It’s a 2002 Chevy 3500 cutaway G31 Skoolie bus 9500lbs 5.7L FI OHV 8cyl when i put in a brand new one it stared right up. Runs and drives. Left it a couple days nothing. Jumped it and started right up. I fear it might be something else. I used a scan tool on it and no codes but i still wanna show information. Maybe you all can offer suggestions.

Thanks,

Dave
