Describe how you fixed your grounds.
I havent done anything to them. Got the water pump starter and engine replaced at a shop. Replaced the alternator and battery cables myself. The alternator and then later the cables have both resulted in noticeable lasting improvements. Checking and possibly replacing the grounds is what I was thinking of as a next step before messing around with the wiring harness which Im sure will be a hassle.

Depends, if it REALLY is a wiring issue, ground or not it’s not unheard of for a wire to pop off or have the insulation weakened.
Its definitely a power issue as what Ive replaced so far has had a big positive impact. I think something loose is possible but corrosion is probably a more likely culprit.

For sure, and now that you know it is a wiring issue, you have a good sense of where the diagnostics have to come into play, in this case wiring 👀👀👀👀

Ground strap is passenger head to firewall correct?
That would be one of the factory locations, but I am sure theres more than one also.
