Gentlemen,

I have a problem that may or may not be unique but here goes....

When I park my truck with the front end higher than the back, I difficulty getting it started. It usually takes several attempts to fire up the engine.....

However, when the park the truck with the front end " Lower " than the back end it fires almost immediately after I try to start it.

It seems to be getting progressively worse. The truck is a 2001 Ram

Any ideas as to what is occurring ?

I didn't even notice this thread before. Let's see... have you changed the fuel filter yet??? Do you still have the engine block mounted electric transfer (lift) pump or has it been retrofited to the In-tank unit??? Do you turn the key to the on position and let the transfer pump prime the system or do you go right to start???

An early guess would be a filter or transfer pump issue. If it were to need a transfer pump, and it's still the block mounted unit, get a new one from the local Cummins dealer. If you try to get it at the Dodge dealer they will try to sell you the retrofit kit, which had sporadic reliability. Mopar doesn't sell the block mounted pump anymore. The new transfer pump may be slightly diffferent, requiring a slight modification of the mounting bracket. You need to test the fuel pressure on the low pressure side of the system, which is what the transfer pump controls. There is a pressure tap on the line going to the side of the VP44 Injector pump, just hook up the gauge and test the fuel pressure. Leave the gauge connected and leave it overnight. The next time you use the truck, turn the key on but don't start the truck. You should have at least 10 psi key on, at least 7 psi cranking. There is also fuel flow. Disconnect the rubber line from the outlet of the filter housing. Run a clear hose from the filter outlet into a 1 gallon diesel container. Bump the starter and let the pump run until it stops (25 seconds). Empty the container. Repeat the procedure. There should be no air bubbles, and there should be more than 45 ounces in the container.
