Ok, after a couple of weeks of inactively, I went back to the '76 B with '75
engine. As a reminder, I am having 2 issues
currently.
1) The car won't start. When I initially tried a couple of weeks ago, it
started and ran well (albeit with a bit of a high idle). After
some research, I determined that it might be the engine ground not set up
properly. My car has the ground strap on the
rear engine (trans) mount. I had connected it to the engine mount bolt
properly, but it was only tucked in between the
rubber mount and crossmember. So last night, I corrected that, attaching
the end to the bolt for the rubber mount on the
outside of the crossmember.
2) When the car did run, in preparation for a run around the block, I stepped
on the brake pedal and the engine died. I'm assuming
a vacuum leak and in fact there appears to be a small crack oin the vacuum
hose from the brake booster to the manifold.
That's the background. Last night, after fixing the ground strap, I went to try
the car. Battery is freshly charged, and when I turned
the key, the fuel pump starting making noise - not the normal clicking but kind
of a loud hum. But there was gas in the filter, so I
decided to try it. Car turned over fine but then there was what appeared to be
a 'flash' from under the dash (a brief burst of light) and
I let go of the key. There was NO burning smell and NO evidence of wires
smoking or being fused. The pump continued to hum.
I did not try and start it again.
Here is what the pump sounds like -

It isn't really as loud as it sounds but it is audible. I dsmacked it with a
hammer, no change.
Any ideas on the pump and that 'flash'? I am going to check the battery ground
cable and fuses tonight, but am looking for
ideas.
I'm not worrying about the vacuum leak until I get the car running.
