2002 Cummins starting & running questions
On my dodge, when I'd get below 1/2 tank of fuel, it would sometimes take several extra turn overs of the engine for the engine to start. Usually it starts very quickly, even in colder weather. Lately, I've noticed it is happening more often, and even at 3/4 of a tank of fuel. It seems like only sometimes I am losing my prime. The time the truck sits before starting the engine again doesn't seem to matter: Sometimes after sitting for five minutes, it takes awhile to start, yet sometimes after sitting for a few days it starts right up.
Second issue is I noticed a high pitched whistle when accelerating on the highway around 2,000 RPM. I'm guessing this is a leak in the intercooler hose, blow off valve, or intercooler? Is there a common place I should look for leaks? How can I find a leak like this? Thanks in advance for any advice!
