hey all been a while since been on here.
Just got a 2000F350 auto 7.3. Mileage is like a lot but seems to look like Moyer replaces.

Issues. No matter the temp outside truck will only start after being plugged in. Once started it runs great and has no hot start issues.

New IPR new starter new GP relay. Fuel filter and pump also.

Thinking Batteries as it does drop voltage when cranking. If not am I looking at injectors?

Any other input is great guys. Thx.
