Started having trouble with my Excursion 6.0 Diesel stalling after being in tow/hauling a 22' boat. That issue has gone away buy now I start it and run for 20 minutes, turn it off and try to start it again and all it does is turn over. If I let is sit for about 8hrs it will start again. Does anyone know what is going on?
Thank you,
Kelly
Common no-start issues on a 6.0L related to the engine warming up are leaks in the high pressure oil system. There are too many o-rings to count easily in that system, which is why leaks tend to develop there. Without spending some time with a scanner then pretty much every thing to try to fix the issue is a guess, and with how expensive some of these parts are guessing costs significantly more than buying a DashBoss or TorqueApp and spending an hour taking down a list of readings. Even worse, taking to a shop that will guess will hurt a LOT, doing some basic diagnosis on your own first can give you some insight before a shop tells you to start replacing an $800 oil pump when the real problem is an o-ring on a $75 standpipe.
