My 86 760T wagon won't start but cranks fine.
I tried a different powerstage, but there is still no power at the coil -
not even the 12V I should see.

Any ideas?
Thanks
Greg

Check the hall sensor in the distributor, and more likely, the connector
that hooks it up.

Power to the coil is direct from the battery via the 15R terminal on the
ignition switch. If there is no power at the coil either the wire is
broken somewhere or the electrical portion of the ignition switch is
faulty. Run a wire dierectly from the battery + to the coil + and turn
the key to test.

The goal when driving is to miss the maximum number of objects.

Or the car may have been modified with a "radio suppression relay".
Look for a black relay with 4 round pins mounted somewhere around the
perimeter of the engine compartment. If this relay is bad, you'll end
up with your exact symptoms.

If the warning lights don't come on, I'm betting on a bad ignition switch.
However, the power for that also comes from the medium-sized (6 AWG?)
connection at the battery, so that is worth a look-see.

The ignition switch is a simple DIY job to replace and is available from IPD
(www.idpusa.com).
