My troubles began a month ago with 166000 km on my 2003 dually whamo LP gone so we replaced it with an in tank LP at the local mechanic. After a week or so it began to take longer and longer to start (turn over many times before firing) I thought it might be the hot air manifold because if I plug in the block heater it would start, but lately that does not work. We thought it might be the HP fuel pump, really not sure though. When it's been started in the morning it always starts through out the day but if it sit's for longer that 6 hours it won't start.

When it's turning over I have no oil pressure as well, I always thought It needs oil pressure for it to fire or is it different in the 03's. Any thoughts would be great!

Don't get your hopes up...Mine was doing same thing, it would start normal some days and not others??? No in shopp on day 16 and the CP3 is being replaced. It is not an injector issue as they replaced all six and did not fix the problem. CP3 should be in today, I will let you know.

Just another note, my fuel mileage shot way up just before the thing would no longer start.
