I have spark. If i dump fuel into the throttle body, it runs and idles. The injectors spray but I wonder if they’re not spraying enough. The fuel filter looks to be new within the last few years. The top of the fuel tank doesn’t look like it’s obviously been opened. The truck did this last year around this time. That was solved with a injector fuse. It ran and plowed well all last year and I used it probably 6 or 7 times this summer on various projects. It doesn’t seem to like the transition from warm weather to cold but It throws me that it ran so reliably last winter once I got it going. I’m thinking it’s my fuel pressure regulator. Does anyone else with experience with these TBI systems have any advice?
