03 issues
I got an 03 Cummins brought to me that was is to start. It cranks for about 10-15 seconds before it'll start. After it starts it runs great!
He Took it to a shop n they ran a fuel pump test. The sheet from the shop says the pick up pump in the tank flowed under specs and is under pressure. The return flow rate is in specs indicating there are no leaking injectors. Recommend replacing the pickup pump in the tank. Because of the pickup pump being bad it could have damaged the high pressure pump. Will not know until the pickup pump is replaced.
Going on the shops note and the Guy wanting the pump changed, I changed the in tank pump. The truck has hardly any change after the pump change.
When the pump is running and the engine is off there is sometimes but not all times a high pitch squeal (kind of sounds like air being let out of a balloon slowly). I'm thinking fuel leak? There's fuel in the top of the motor mount below the fuel filter. I'm not sure if it came from the shops test or somethings leaking.
It also has a clicking noise when the key is on and the engine is not running. Is coming from around the back of the valve cover area.
So pretty much.... any ideas on what the squeal could be when the fp is running?
What could the clicking be?
What else should I check for with the long starts?
I'm pretty new to 3rd gens so any help would be greatly appreciated!!

Well the truck sat for just under 2 days and now all it does is crank but no start. The night before last it did seem to crank a little slow but it did start. I hooked up a code reader and it shows 2 codes for battery temp sensor. Could it be the batteries being weak causing it to not start? It has been 25-35*f around here lately so I would.think it could be the problem...
I talked to another diesel guy and he instantly said injectors but this was before I thought of the battery issue.
What y'all think? Batteries or In.jectors? Or something else??
