]

no just the one key, how could the key loose its code all of a sudden though all of a sudden, the wierd thing is the car ran for a bit though.....im stumped

 

[Dunn]

yup ur immobiliser is stopping it starting
it could of reversed it self
sit in the car
lock it with the key fob then try starting it

 

[tom6361]

that red light was only flashing because the batery was dead, just tried bumping it and the light doesnt come on

 

[Trev_m]

Try using a jump lead from engine to car body to create a good earth then a well charged battery, bad earths cause havok with the immobilisers on these.

 

[Trev_m]

Have you had the engine out or just the head off?

 

[Terry172]

TDC sensor as I know that allows the car to crank but won't let it start...have you checked this?

 

[tom6361]

hey guys, took the battery out, gave it a good charge, i assume the car re-set itself due to the battery being off over an hour, and it just started and went fine

cheers for all the advice though guys, top bunch

Tom
