I have a fantastic
, yellow import tintop Mr2 SW20 rev2 n/a. It has a strange fault where it occasionally cuts out and wont restart. 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.
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.
I cant see any activity on my i1/i2/i3/i4 outputs. Is there another input needed by the ecu other than the igf to generate the injector output.Has anyone see this behaviour before
?Any help gratefully appreciated
