No spark on a '91. Puzzler...

~The Jester~ · 02-27-2005, 02:57 PM

A friend of mine has a '91 Grand Marquis. Car was running fine until he changed the thermostat yesterday, then it wouldn't start. So he went and got himself a new TFI module, and still no spark. Out of desperation and not knowing Fords (Shivvy guy, working on wife's car) he takes the spud connector out, and all of a sudden she runs. Puts the spud back in, and she still runs.

WTF??? Any ideas?

Loose connectors in the TFI harness. 'Nuff said.
