So finally after years of slowly addressing cold start issues I ended up trying the shimming of injector armatures. Once completed the truck started right up. Let it run for about half hour while i checked fluid levels. I did notice a quick miss or slight stall twice before taking it on a test drive. While on a test drive i drove it for about 10 miles before it just quit running abruptly. Have bot had a chance to look at anything other than HPOP Level. Any help would be great.
