Ignition Problem

[Mk2Kezza]

Have replaced any dodgy earth cables and ignition lights are on. Engine turns over but stops - seems like the timing may be out or that the leads or not in the correct order.

I have found the mark on the cam sprocket that shows tdc on cylinder one and the rotor arm points to 2 o'clock as shown in pictures. Still wont start though.



you can just see the indent on the cog.



I am right in assuming that from plug one its 1 3 4 2 in a clock wise direction?

[Mk2Kezza]

I mentioned timing, but not sure why that would be out as it wasn't before I started messing with the dizzy cap.

Just swap leads around. Eventually you ll find where number 1 is

[matt@onlychargeddubs]

yeah it's 1342 firing order and rotor arm wants to be pointing at the line marked in the dizzy body.

if it's turning then stopping that sounds more like a flat battery, does it just do like half n turn n stop and lights go off?

Update,

The reason it slows down spinning may be because the cylinders are filling with petrol too quickly. If I take out all 4 plugs then it spins freely but shoots out, what appears to be, a lot of petrol. I have also noticed that the fuel pump primes when you switch on the ignition but doesn't stop - like it used to? What could cause that to happen?

1-3-4-2 in a clockwise position? Just checking..

im afraid to say you have blown your ecu. very common problem when you lose and earth. when you go to start it the starter motor finds another path to earth which is very often through the ecu thereby melting the guts of it. they can be repaired but easier to just fit a replacement.

I read as such on a different post. I assume that they aren't made new? Is ebay the most likely source of a new ECU?

[gazareth]

sure is. there is allways loads of them on ebay around the £100 mark. its a wise idea to add an extra earth cable from engine to body just in case original decides to break. you could put one from rear engine mount to a steering rack bolt just to keep it out of sight. oh and I think there are 2 different kinds of ecu. they both work but you would be better with the 1 of the same part number as your original. I think the difference in them has something to do with the size of the fuel injectors. what colour are your injectors anyway?
