A break in one of the 3 wires that go to the Hall sender plug is really common - they get really
dried out and brittle. And it will certainly prevent your van from starting - just yesterday,
after putting the engine back in my syncro, it wouldn't start. I had noticed that those wires
didn't look good when I was taking things apart, so it's the 1st thing I checked, and sure
enough the red one was broken.
I've had problems with all of my Van's Hall senders at some point - they seem to last about 200k
or so miles, when they start getting flaky and soon after- van won't start.
But if your distributor is new, then presumably so is the sender...I'd closely inspect that
connector, esp. inside the boot.
