SLEDOG Posted December 6, 2021 Author Share Posted December 6, 2021 I put a gauge at port where fuel temp sensor goes....there’s definitely no pressure when cranking. It pumps up to 55psi with hand pump.I have to wait until I can get someone to help me try to start it while pumping to see if it will start ....

Onyx610 Posted December 6, 2021 Share Posted December 6, 2021 Since you don’t have any help, go get a long piece of hose for your gauge so that you can read it from the cab when cranking.

Onyx610 Posted December 6, 2021 Share Posted December 6, 2021 JoeyMack, are these the ones where the gear would spin on the shaft? Or were those only the e-techs?

Joey Mack Posted December 6, 2021 Share Posted December 6, 2021 I think we are posting too many possible issues. The truck ran , then it ran bad, now it wont start, is that correct?

Joey Mack Posted December 6, 2021 Share Posted December 6, 2021 early E-Techs, But it is possible. In my experience it's the early ones... The one he has IMO was a better pump, just tricky to r+r the filter.. I welcome other opinions... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/68870-460-aset-no-start/page/3/#findComment-484301 Share on other sites More sharing options...
