Well here I am July 2018. Some may be wondering what happened with this truck. I put a toggle switch to drop out the alternator so I could get the engine to pull when I needed it. Then in Dec 2017 the engine started to knock so I had a crate motor installed. I told the shop how it won't run right charging and the new motor ran the same as the old one. So as a last resort I swap in the old original TBI injectors that I had changed out in 2013 to NAPA MPF 3-18202. The truck is now running as it did when I bought it in 1993. Can someone tell what is going on with these NAPA injectors? I fought this problem for 5yrs and 2000 miles.
