[Dave at Pelican Parts]

OK, it's not 3 & 4; it's 1 & 4. Definitely suspect the trigger points, the wiring from those to the ECU. The ECU itself is a lesser suspect; they typically don't fail, and when they do they more usually won't turn the injectors off, rather than not turning them on.

You can look into the D-jet tester that Pelican has; I think we still rent it out. Or talk to the local 914'ers about borrowing an ECU you can swap in.

Or talk to Jeff B about getting a "reubuilt" (I still say that 99% brand-new parts is more than just "rebuilt", Jeff!) EFI wiring harness...
