Need to know what is going on with my truck.
Started out not running when I got it. Turned out
the spider injectors burnt up so we replaced
them and it ran great for a week. It sat for two
days without running, then I went to start it and
it wouldn’t start. Turned out the new fuel
pressure regulator went bad already. Replaced
that and then it started up but ran rough,
wouldn’t idle right, would stall out. If I put it in
gear it would die on me. It’s showing a P0122
after replacing everything. We put in a new
throttle sensor and a new map sensor, it ran
good for a minute then went back to running
bad. Need help figuring this out, any help is
much appreciated.
