I had posted this recently in another members post and to bring it upfront I thought I would give it its very own posting.
I am having a similar issue with my 1991 Loyale-recently we installed a new starter and the car still wouldn't start, so then we noticed that the black fusible link was broken and luckily we had access to a replacement and switched that out. In March of this year I installed a new ignition switch believing this was the problem.
After switching out the black link--The car then started perfectly, I ran it for about a week or so perhaps maybe 100 miles, and yesterday I went to start it and it won't turn over. I have all of the dash lights come on, and hear the clicking of the fuel pump relay, however the car fails to start. We have gone around and around with these issues for almost a year now, the car has low miles about 80,000, yet the age seems to be its downfall. So far the car has a new battery, a new alternator, a replaced starter (however not new), a replaced fusible link (black), a new ignition switch, new battery cables, you name it-the part is probably relatively new.
Occasionally the car can be started by inserting a long screwdriver down into the gears of the flywheel and rotate the gear clockwise a notch or two and it seems the car tends to start right up. (however this isn't consistent nor is it practical for me to have to rig in order to drive and feel secure the car will start every time I shut the car down)
Where should we proceed next? I rely on the car for winter driving and would like to know this issue has been corrected by the first snowfall. Any feedback would be greatly appreciated.
