mowerman Posted December 22, 2019 Author Share Posted December 22, 2019 Wow I can’t believe I was actually able to send that....... Thanks for the advice fellas I think it’s either a clogged line maybe collapsed or as Vegas said pump issues this time.....bob Quote Link to comment https://www.bigmacktrucks.com/topic/60270-dm-wont-start/#findComment-438587 Share on other sites More sharing options...

Freightrain Posted December 22, 2019 Share Posted December 22, 2019 Fuel shut off stuck?? I heard it's better to push them back in after shutting down to keep them from sticking closed. Air starter?? Saaweet. Didn't know you had that. Quote Larry 1959 B61 Liv'n Large......................

JoeH Posted December 23, 2019 Share Posted December 23, 2019 (edited) How cold was it when you tried to start it? Diesel fuel forms drops of gel that clog your filters around 17 degrees F and doesn't thaw back out until around 34 degrees. If you last fueled up in the summer or fall then you don't have the winter additives that prevent gelling. You're going to have to warm the truck up. My brother got fuel for his 7.3 ford last winter at a small station and it gelled up on him going down the road after 30 minutes. He had to tow it into my garage to warm it up so he could get it running. Not all gas stations run winter additives, so be prepared to add your own next time. Also modern biodiesel forms algae after a year or less of sitting. It will clog all sorts of annoying spots. They make algicide fuel treatments, but it only kills/prevents algae, it doesn't dissolve existing algae.

MACKS Posted December 23, 2019 Share Posted December 23, 2019 Get a piece of bicycle tire tube,tie off one end clamp the end around the fuel tank neck,air it up and leave it for a while look for fuel leaks in the lines,probably just a pin hole.. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/60270-dm-wont-start/#findComment-438693 Share on other sites More sharing options...

Paul prinzo Posted December 26, 2019 Share Posted December 26, 2019 Take a hose and make a line into a jug of fuel, after priming if it runs, it’s a bad supply line from the tank possibly. Loosing its prime, look into replacing the check valve on the return line at the pump. Mine is external on the pump and I was able to buy a new check valve on line and replace it for like 50 bucks Quote Link to comment https://www.bigmacktrucks.com/topic/60270-dm-wont-start/#findComment-438861 Share on other sites More sharing options...
