Joyner usa told me they feel it’s fuel. Not sure what else to try as far as fuel is concerned. Filter, pump, fpr and lines all replaced. Tank cleaned and verified via clear filter that it is keeping solid fuel supply. I was running 50psi, they said 60+ recommended so I will try that tonight. Did get a map sensor on the way and a new tps. My current tps when checking resistance was ranging from 2 at close to 7 at open. I believe I had read it was suppose to be no more than 2 at open.
