in tank pump is totally dead. THAT has been the issue. removed supply line from main pump, then removed fuse #4 and jumped to right side - no gas coming out at all. so the intermittent problem and starting issues have been related to a dead in-tank pump. unsure how long.
Wait a minute... in the very first post, you said the intank pump was drawing 3.1 Amps -- which implies it was functioning, even as you were beginning to chase gremlins. And you sure have mentioned a lot of 'em.
The problem with intermittent problems is you can only troubleshoot when it's happening.
Bingo.
- car is getting spark, ignition timing is steady at idle, BUT the car did die at idle with tach light attached to battery after ~2-4min. It would not start for a period of time, then started back up and idled strong for ~20min.
Getting spark while it's idling is irrelevant compared to knowing if it's getting spark as you crank it when it won't catch. A cheap inline spark plug checker would tell you a lot, if you can see it while you're cranking...
i wonder if my ignition coil may be the fault? but would a coil fault create this intermittent condition?
That was my very first instinct. Dying when hot is a classic symptom of a bad coil winding.
While I suppose there are many items that can temporarily fail when hot, and then magically work again 1/2 hour later, the two that come to mind the most rapidly are ignition coil and main fuel pump.
