My mk5 won't crank over with the key but a wire on to the starter then battery it's fine but won't fire up. What could be the problem can anyone please help. This is driving me mad.

 

is the immobiliser light flashing? is the starter relay clicking?

 

The immbiliser light is flashing but it was flashing before it stopped working. And I'm not sure if it clicks, when I turn the key to the second stage when all the lights come on it clicks then, but when turn it to start there ain't any clicks then

 

the immobiliser light should flash every second or two the with the key in it should stay out. if there is a fault it will flash like fuck for a min the give out a code.

 

Nah it flashes every two seconds all the time with key in and key out. What could be the problem hope it ain't no major fuck up

 

It's does seem the immobiliser is armed, do you have another key you can use?

You need to find out if your getting power to the small wire on the starter when the key is turned.

 

Just re read, I assumed you had the ignition on, which in reality you probably didn't? Therefore it wouldn't start, hence not an immobiliser problem!

If this is correct then as said then you have lost the feed to the starter, a likely cause would be the starter relay.

So what do you think the overall problem is lads. The starter works when a wire is connected to the Cilinoid then to the battery. Might sound thick as fuck but we're is the starter relay. And before it fucked up when I put the key in and turned the engine management light come on it doesn't come on anymore.

 

Could be an ignition switch fault? Had to put one on my mk5 zetec s with slightly similar symptoms

 

So I need a new ignition switch??

 

It dépends when you turn your key to position 2 do your dash lights come on and then when you flick to start do you get an output?

 

All the dash lights come on when switched to position 2 except the engine management light. And I dont know which wire to test when switched to position 3

 

Can u see the starter motor easily I have seen a few of these snap the small wire going to the started, I don't think your ignition switch is the problem when u said before that the eml light wasn't coming on I'd assumed none of them were

 

To rule out an immobiliser problem jump in the car with the key in your hand the light should flash once every 2 seconds (ish) put the key in the ignition and turn to position 2 if the light stops flashing/goes out your ok, if the flashing speed increases then you have an immobiliser issue

 

I Carnt see the starter that good, and every light comes on except the eml before it stopped working the eml came on every time. And I will try the imbolliser trick

 

The light keeps flashing at the same rate about 2 seconds Ish.

 

I Carnt here the fuel pump running either

 

Sounds immobilised to me then if u leave the key in the ignition for a minute does the immobiliser light start flashing in a different sequence

 

Nope it stays in he same sequence

 

Hmmm, odd

 

It's doing my head in

 

If you also have no engine management light I'd say it could be a ecu power supply problem. Have you checked for blown fuses?

 

How could I check for blown fuses and that what I think it is myself to be honest

 

If the fuse has blown then it has done so for a reason, the easiest way for you would be to find which one it is (via the legend or the handbook) and remove it, once it's removed you can easily see if the wire has broken.

Martin

 

If a fuse has blown I will replace it no all that bollocks ur onabout mate

 

That told you Martin lol

 

Well you can't hence your here asking the question, to which I answered!
