Supermutt Posted December 30, 2023 Share Posted December 30, 2023 So forgive me if the answer to my problem has already been addressed, but I have searched extensively and can’t find anything. So this is the series of events. drove the truck home, it was running awesome. Shut it off at 9:30am. Then went out to start it at 5:30pm to move away from shop. It started instantly. But while building air it only idled for maybe a minute then stalled out. I tried to restart it and nothing. Definitely stopped getting fuel. Today I pulled the fuel filters and they were both down about an 11/2”. So it definitely starved for fuel, but why ? it has the Ambac pump, but it does not have a hand primer. I am stumped. Shut it off and it croaks. thanks in advance. It’s been 30 years since I worked on an e9. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 31, 2023 Share Posted December 31, 2023 Either a air leak or blockage Paul 1 Quote Link to comment Share on other sites More sharing options...
Supermutt Posted December 31, 2023 Author Share Posted December 31, 2023 Ya, it’s just really weird that it was running like a bear. Sits for 8 hrs starts right up and quits. You don’t think anything in the pump let go ? It’s definitely not pulling fuel now. Quote Link to comment Share on other sites More sharing options...
terry Posted December 31, 2023 Share Posted December 31, 2023 Can you check between lift or supply pump and injection pump to see if you getting fuel there? That’s where I would start. Terry 1 Quote Link to comment Share on other sites More sharing options...
Supermutt Posted December 31, 2023 Author Share Posted December 31, 2023 It’s not filling the primary or secondary filter all the way up. So it’s not getting to the pump. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 31, 2023 Share Posted December 31, 2023 Sounds like you have a air leak in the supply side but when the motor isn't running it is getting siphoned back up the return to tank side This allows it to run for a few moments before it dies from no fuel Paul 1 1 Quote Link to comment Share on other sites More sharing options...
