Hi Barrett, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, any code?

Also measure battery voltage; Off, On, idling and when revving.

Still, it could either be an ignition/electrical problem or low/poor fuel delivery / starvation issue. Proposed preliminary checks (if have not been done) on potential suspects:

  • • drain-clean tank and replace with fresh fuel (even if just to eliminate as a suspect);
  • • check/clean fuel path including fuel filter and fuel pressure regulator (least likely);
  • • check/soak/clean injectors to ensure spray output is in a conic dispersion (likely);
  • • test fuel pump's output pressure of 43psi (most likely).
