Brand new battery. Not even two weeks out of the shop (for what that means) and it’s not lagging when I start it. It starts just fine the first time, but I try to start it when I have been in a store for 10-30 minutes, and it grinds. I’ve taken to backing into my spot so I can clutch start it if I need to.
The starter (rebuilt) is less than two years old, and I don’t drive the truck in the warmer part of the day because it has no A/C, and I’m a ol’ lady. A/C was never installed, as the truck was destined for Puget Sound, WA.
Umm..
You mean that the starter cranks but the engine won't start? (My interpretation of "it grinds"..)
If it cranks over and keeps doing that there is nothing wrong with your starter or solenoid. That puts you into the 'fuel' or 'ignition' area.
IIRC you have replaced a fuel pump, yes? (Posibly eliminating that part. Unless it has two fuel pumps, one in the tank - a pre-pump - and another external - a 'high pressure' pump. When it cools down does it start then? (It would still be warm if driven and then parked for 10-30 minutes...)
