5.0 Mustang A9L/A9P computer - to borrow for diagnosis

Anybody have a spare one of these laying about? I have a no spark issue (out of nowhere) and have checked everything else I can think of and suspect this is going to come down to being a problem w/my computer. I could also go for swapping out my distributor to make sure the internal electronics aren't a problem...

Has anybody got an A9P or A9L (I just want to plug it in and see if I get coil spark), I could borrow to test these theories out?

Thanks for any help :thumbup:



Edit:no longer need a distributor

Checked ignition box, coil and TFI?

No box, replaced coil & TFI with working ones.

Getting no spark at the coil. I try to arc the spark from the coil wire to the distributor but am getting nothing out of it. I thought later that it could be the actual coil wire itself, but that seems pretty unlikely out of absolutely nowhere. All fuses are good, got a test light lit on both coil wires upon crank, fuel pump works and reaches the rails, etc.

Things I've had suggested to me that I haven't been able to look into yet, though I'm unsure how much they weigh into killing spark from the coil 100%:

- EEC relay
- ECU (internal capacitors)
- ignition switch
- stator/pickup coil/PIP sensor


So I figured I'd start trying to replace whatever I could to at least eliminate them as culprits as well.
