Hi Everyone, looking for some help.

I have a fantastic
![](./images/smilies/spacer.gif)
, yellow import tintop Mr2 SW20 rev2 n/a.
![](./images/smilies/spacer.gif)
It has a strange fault where it occasionally cuts out and wont restart.
![](./images/smilies/spacer.gif)
Ive been recovered from the roadside twice now so need to solve it.

My first guess was the igniter, strangely a rev 2 igniter isnt that easy to find so i had to get a previously enjoyed one.

Unfortunately the fault still remains.

Its a little better in so much that it will restart a few minutes after a failure.

To move things along i thave changed the plugs, leads, cap, rotor

, coil

, igniter again and also ran through all of the wires with a meter.

All connections have little or no resistance and look as new.

I have also added an extra earth or two.

Still worried about the igniter i have put a scope on the igf and igt wires and have a good signal.
![](./images/smilies/spacer.gif)
When it cuts out i still have igf igt activity so i think i can rule out the distributor and igniter even though i always get a code 14 error after it stops.

Im pretty sure that im lacking an injector pulse when cranking and not starting.
![](./images/smilies/spacer.gif)
I cant see any activity on my i1/i2/i3/i4 outputs.
![](./images/smilies/spacer.gif)
Is there another input needed by the ecu other than the igf to generate the injector output.
![](./images/smilies/spacer.gif)
Has anyone see this behaviour before

Any help gratefully appreciated
