We found no spark on the plugs which is why we decided to change the
ignition coil.
Did you change the primary power stage with the coil? It's on a
small bracket attached to the
firewall at the rear of the coil, and has a TO-3 case semiconductor
(probably an SCR) and a connector
that the wiring harness plugs into. You need to make sure that
+12Vdc is getting to that connector when
the ignition is on. If the +12 is there, follow the instructions in
the Ignition section of the Bentley to test
the functionality of the power stage. If that's working, then just
follow the rest of the Bentley's test procedure
for the Hall sender, and you'll find your "no spark" problem.
I think the next step is to check the distributor more closely. What
are some basic tests of the distributor?
Again, follow the instructions in the ignition section of the
Bentley. They're pretty straight forward.
Also, any chance that it is a fuel problem and not an ignition
problem?
Would a fuel problem prevent the car from starting at all?
You may have a fuel problem, but until you have spark, all the fuel
in the world won't do you any
good. And, yes, a fuel problem can prevent the car from starting at
all. I recently went through that
myself, and it wasn't an obvious or straight forward problem to
solve. To make a long story short,
the main fuel pump was bad, but none of the symptoms were indicative
of that (except for the fact
that the car wouldn't start). The best advice I can give you
relative to that possibility is, just because
you have fuel squirting out of the (loosened) banjo fitting on the
fuel distributor that's the inlet connection
for the main fuel line coming from the main pump (with the fuel pump
relay jumpered to run the pump),
assume that the main pump is good. That was the scenario I had.
WIth the pump running, I loosened
the banjo fitting on the fuel distributor, and gas squirted out at
what I thought was substantial pressure.
But in the end (after going around and around retesting the transfer
pump and a bunch of other stuff),
replacing the main pump fixed the problem.
Any other suggestions would be appreciated.
Fix the spark issue, and if that doesn't cure the whole problem, let
me know, and I'd be happy to walk you
through testing the fuel system.
