just bought: cranking, but not starting, no codes
I have a problem, maybe someone of you has some hints for me. A friend of mine just bought an 03 6.0 f-250 powerstroke, which here in Austria is a quite rare truck. When he checked this car before bying it could be started but was not running fine. So some mechanic of his changed the 3 fuel filters - and now, the rigg does not start at all.
So I was called to check it out. It cranks perfectly, some cylinders fire up (which makes the starter disengage) but refuses to run. With some starter booster fluid we could manage to run the engine for a few seconds, so from the mechanical side, everything should be fine. As it is quite warm glow plug operation cannot be the cause.
I checked the codes (Auto Enginuity Tool), but no major codes stored (one old "water in fuel" code and something total unrelated.
The software triggered injector test said, that everything is o.k.
What I can see is that someone sealed the fuel regulation valve with a lot of sealant, I opend it and also found a lot of sealant inside, so I assume these sealant parts could be washed somewhere where it should´nt be.
I have no possibility to check the fuel pressure yet, but at the fuel pressure test port it seems there ist alot of pressure when trying to hold it shut whith my thumb :-)
As this truck is very rare where I live I cannot swap parts with a similiar truck to narrow down what could be the cause.
Any suggestions what to look for (except fuel pressure)? Any bleeding procedures necessary?
Thanks and greetings from Austria!
