If you run into issues where the engine struggles with starting or accelerating, it’s likely experiencing a lack of power. With these types of Cummins diesel problems, you can most often link it to a fuel-related component. Be sure to check for:

How can I tell if my Cummins engine is having a problem?

The best ways to identify if this is the problem is first to make sure the tank has enough fuel. Next, check whether or not the pump is actually delivering fuel to the engine. If those are both correct, check if the pressure is low. Low cranking speed: The engine needs to turn over quickly for the fuel pump to generate pressure.

When does the long crank start on a Cummins?

Long….. Long Crank when starting Long….. Long Crank when starting Location:Vancouver, WA. Need your help. I started having the long crank issue 2 months ago. I was still on the original batteries and had read somewhere that as they go they will still turn the engine over but not have enough to send the signal to the fuel system.

However, if no fuel comes out, then it’s safe to assume that this is the culprit of your no start issue. In order to correct, you’ll need to replace the lift pump, and no better time to upgrade than now.

What causes a ram truck to not start?

First off, let’s get this out of the way, Ram trucks NEVER had the best luck with lift pumps. A lack of lift pump flow will not only cause a no start issue, but depending on how it failed, can cause other issues that we will discuss further into this post. The factory lift pumps on the 2003-2007 Cummins produce a dismal 10-11.5 PSI at idle.

What causes the advance piston to stick on a Dodge 24?

The problem will most likely be an internal VP44 fault caused by low or no fuel supply pump pressure. This causes the advance piston to stick in the advance housing bore due to cavitation damage. Another cause could be from faulty lead free soldered connections that fail over time in the pump PSG.

What causes a Cummins lift pump to stop working?

Some customers will notice the truck “falling on its face” or flat lining with power as the pump simply cannot supply any more fuel. After time, the pump will just stop working due to being over stressed and constantly running at maximum output. And this is exactly what we will be testing for next, the health of the lift pump.

How does the VP44 fuel pump work on a Cummins Engine?

It first produces the high fuel pressure required for fuel injection. The pump also meters the exact amount of fuel for each injection cycle. As the diesel fuel moves through the VP44 it is distributing the high-pressure, metered fuel to each cylinder at the precise time. The fuel pump then varies the timing relative to your Cummins engine speed.

Why does my car make a long crank when starting?

The reason for this is that the fuel viscosity is lower when the engine is warm also the clearances in the engine (injectors, CP3) are bigger causing more leakage. The CP3 needs to make 3000 psi in the rail before the computer will fire the injectors for a start. The case that is being described here is backwards from most cases I have seen.

What kind of ECM does a 1998 Dodge Ram have?

They utilized a VP44 injection pump which was electronically controlled by a Cummins 1 plug ECM P/N 3942336 (Engine Control Module)or FCM (Fuel Control Module) that mounts to the side of the block hence the terminology block mounted ECM. The 1998 & 1999 model years had issues with the “Wait To Start” Light not turning off.

How is communication between ECM and fuel injection pump module?

Communication between Engine Control Module ( ECM) and fuel injection pump module is monitored when ignition is on.

DTC may be stored if the time between CAN messages is more than 3 seconds or FPCM does not receive CAN message. 1.
