Wayne, My first thing to look at would be the connection on the bottom of the inertia switch, make sure it's tight and the plastic isn't melted. Then has the old blue coil been replaced with a new one or up dated one. Then I would check the pulse coil connection and check the ohmage cold and hot. Normally it will go from 580 low to about 700 high before it breaks connection. Make sure the fuel pump harness isn't loose or a bad connection.

Coming home tonight, I stopped for a traffic light after driving for maybe 3 minutes, and the engine suddenly started to stumble as if I was out of gas. (Gauge shows half full, and that's probably correct.) It nearly died, then began to crawl forward just enough to get me out of the intersection, out of the way. Then suddenly it went away, and I shot off like a slingshot. Background: the plugs, wires, distributor and vac lines are less than a year old and professionally installed. The fuel pump is too. The other fuel tank innards and hoses were all replaced about 6 years ago. Warm up regulator and thermotime switch also about a year old, as is the... I forget the name... fuel relay? in the electrical compartment. I have a blown head gasket I haven't repaired yet, but could that be the issue? In my driveway 5 minutes later it started to stumble a bit again, and oil pressure showed about 40 instead of 80, unless I revved it. At least it would rev. I spent thousands on tune up related issues last spring at my usual D vendor, and the car was fine. Now what?
