Quoted:Is the wiring harness providing the proper volts / amps? (Not wire damage, but is it giving the right juice?)
It could be something else in the system entirely. (Dunno if cars still have these, but a bad voltage regulator can do all sorts of weird stuff.)
Yes, I've checked for both voltage and amperage.
And I keep asking but so far no one can or will answer, but I'll ask you too. Will a bad ground or wiring wreck the pump in less than 50 miles driven? And I don't mean just not run normally, but totally wreck it so that when I put 12 volts from an external source directly to the pump terminals, skipping ALL the wiring and grounds in the car, it won't run. And will that bad ground or wiring also allow a new pump to work fine and the car run fine, till the moment it dies?
That's what's throwing me. The only answer I can come up with is junk parts. But I can understand them selling pumps that don't last a year, but ones that don't last 2 weeks? They have to know they're going to be returned.
Anyway, going out to work on it again. This car is exhausting me. Pun intended.
