Ignition problems

[Ben Swann]

Christo,

What engine/ECU system are you using.  I am having (possibly similar) problem with aan MC transplant into an early GT Coupe that I have yet to resolve.  

See for details:

Sounds like the pin/wiring you describe is similar as what I have outlined here.  And your problem sounds similar.  My Hall sender tested OK  - at least by the book, and I seem to have continutity on my wiring, but there is obviously a breakdown in some discrete component somewhere.

I will be resuming trouble shooting on this next week.  I had to put this problem on the back burner since I was not able to identify the problem with the several days of testing I already did.  I'd be very interested in knowing what you find - anything to help me get this one resolved.

Where/What is HF8311A?  Is this the darlington transistor that is mounted to the coild pack?  Something inside the ECU?   I already tried swapping both ECU and Coil Pack in my trouble shooting - both were known working units.

just one little step.....
last night after make some wiring work I've got a right ignition signal on pin 22 from my ECU when I ground pin 2, and connect test led between pins 2 and 22.. turn on ignition, and try to start the engine and the test led BLINKS :)))

so at this point I have one problem - how to trigger the coil. HF8311A seems
to be failed, so I must find a replacement. bad thing - I dosen't have an
idea what's the spec of this HF8311A.
Have some one changed this trigger transistor before?
