Okay, the main reason that I was replacing the battery cables is that I've got an intermittent hot no-crank no-start problem. So far, I've gone through the list of the obvious: replaced the radio suppression relay, replaced the crank angle sensor(RPM sensor), replaced the fuel pump relay in the fusebox, checked the connections on the fusebox and replaced the fuel pump fuses, verified that the fuel pump is working and replaced the regulator (as an earlier part of replacing the oil breather box, rear heater hoses, intake manifold gasket, fuel injector o-rings, and throttle body gasket and cleaning the throttle body and part of the intake manifold). I also replaced the ignition switch. And, I've cleaned every ground that I can find per the FAQ. We also checked the coil spark and it's good.

As I've posted, the most recent thing was to replace the battery cables due to noticing voltage drop and physical signs of cracking.

In the mornings, it starts up fine, with much better fuel economy since I performed the breather box and associated parts replacement. When it's running, I am noticing a minor intermittent miss/skip that seems to occur throughout the driving range, though I have been figuring that it is a possible plug/wire issue that I would address later. I drive it to work, drive it around a bit a lunch, then come out later to head home and have it not start. All the dash indicators come on, I can hear the fuel pump relay click and hear the fuel pump trigger, but get no crank at all. It will push start and then run fine all the way home. It will also restart immediately after I shut it off, but if I come back 5-10 minutes later it will have the no-start again. After between 1-2 hours it will start up fine and run again.

At this point I'm down to considering replacement of the starter solenoid )I have a good one) or the power amplifier stage, though it since it doesn't have any symptoms except the little miss during actual running, I didn't think that the power amplifier issue matches that.

Anybody have any other suggestions to run with?
